 Legally you are nothing more
than an extended cable linking his HP-48 to his emulator
So where could I get it ?
(My cable port is just fucking dead )
By the way , how strange it is that a PSX emu is easier to find than an HP 
rom ...
 
I wasn't putting down Erable at all.  It's just hard for me to remember all 

the
commands and such.  Some people might have an easier time, but the commands
(especially the trig transformations) I found hard to understand. 
I do, however, swear by Erable.  It's the algebra system I use, and I'll 
never
stop using it until the new HP comes out.
 
My HP48GX does not keep accurate time. It was off by 8 minutes after
several
months. Is this normal ? Is there some way to make the clock more
accurate ?
---------------------:: o
i think that there's an application to help with this...
but the theory is quite simple...
just determine how much it's gaining or loosing every...say...week, and 
then
set an alarm to go off once a week and reset the clock for you...
you may have to manually reset the fudge factor occasionally...???
 There is an other factor that may help you in having a more acurate time.
it seems that the 32Khz cristal in the 48 needs a bit of ageing in order to
find it's stability (a litle bit like a car that you needs to drive slowly
for a while before using it realy).
If you put new HP48 in an oven at, let's say, 40¡C 95% of 
humidity for one
week, you will see that you may have up to 1 or 2 hours of differences
between the calculators, But If you try again with the same calculators 
one,
then the time differences will be bellow one second.
I do not know how long it takes for the cristal to age, but if you always
kept your calculator at 20¡C, standard himidity, the ageing 

process may be
quite longer and may be the reason of your calculator time keeping problem.
 
Shim that would allow me to make `{Commo} v. 7.7' run on top of the
`PC/TCP' ~PPP~ packet driver correctly, and then get functional `ZMoDem'
file transfers, eventually, euh...  And then, as i was quite distracted
with my discovery of the newer `MS-Kermit v. 3.16 Beta-7', at Columbia's
site:  i followed an `HP-48' related hyper-link, euh...  and that's what
finaly lead me to your post on the `HP-48' cassette-tape problem...  %^)
I happen to have bought myself an `HP-48S' 7 years ago and i DID address
that issue - i couldn't do anything else but just read you further!  8^)
     The answer is -=* YES *=-!  I've done that (September 3rd, 1993)...
Actually, THIS TYPE OF MEDIUM HAPPENS TO BE UNI-DIRECTIONAL, just as for
the `MSX' case (back then, myself i had a `Timex/Sinclair-1000 ZX-81'!).
Anyway, because of the Uni-Directionality aspect, i needed a Modulator/
Demodulator that's more like a ~MoDem~ for Packet-Radio than the usual
type which we use for Dial-Up accesses, thru the phone line...  In fact,
i bet it was quite comparable to packet-radio because the VARIATIONS in
the Audio-Cassette Tape Recorder Motor's SPEED, euh...  well, they must
have been just as bad as the frequency/phase-shifts that would be caused
by the movements in the ionosphere, euh...  %-b  Oh!  And the Quality of
my Cassettes & Tape Recorder...  no need to mention they weren't optimal
neither!  %-o  In short, it was quite likely that a number of bits would
get CORRUPTED at times and I COULDN'T BENEFIT from `KERMIT's ROBUSTNESS,
because of the Uni-Directional nature of the medium.  I ended up writing
a uni-directional protocol, in addition to the chore of building a kind
of MoDem which would have the required Cassette-Tape Interface:  Audio-
In and audio-out...  %-)  As a bonus, i also devised a Remote-Control
Interface to plug into the player's sub-miniature (2,5 mm?) jack...  It
worked by Monitoring the calculator's ~I/O~ Serial-Port Status.  Early,
from the begining, i got the impression i would need that feature in the
course of the program writing process.  So, i added a ciruit in order to
be able to control the motor by using the OpenIO & CloseIO 
commands.
     Overall, the cost to build the hole thing was about 120 $ Canadian
How easy it would have been if only i just had found a way to send back
the required control packets for `Kermit' to validate my chunks of data!
Euh...  But my Audio-Cassette Tape Recorder didn't echo the information
it received and, much less, it sure didn't calculate/assemble any of the
nice `Kermit' control packets my calculator could have used to conduct a
data validation process, by using my internal `HP-48' `Kermit' protocol:
surely, `Kermit' -=* ISN'T *=- Uni-Directional friendly!  8-o  Anyway.
     Well, appart from the medium's terrible lack of reliability, i also
had to write my program in the default `HP-48' user language:  i did not
know any better!  So...  i couldn't even count on the speed of assembly-
code to compensate for the wild tape-speed variations!  :(  As a result,
i was under the obligation to write my code in a way that would account
for the many lost bits, without the means which FEED-BACK loops provide.
Finaly, i opted for a gross strategy which circumvented the difficulties
simply by just -=* HAMMERING *=- the SAME bytes out!...  5, 7 or even 11
times in a row, hoping that something would still remain of the repetion
PATTERN and be revealed at playback time!...  There's no need to mention
that the rate of my special aparatus was slow, REDUNDANTLY SLOW!...  %-D
Though, if i had been a talentuous `HP-48' Machine-Code programmer (AND
mathematician!), euh...  maybe i'd have been capable to use COMPRESSION
on the data, TO COMPENSATE FOR THE NEED OF HEAVY REDUNDANCY - i wonder!
     Because my lack of know-how in the matters of Error-Correction (in
a Uni-Directional environment, especially!), i developed what i called a
MAJORITY-VOTE strategy.  Because my lack of programming skills, i also
resorted to a practical way of overcoming the code's slowliness:  i used
the OpenIO/CloseIO commands to compensate for my program's 
handicap,
by SWITCHING the motor ON & OFF, via the Recorder's REMOTE-CONTROL jack!
That way, it bought me the time my program needed to make the Majority-
Vote.  Simply put, the first step was to sample *AS MUCH* data and *AS
FAST* as possible;  then, the next step was to PAUSE the recoder while
the accumulated data was scanned for successions of a same byte (an ODD
number of them).  For example, if 6 bytes out of 7 had the SAME VALUE it
meant THIS was the ORIGINAL one and the extraneous noise was crudely but
effectively sorted out.  After this filtering, SYNCHRONISATION became
possible and a step-down COUNTER could be decremented as well.  A length
other than odd would have done no good as it possibly might have lead to
EVEN vote outcomes, HAMMERING 5, 7 or 11 times prevented a STALE-MATE.
                                ^  ^    ^^
     In the following months (once upon a time) - one beautifull day...
an `EduCalc' advertisement strucked me right in the face when i saw it:
it was about a stand-alone 3,5 in. - 720 Kb diskette unit, ~500 $ total!
My understanding is that it was a nano-computer running as a `Kermit'
server...  Then, i became aware of the PC `Kermit' program and i started
to think of buying an old `PC-XT' for 100 $ instead...  I finaly did and
that's how i got attracted into the PC arena, then bought my 1st MoDem a
bit later...  After that, my interest for the `HP-48' kind of shifted to
that of the PC, but i kept my `HP-48'.  May i suggest you try a PC?  ;^)
                                                  Best salutations,  :-)

  One of the things that makes the 48 so incredible is its tremendous
flexibility. It is a very open environment in which to work.  Using the 48
is like walking into a big, spacious room where you can see all the tools
available at a glance. Most other sophisticated graphing calculators are
much more restrictive. Some are like walking through mazes, you go into a
certain 'mode' then when you're done there you 'back out' to go into a
different mode,etc.etc. To use the 48 as an algebraic, you just press the
 ' ] key, from then on all your keystrokes are recorded just like on the
TI's (456/34*17+3 or whatever) and when you're finished you press [EVAL].

command WAIT. This idea would work also around midnight. Put the
minutes you want to rest on the stack first.
<< 60 * WAIT 
800 .3 BEEP 1600 .6 BEEP 800 .6 BEEP
Modify the BEEP sequence if you want to. When your sleep is very deep
I would suggest to play the BEEPs much longer (not .3 and .6 seconds)
or choose another frequency you don't like (to wake up ;-)
 
I don't really know how all the syntax works (Alarms is one of the few 
things I
don't use my calculator for) but here goes some code:
<<

M .30 + 'M' STO
M .6 - 'M' STO END H M + STOALARM
store this as some name, and hit this button to sleep for 30 minutes.
yes, but you have to know the lib ID.  Go to 
Left Shift 2, PORTS, whatever port the library is stored in, and then its 
ID
number, to put it on the stack.  Then transfer as you will.

Well I never new about the PCOEF command until now and now have found a way
to remove some iteration from my code.  More mini challenges using obscure

I'm glad you asked!  There are many programs available on the archive that
do this.
The most commonly used one is called ITABL and it is in MathTools7.  I
have a stand alone table program that is very fast and easy to use
available at the software archive.  Give it a try and tell me what you
think.
 
 
both table and msub are located in the math/misc section of hpcalc.org
well, I'm glad you like it.  I have been making changes to it frequently so
keep
you eyes open.  ;-)
I just updated it recently, I will send the newest version to Eric sometime 

this
week.
 I have encountered a strange (at least to me ;-) effect:
Put the EXTERNAL object including only the PTR to TRUE on the stack:
PTR 3A81.
Then store this EXTERNAL object (yielding TRUE now!) into a global
var. RCL this variable and see with ED what the EXTERNAL is containing
now. It's the ROM PTR BEEBB!!!
What's the reason for this effect. By the way, when I store the
EXTERNAL (with the content FALSE) the same thing happens.
:-???
 
Anyone knows wether it is possible to see the different steps of the 3
elementary row operations applied by the HP48G(X) ?
The RREF command only shows the final result.
 
I had a problem losing data on a card I bought from Cynos recently.  I have
3 hp48's and it worked fine in 2 of them but not in the one I bought it 
for.
description
of the problem and they asked me to do some fairly obvious tests, which I
did, and they decided it was a defective card and asked that I send it 
back.
I did.  They sent me a replacement and it's been fine.
I'd let them know right away.

because many people have problems to download their HP48 ROM, the ROMDump
Wizard was created. But the ROMDump Wizard versions 0.x are slow, may crash
Avenards ROMUpl program. It's fast, works very well, but needs an external
XMODEM terminal. So why don't mix the easy use of the Wizard with the power
the use his ROMUpl program in the Wizard.
You'll find the new version on my homepage at
http://privat.swol.de/ChristophGiesselink/.
 
You mean 32E, non-programmable but with linear functions or 34C,
programmable and keeps data in memory when switched off.
A 67 or 97, but the card-reader for the 41 can read the programs too with
some minor exeptions _and_ the 41 has a wonderful keyboard, of the 32E,
34C, 41C[VX] and 48GX I like the way the keys work on the 41 most. Oh
before I forget the 41 can be connected with HP-IL too and can use a
nice little wand too, that's a way of reading programs. :-)
- 
Just wait a few years and you will be the geek wanting another one of the
calculators that you have today but can't get anymore.
Heck, I wish I had time to write a 41C (my old calc) program to run on my
660LX.
G'day

But then what is a newbie to do with Library Data on his stack?  :-)

I have a HP48G and want to upgrade its memory.  I found the page:
http://studwww.eurecom.fr/~grundsch/page_upgrade.html
On this page, it shows you how to upgrade your 48G to 256K RAM.
However, I don't know where to order these chips and how much they
cost.  Can someone show me where to get it or how much it cost?  Also,
if you have done the upgrade...any helpful hints?
I list the parts below:
2x 128K (8bit) static ram chip SMD package (SO32)
                                       GHamn XX
                                      
                       by Per Blomqvist 1998-11
GHamn is a library that display the amount of used memory in the
different
ports of your calculator and RAM-cards. It's a hack of the ALLMEM
library,
and some other stuff that I have piracy. In the menu-label you can
choose 
to view the context of the port, view all attached library in the 
calculator, and backup the port to computer. 
It needs UFL.
 The HP-PC is not necessary but is needed if you press the bottom for
 backup to PC. The previous version X needed Fin's Hack library, but
this
 does not.
There are checkroutins for this library's in the program.
The menu in this program is a modification of Edurdo's example 14.8 in
his
Programming in System RPL document on page :
But I must say that it's much there I didn't understand, only copied.
And I have this new presentation routine that is scrollable. 
I have made it my self, and are written in ML.
You can get that standalone program out on the net, it's called AHA.
IM wery proud of that. 
__SYNTAX____
* To move from different ports:
        Then you can press [+], [-]. Or the menu-label that looks like 
piles.
        
        Or you can press [MTH] and type in the number of the port you
        want to go to, be careful and type in only numbers. I have limited  

        check on this on, it only makes range check.
* Keys inside the precentater, used by 'show' 'all.l' below.  
        This is a ML program that I written my self. And I proud of it.
        [ UP]  - key code 11, display one line up.
        [DOWN] - key code 16, display one line down.
        [PRG]  - key code 8, display one screen up (ten lines up).
        [STO]  - key code 14, display one screen down.
        ( same keys as VV in JAZZ for text object )
        And then there are two quit bottoms, [ENTER] and [DROP].
* View the context of the port:
        menu-label that 'show' stands. And the secund show program is under
        leftShift and same button, who also show the size of the objects.
* View all attach library:
        Press the menulable key  with those rectangles, and if you want 
        to second routine who show the size is leftShift and same button.
        I think the bought take the same time.
* To back up the port press that symbol that I have tried to paint so
nice.
  First type 'pcrecv' in dos on youre computer.
  But remember here to be in a path in your calculator were there are no
  variable/files in the VARS that have the same name as the thing in the
port.
  My back up program does the following:
   It recall the library/variable and strip the tags from its name,
   then save it in the current path and send it to computer, and then
purge it.
   If it is a library - were no variable can have figures as name, here
I yest
   put a char fist in the name. The char I have choosed id 'L'. So a
library 
   in some port with the name 909, will be saved on the computer as
L909.
   And it send a file called 'README.TXT' witch is a text file of what
you 
   also see if you press show button for that port. The same rule for
variable
   go for that to. The text file on computer have nullchars in the
beginning
   and make some words disappear or invalido, it's a know unfixable bug. 
   If you want that info in the README file, you have to change it by
hand.
   
   One more thing the send program seams to fail if the size bigger than
   half of the available memory. But theirs not many files that are
bigger
   than 60 Kbytes, probably only JAZZ. Keep this in mind.
* To exit the program press that nice boneskall with those X.
  Or you can press CANCEL.  
_______ CHANGES __________
Changes from v: X to v: XX
* MENU   I now have picture on all menulable now instead of that boring
         bread text. 
* To move from different ports
        Then you can still press [+], [-]. Or the menu-label that looks 
        like piles. Now you can go directly to a specified portnumber,
*       press [MTH] and type in the number of the port, be careful with
not
        typing something else than number! It's only range check.
        That input routine is stolen from gd10, READ by Fatri Mohamed.
* [Show] the context of the port, [ENTER] does not work for that in the
         new version. Only the menulable key under 'show' works for that.
         And the left-shift for same button who also show size of the 
items.
         And the programs for that is rewritten and are almost 5 times.
* [Show all lib] Well there is a picture now on than menulable, who I
think is 
        better. The routine for that is change and is TEN times faster 
        than the old one!! I have about 50 library installed on my 
calculator
        and the old routine took about 30 secund to get the data, now 
        it takes less than 3 secunds. And the Left-shift version is also
        changed and also wery fast.
* [back up] port to computer, does now also send a file called
'README.TXT'
        and show the context of that port. -Same info that you get when
        you press the show menulable key, are send to the computer.
        But there are some nullchars in that file that can make some
        word in the file on computer disappear, this is a known bug and
        I think it's unfixeble. It's only to look on the file and
        fill in by hand if you want it.
* Precentater Or choose program also awailabe on the net called AHA.
        A fast ML program I written my self. used by 'show' and 'all.l' 
        
* Quit You can now not quit the program pressing the [DROP] button
       because that button is used by my precentater program AHA.
 ========================================================================    

                       
                                      AHA    
                                      
                       by Per Blomqvist 1999-5
AHA is a full screen choose box, or can simply be used as a presenter 
of data in strings. It uses UFL font3 with no menulable. It is a attempt
to look like EC browser in JAZZ, I first tried to hack that out but
could
not figure out how it works.
This program takes a meta of strings.
Then you can scroll through the levels of string with the keys:
  [ UP]  - key code 11, display one line up.
  [DOWN] - key code 16, display one line down.
  [PRG]  - key code 8, display one screen up (ten lines up).
  [STO]  - key code 14, display one screen down.
 ( same keys as VV in JAZZ for text object )
 And then there are two quit bottoms, [ENTER] and [DROP].
 [Enter] - key code 25, button puts out the line number of 
           the top chosen line, and the flag number 1 on the stack.
 [Drop ] - key code 29, puts only out flag number 0, represents FALSE.
I don't know way it does not scroll properly like EC, you have to press
the button agen and agen to scroll, not only hold it in like on EC to
move.
I have a active key waiting procedure, this means that the processing 
indicator is on all the time, and the screen can flicker a little if 
you have low contrast. I want to know how to change this!!?
____EXAPLE OF INPUT____
5:  mama
4:  mind
3:  moon
2:  moron
1:  4 
This is yeast a small example with  only one screen, so you can't 
change the screen with the key [PRG] and [STO].
And then you can test quit with either [Enter] or [Drop].
You could also test 
1: 0
This is a null meta.
I think I have thought on everything, no bugs. It should work on the
S series to. Otherwise send mention to me.
No it does not check if the meta is of strings, so if some of the 
elements is nonstring the writing on the screen stops on that line.
I don't think that would do any more damage, and if something would look 
invalido on the screen in some wired case, it should probably not
corrupt 
the memory because it's only 'reading' from the memory (not writing).
If the strings length is bigger then 33 chars, then it's only 33 of that
string that is displayed, the string can be of what ever size.
______Extra comments_______
Im a novice on programming in ML, so I post the source code here to
and hope to get comments and idears about it.
The tool I used is JAZZ. The documentation about ML I used was:
  -Arnold Moys ML examples.
  -F.H. Gilberts 'Introduction to Saturn Assembly Language'.
  -Daniel Lindstrm, Source Page.
  - And SASM Reference Manual.
Pleas send comments to me about this AHA program.
And if you like to have this program in your own program, pleas 
give some mention about this AHA program and me in you documents. 
I my self find this program wery use full for selection in big data, or 
maybe only for presentation. And I think you other programmer do to!
And if you know how to have a nonaktive wait for key procedure, tell me.

    INT48 is posted at the usual site. If you don't know what that site
INT48 is a very comprehensive symbolic integration tables tool kit that
helps to find indefinite integrals.
Even more than that, INT48 gives you Laplace transform tables, Fourier
transform tables and Z transform tables.  However, this package is not
complete for it will be about 80k in size after completion.  INT48 will
also have add-on modules for various areas of engineering and so forth.
I will be happy to consider formula that anyone wants to send. Just tell
me the area of engineering or any other area of study and I will put
those equations with that category in the add-on.
Features of INT48:
1. User Defined integrals and the ability to store notes.
2. Fast and easy to read.
3. Displays formula as written on paper ( Java required for now )
4. Will solve equations for you in the future
5. Categories of INT48 include:
    All integration Types
    Laplace transforms tables
    Fourier transform tables
    Trig tables
    Geometry tables
    S.I. prefix tables
    and Much Much more.
Please let me know how this library works and how useful it is. Please
send add-on formula as well!

I didn't remember reading anything about erable in the manual.  Anyway, I
recently got a 128k ramcard and now have ASIM, which simplifies those

Does anyone know what the exact screen size in terms of the number of
pixels on the HP48 display?  Also does anyone know what ALL the
different annunciators there are above the pixelated area?  There's a
Left Shift, Right Shift, and Hour Glass for sure.  I think there's one
for the Serial I/O indicator, the battery, and a few others but again
I'm not sure.  Don't have my manual with me so I can't look any of it up

I had gathered from reading, mostly here, that the announcement for the new 

machine is anticipated this month, with the machine expected by mid-summer.  

Today I had to call HP tech support about a printer problem and, in closing, 

asked about the replacement machine.  My tech support agent said that they 
have 
been told that it is on schedule for summer of 2000, not 1999.  Can anyone 
confirm or deny?
This is not just idle curiosity -- my employer may develop a  set of 
programs 
for the 48 if the new machine is a year away, but if it is just around the 
corner we will wait and develop for the new machine.
Does anyone have more than a guess?
 
but that would be too easy... ;-)
 That's not a bad idea, though. A demo rom-dump right from HP, that would
allow you to key in problems, but you would have to buy the calculator
to get the solutions. And when they finally get the new replacement
calculator done, they could issue a beta rom dump for us all to test
that.
Seriously, the Emulator is a great little sales device. I became so
curious about it, that I bought a calculator (G+), Advanced User Manual,
and several of the Grapevine Books, which are quite good too, just to
learn how to use it.
Not only that, but I prefer to use the emulator for Erable and other
large programs that I am reluctant to load into my calculator, for fear
I won't have any room left, or I'll crash it and lose everything.

p.26   20.2.6   Diagram should show M not W
p.56   Program at bottom of page has *QUIT missing from listig before
A=DAT0 A
p.59   According to the tables C=DAT0 16 takes 17+16 cycles = 33
                                              C=DAT0 W takes  16+16 cycles = 

32
so the argument in the text about using 16 rather than W appears to be
the wrong way around unless the values in the tables are wrong.
Excellent document bye the way, I haven't quite finished reading it.
Keep up the good work,
 
32
I guess the values are wrong.. they are S/SX cycles to begin with,
but C=DAT0 16 and C=DAT0 W take the same amount of time on my GX.
(as verified with CTIM and JAZZ)
So I guess that will hold for the S/X as well.
 
Grrr!
There seems to be something completely wrong. Have you tried to install
ghostscript directly? 
In this case, forget it. The best way to install Ghostscript under Windows
is to get GSview from  http://www.cs.wisc.edu/~ghost/. Read its
installation instructions. It tells you in detail which files you need and
where to place them. The installation process of GSview then installs
ghoscript.
I've done this at least 20 times on different computers, it always worked
very well. 
end-of-line-signatures and other mess. 
First of all, there are many, many people who don't use word or even
windows. One can say many things about word, but if you try to share
documents you can absolutely forget it. Believe me, I get about
20 Winword documents in a year from all around the world, and dealing with
them is a huge mess. 
So Postscript is a very good choice. I you can't get Ghostscript working, 
then
I'm afraid you're alone in the world.

I still think text and Word are more accessable to most of the world.  I've
just been on the site you gave me a link to, trying to figure out what 
files
I need and how to install it.  I know only a little about unix and it's
ways.  It
made no sense to me after reading it.
I suspect that there are others in the same situation.
You're not. If you want a Word version, I'll send you one.
I don't have Word, but I can use the Word on my friend's PC
to do it.
I'm rewriting the whole thing. French first. English will come just
after.

Plain Text sounds fine as long as there are no figures, 7-bit ASCII
IS a standard. Word-format has the disgusting aftertaste of proprietary
formats which are complex and require you to use expensive software.
Of course, the problem with universal (and free ?) formats like ps,
is that there are many variants of it and people from M$ (to name
just them) will help all those variants to proliferate and try to
impose THEIR version (you might think of Java for instance...),
and you are back to the problem of application-dependant formating.
To illustrate this, my ghostview will digest about any ps-file,
except for those produced by M$-Word which tend to cause problems...

creation of a seperate non-english newsgroup would be better
for both the english only AND the non-english posts!
comp.sys.hp48 could continue on in english (pretty much as it
always has).  And a new group for non-english would encourge
MORE such posts, and they would not be quitting after a post
or two because of being flamed for not posting in english.
You can't stop the flames either.  Both the non-English posts and the
flames will continue.  That's the nature of unmoderated groups.
If you have an unmoderated group and you want it to remain unmoderated 
(and there are very good reasons for just such a practice) then there
is simply no point in making unenforcible rules.  You cannot enforce
them so they will be broken.  This is what happens in real life.
You cannot get the benefits and disbenefits of a moderated newsgroup
in an unmoderated newsgroup.  The language issue is something of a red
herring.  Somewhere, at some time, someone will write something in an
unmoderated newsgroup which you would prefer not to read, for whatever
reason.  Your only real recourse in such circumstances is not to read
it, using whatever mechanisms you have at your disposal.
Thinking out loud again:
There are two kinds of rules: proscriptive rules (which detail
what is forbidden, and what the punishment is for breaking them),
and descriptive rules (like rules of grammar or physics, which do
not forbid anything and cannot be broken, but which merely give a
succinct description of what is commonly observed).  When some of
us say that this is an English-speaking newsgroup we are merely
*describing* reality, not trying to legislate it.
To be perfectly clear: people on this newsgroup write in English
as a rule.  AS a rule, not BECAUSE of any rule.  See what I mean?
Some people dye their hair purple, but AS A RULE people don't.
I hope it's never legislated, however!  :-)
I tried to break the law of gravity once by jumping off a roof.
I didn't quite break it.  I *did* manage to break my arm, though.
Yes and I agree.  The problem arises when people confuse the
disinction between prescriptive and descriptive rules.  Attempts to
enforce the latter usually end in grief.
Been there, done that, eaten the pie :-).
My limited knowledge about this is that you'll need some
very small ML code to do this. Perhaps someone could provide
If no-one volunteers, let me know what you need exactly,
and I'll try to do it for you.

There are commands to compose and decompose 'composite' objects
like lists and Library Data objects, and more.
 
CHANGETYPE will simply replace the first five nibbles of the object
with the new type; since Library Data is a data object with a length
field following the type, you can only change similar objects to
Library Data this way (such as Code object, Array etc).
Now, almost the same question has come up a while ago, it was a request
to change a list into a Library Data object and vice versa, using the
format also internally used by the HP:
The # xyz is an *embedded* bint to indicate the library that's supposed
to use it, ob1 .. obn is what you really want to 'store' inside the 
LibData.
It is very important that you not use a ROM-based bint such as TEN or 
TWENTY.
Use # A and # 14 instead.
Here's the two programs that perform the conversion: (.ASC at the end)

At least on my hp48g/gx ROM revision M. Does it work on other
revisions as well? And on a sx?
 Yes, any HP48 version/model.
Well, you are surely entitled to your opinion!
But I feel that I am also entitled to mine!
And considering that a couple of MY programs are likely
included WITHOUT my consent...!
When programmers donate their time to furnish users with
good programs for FREE, then ANY PROFIT that anybody ELSE
makes off those same programs is simply WRONG (and likely
Now at $15 plus shipping, he couldn't be making a lot...
But considering that purely non-profit CD ROMs sell for
like $7 (including shipping and handling!), he is surely
making SOME profit!
Yes, he does have a nice web page, but that IN-NO-WAY entitles
him to make a profit off OTHER people's programs!
If he needs money to support his web site, then maybe he should
ask for donations.  But selling other peoples programs WITHOUT
their permission is simply WRONG!
. He is not selling programs. He is selling a copy of his site, and his work 

of:
1) collecting the programs that actually are free in the net
2) organizing them in the neatest way
3) burning the CD
4) sending the CD to you
The programs are free. The CD is not for it takes time and effort.
Nobody has to buy the CD against his will. If somebody buys it, OK for him!
Eric has the best site and what he is selling in the CD is a copy of his 
SITE!
IIRC it has happened that Eric was asked to remove copyrighted
material from his site previously, which he did graciously and
without any protest or arguing. If you feel taken advantage of
then, well, easy, just let him know and I'm sure he will abide
to your request.
But of course, this would be ridiculous. The time and effort
provided is such a great service that the, what, 1-5 bucks benefit
he might make per CD are pure joke and can be considered
as a means not to _loose_ any money, which would be utterly
stupid if you ask me. The fact that you can find CDs for
seven dollars does in no way imply that this is what it
costs him to produce his.
And think of the time involved in all the work HE provided in order
to make this collection as extensive as it is, and how much most of
us in rgg have taken profit of it. It seems to me like the time
he spends in compiling this collection is as good as mine when
I release some HP-soft.
This got lengthy, but picking on Eric for his work is really
out of place...
Almost all HP software is developed by users for users with no money 
interest.
I make small programs, which are in Eric's archive because I ASKED HIM to 
add
them. And I am so happy that he's going to include my programs in a CD that
will be used several times by users around the world. He can sell the CD if 

he
wants, since he has expenses to make the CD and to keep the site.
Eric,
you can place all my programs in your site and your CD without need of any
permission, since I know your efforts are not to lucrate but to help HP 
users
as me.
I daily use your site, and I think it is the BEST SITE EVER MADE FOR HP. 
Keep
on the good work...

Just a slight correction to the figures above: shipping is charged for
seperately, so shouldn't be included.
That not withstanding, and the views of one or two detractors aside, you
are under no obligation to purchase anything from Eric.  The CD is an
extra service that he offers along with his efforts in trying to bring
all of the information and programs for the HP 48/38/28 under one roof. 
I for one think that he is doing an excellent job, and hope that he
continues with it, although I doubt that he actually gets anything
financially back from it in the long run.
Could someone please explain the differences with all of these LID
ranges as I'm now totally confused, or alternatively give me pointers to
documentation of what the actual ranges are/can be used for.  [The FAQ
is too general to be of much use and I find some of the HP documentation
to be less than transparent.]

Umm, the 16th September 1964 was definately a Wednesday, I was there!  I
don't remember it, but I was definately there!
The error is that 16/09/1964 cannot be used as a system date by the HP. 
It will, however, accept this date in other calculations.  I.e. you can
put 16.091664 and a time on the stack and get back a string WED
16.09.64 ... .

The front (handle side) of the card says Hewlett Packard and Epson 
128KB
Ram Card for HP 48GX and has the proper handle on it. On the back it has 
the
HP logo, a note that says For distribution only with a new HP 48
calculator, and the CE mark with RAM48. Oh, it also has the proper 
shutter
for the contacts.
I wouldn't think that Epson would be able to use the HP logo without the
approval of HP, and I don't think HP would allow that without verifying the
function of the accessory. They're both pretty big companys, lawsuits would
fly!

I think using WINE emulator to use 48 emulator (!) isn't good idea.
It has to be slow, and WINE is still beta (if not alpha!) software, so
it would be not very stable...
it in English?... well, i do not like it!
M$ rather, don't You think so? :)
So XWin version is a must!
I've looked into code of x48 and emu48 recently and it looks, that emu48
doesn't have debugger (only disasm, ported from x48, by the way). ..
but on the other hand it is newer and faster and more flexible...
So I think the best solution is to create X version of emu48. 
Have to investigate it...
question
but know
The biggest difference between x48 and Emu48 V1.08 is the better emulation 
of
Emu48. That Emu48 is a faster is a nice feature, but not neccecary. If you
say this, because for the first Emu48 Service Packs I compare the x48 and
Emu48 sources as well. But there are several emulation bugs inside x48. 
With
my current beta of SP9 the Metakernel graphics editor now works perfectly.
When I run my test programs, I made in the last half year for testings some
hardware specifications, most of them will fail on x48 (most of them will
fail on old Emu48 versions as well ;-)=) ).

        I have put my revision of x48 at next site:
http://gaztelan.bi.ehu.es/~inigo/x48/x48-0.5.0.tar.gz
It's a ~680 Kbs., but I don't remember what is packed in it ;-)
I repeat it was coded using Gtk+ v 1.0.2, so don't expect it compiles
with current Gtk+ 1.1.12.
 Suppose I have a list of numbers, and I want to substitute each list 
member
into an equation. This will give me a second list. Now I want to create a
scatter plot from the two lists. The scatter plot uses a 2-column matrix. 
Is
there an easy way to get the list data into the matrix? Or should I be 
using
vectors instead of lists?
In my daughter's math class, they create a table of X values and calculate
the corresponding Ys from an equation. Then they plot the points on a 
graph.
Her class uses a TI-83, which can perform functions on lists and plot
directly from the lists. Not to be outdone, I tried to see how easy this
would be on my new HP-48G. I got stuck trying to get the lists into the
matrix.
 
When the TI-83 can do this we *have* to find a solution for the HP48
;-)
Hope I understood your posting correct:
You create a list, DUP it, perform the functions on the list you like
to do.
Then you'll have:
2: {...list 1}
1: {...list2 with the calculated values}
for this specific case (two lists to an array) you can create that
program:
 
functions. Once the lists are converted to a matrix and stored in a
variable, the matrix can be selected in the Plot data field.

For about 2 years ago I bought a HP OmniBook 5500CS (laptop) and on the hd 
there
was some different programs, eg. pim, and among other a HP12C emulator.

at erics site (look after emulators) or look at www.hpcc.org...

I disagree.
Hmm..  how do you mean overloaded?  Too many functions on one key or 
one
function works with too many different types (ie +)?  I don't think the 
menu
system is that bad.  I haven't seen menus with more than 3 levels.  BTW, 
try
alpha-purpleshift-DEL.
How long do you want your batteries to last?
I don't use the PC to program the calculator.  TED works just fine for me.  

The
TED included in the JAZZ package is wonderful for system/ml coding.
 
Yeah!  Something that has always bugged be is the fact that when working
with lists, the [+] key catenates instead of adding to each element in
the list.  Instead, you have to use that ADD function or whatever, which
is very inconvenient...  Why not catenate with some other function, and
use [+] the way all other arithmetic operations work??
I don't know...  I really use the catenation more than the ADD.  I guess as 

long
as you're familiar with the commands, it's not too bad.  I can think of very 

few
situations where I have to add a constant to every item in a list.  Just my
thoughts...
 
 
I'll address this question as best I can, noting that I don't my
SX here to verify timelines.
{ }+{ } was a concatenation process before Rev K.  During the G/X 
development we developed List Processing to its present state.
However, backward compatibility got in its way.  We had previously
defined [+] as concatenation for several object combinations.
If List + List were changed to something other than concatenation
then existing RPL programs would have been broken.
On the larger topic of keyboard overloading and useful commands
buried deep within menus, that's why the Custom Menu key,
[CST], is there.  You bring the commands you think are most
common into your own custom menu set.
 
You can get multiple solutions if addition were defined as addition. You
could have stored {-1 1} as s1, and you would automatically get multiple
solutions in your answer. Unfortunately it didn't turn out that way. Maybe
someone could make a algebraic evalutator / simplifier that gives multiple
solutions.....

-------------------------------------:: o
maybe on the next calc...they could have a flag, or set of flags so that 
the
user could set these sorts of functions and alternate commands to whatever 
they
thought were appropriately intuitive...???
 
Maybe the new HP can work in 6 idioms, like some Casio notebooks do. They
have functions in English, Spanish,French, Portuguese, Italian and German. 
It
is a little exaggerated, but possible.
I am of opinion that the new HP will follow the guidelines below
1 - it will make the new calc according to the technology available
Considering the available technology today HP will use it to make the new
calc.
2 - it will be done if it worths
A lot of things can be made but they doesn't worth.
for example, a piezo beeper with sound stereo,
it can be done but it doesn't worth.
3 - it won't violate rights nor laws
Many of the characteristics can be restricted due to legal restrictions.
It won't make  a new calculator with an IR that reaches 100 m, for example,
to avoid frauds in school tests.
4 - inheritance
The new calculator will have some of the characteristics of the calcs that
preceded it.
5 - French influence
The members of the ACO are French, so
it seems logical that the new calc will have many characteristics of French
programmers.
6-support
New HP will support HP48G/GX programs
Disclaimer
I don't know anything about the new HP, not even if it will come out.
I am not related with Hewlett Packard Company or anyother company.
I dont hear the writen above from other people, nor saw it in a page in the
internet.
The writing above is  MY OPINION ONLY.
 
You are right when talk about market, and how easy is to find batts in 
shops.
I remember Sony launched a Betamax system for home video, it was a tape a
more little than the format we have today in many countries. What happen?
even being best the Betamax, was taken over by the VHS, created by JVC and
the VHS become the tipe of tape used  for videos, and it get great part of
the market today.
The same happen with AA and AAA cells. Even being best, the batts like the
one used in cell phones, are not as easy to find and cheap than the AAA 
cells
available in every shop or pharmacy.
Today is not 1993, and you cant find LPs in shops, only CDs
and Sony become a TV station and a enterprise that make CDs.
Sony was forced to use the floppy due of they are available in the market.
Maybe the new HP will be forced to use AAA cell, even being the others 
best.
I am of the opinion that the new HP needs be updated to new technologies,
so
 I vote for new kind of batts like the one in cell phones.
By the way, I opened an HP48G and it has a SONY chip.
  Well, these goals aren't mutually exclusive...take, for example,
my Yaesu VX-1R handy talkie. It uses a high density Lithim ion
rechargeable battery, will run the radio for days on a charge...and
they also have an adapter that allows you to use a single AA battery
in its place (plugs right in the same spot)..the AA will only
last about a day or so in typical use...lot more power in
the Lithium battery...so people who enjoy the ease of use of
rechargeables are OK (that is, most people), and for the person who
is in the boonies, or needs to use it in an emergency, is able to
use easily available AAs.

You can convert text (strings) to GROBs (graphic objects) with the
real number 1 (small font), 2 (medium font) or 3 (large font). n=0 is the
same as n=3 except that for unit objects and algebraics you get a GROB
representing the Equation Writer version of it.
This GROB (Grob1) can then be added to another GROB (GrobTarget) this way;
GrobTarget { #n #m } Grob1 REPL.
The list in the middle is representing the offset from the upper left 
corner
of GrobTarget (n=pixels from the left and m=pixels from the top), and can
also be a complex number of the format (x,y) - then it's just dependent of
the current PPAR (if any).
An example:
Go into PICT and draw a circle. Exit the Picture environment with ON.
will leave a modified picture in the Picture environment for your viewing
pleasure. In the upper left corner of your previously sole circle you will
offset 1 pixel from the left and 5 pixels from the top.

that Port 1 is limited to 128k.  At a 128k device size, on a

the 128k device be seen at all times.  Thus, the cards run well in 
Port 1.  If Port 1 were made to accept 512k Byte devices, those 
devices would have to be broken into 128k chunks (or memory banks) 
and those chunks would not behave as nicely as the current design
allows.  Your favorite apps would no longer run well in either 
port!
I certainly do sympathize with the hassle of swapping out 
application cards.  If there is a workable solution, I expect 
I'll read about it here first.  Thnaks for putting forward an
idea for our mutual consideration.

Well, lets hope that what ever chip has been/will be chosen for the
calculator that replaces the 48* has an adress space larger than 512kB.
I don't know for certain, but there should be one out that that is
appropriate for a calculator.
 
How can i programm the seriel port like Out commands in UserRpl??
 
 oes anyone know where I can download a program to handle conversions
between binary, octal, decimal, and hexadecimal number bases? The
existing functions on the 48 seem a bit thin. I want to be able to
enter the number in any base and convert to any other.
 
this is a little mangled due to format problems...mac with various fonts to
but i have every confidence in your ability to figure it out...
if not, eep me...!

I'm not sure what you mean?
The HP48 has a lot of nice features to convert between number bases.
You just write e.g # 25d and then HEX, OCT or BIN and the number will now 
be
# 19h, # 31o or # 11001b.
What's the problem with that?

I found these books in a computer search. Does anyone know if they add much 

to
the more commonly available books and if so, where I can find copies?

    I have had a homepage on Geocities for awhile now.  Ever since the 
limit
was still 2MB, but have hardly had any visitors.  I have also been a
frequent visitor of this ng for awhile, but for reasons which I can not
fathom have never said anything about here.  Maybe I believed one day
someone would come across it.
    The page isn't much.  It's a first and small without a lot of content.
I have more programs that I haven't uploaded only because I was waiting to
programs or get my lame ass page off the 'net because bandwidth was 
precious
and my page wasn't worth the bytes it was stored as.
    The link to my page is http://www.geocities.com/SiliconValley/Bay/2680
Don't mind the name.  I changed my name awhile ago and never bothered to
redo the page because I barely have any visitors.  I hope that will change
soon:-)
    I was planning to add a little Shockwave Flash to the page.  Maybe for
the navigation and such.  Should I?  How many people like being forced to
download a plug-in just to find out that the page is sucky?  Granted the
plug-in is only 180k or something, but forcing is mean.
    I have spoken too much.  I have to leave on a three day family trip and
must pack.
 
In my opinion, you can improve your page a lot more, even without Flash.
First improvement: get off of geocities! They track you with cookies! They
have annoying popup windows! They have that annoying falling geocities 
logo!
Get xoom!

whether the page is sucky or not is irrelevant...
i just hate it that every 4th page i go to insists that i download some 
obscure
application that i need to view their page...!!!
i mean, what should a page consist of...text, pictures, animation and 
sound,
which is animation without the pictures...!!!
how many different applications are necessary, how many different formats 
are
necessary for displaying pictures...!!!
plus; i can never get them to work...!!!
i'm also cranky that aol's new 4.0 version incorporates MS Explorer into 
the
main application...!!!
like they've been totally brain dead for the last 3 years...!!!
and also, 4.0 is 30 ( THIRTY MEGABYTES ) ...!!! up from 4 Megabytes for

3.5...!!!
 
hi,
i've been using Opera version 3.xx as a browser for some time now, and
find it excellent. It is Netscape plug-in compatible, and downloads in
a mere 1 point 2  Megabytes. Their philosophy seems more in tune with
HP calculator types than either the IE or Netscape software team.

 Does the new HP take the card like HP48Gx ???
Some people have ram card or Rom car, i think is very important to make the
same card  and the same sytax to read this card 9or a emulator inside the

to read ... actual RPL..)
 
[snip]
I think a little clarification is in order. If there is a new HP (after
the 48G/GX) HP has not announced it yet. Therefore, any posts you see
here about the new HP are what people want to see, not what actually
is.

How about Erable with Speed Up?
Does it increases the speed enough as for notice it?
 
I have received some comments about the validity of the cycle counts in 
F.H.
Gilbert's Saturn tutorial which I have been working on.
However, I do not know which cycle counts are accurate.  Let's use ABIT=0,
for example.
In F.H. Gilbert's tutorial it says this instruction takes 7 cycles.  In the
Counts
by Dan Kirkland and Mika Heiskanen it says 6.0 or 7.25 cycles.
Sometimes all three agree, sometimes they are all different, and sometimes
two agree.  I don't know if cycle counts are different in an SX, so I'd 
like
to know if that affects it.
I would like to go through and update all cycle counts in the tutorial with
the *correct* counts, but I can't do that if no one seems to have counts
that are definitely correct.
Because the Kirkland/Heiskanen list is the most precise I'd assume it's the
know what I'll do.  Any help would be appreciated.
For the next week or so, please either respond to the group or
hard

All five G/GX keys that have nothing in green above them, namely
PICTURE, VIEW, SWAP, CLEAR, and DROP, perform the purple-shift

It may be usefull to add another shift key for other functiuns though.

 I have assigned the FASTOFF program to my off key. I am wondering if my 
hp48
drains more battery power after using FASTOFF than if it were turned off
 
it puts the whole machine to sleep properly and does not cause any
more power drain than a normal deep sleep.  Do not use the older
stand-alone FASTOFF programs, which eat batteries.
Good version: Library 1314, FSTOFF: By J-Y Avenard, 274 bytes,
checksum #8F12h.  Contains two commands: FASTOFF, and OFFASN which
simply assigns :: TakeOver FASTOFF ; to the OFF key.
If a new, better version than this has been written, please advise.
 I am probably missing something here. Why use FASTOFF? Can using FASTOFF
--  
You know how the HP48 usually takes an annoying amount of time to
turn on?  You want to perform a quick calculation, so you grab
your HP48, press ON, and then by time it's ready to use you've
forgotten what you wanted to calculate.  The more memory you
have, and the more libraries you have, and the more stuff you
have in ports, the longer it takes.
FASTOFF (better called FASTON!) puts the HP48 to sleep in such
a way that it turns on very quickly.  It's VERY VERY VERY NICE!
No heavy HP48 user should be without it.  Come to think of it,
skinny users might like it too.
Just make sure you use the lastest version, since the early ones
caused a battery-drain problem.  (Usually the battery in the

http://www.epita.fr/~avenar_j/hp/product/fastoff.html
I've not experienced any problems with it.  Has anybody else?
 
(possibly even the one you mentioned).
However, since you have a 32K HP48G, you might be interested in a
relatively small user program for standard TVM and Cash Flow problems:
Re: Business functions 1996/05/28
 
I would greatly appreciate information about
commercial sources for PC-HPGX cables and
software. I need to inform the users of some
special interest programs about where they may
obtain cables and software. Several of the German
companies offer cables, and KERMIT is of course
free, but I would prefer to recommend an
integrated package with good documentation such as
the HP Graphic calculator PC connectivity kit.
Cost is much less important than convenience in
this case. In the past, I could have referred
people to EDUCALC, but I am not quite sure what to
recommend now.
 Does anyone know of any good HP programming books.  I would like to 
buy
one that does a better job explaining the syntax and gives a lot better
examples than that of the HP manual.
 
http://usr.metamall.com/~cmnail/index.html
 
You could try HP's Advanced User reference manual, witch it should be
possible to buy almost everywhere.
I don't know the ISBN for i, but HP has listed it as part no 00048-90136
 
 
I am looking for a way to create a table of values such as this example :
For an equation y+AD0-x+ALI- I would have :
x          y
1        1
2        4
3        9
4        16
5        25
6        36
etc
 
how to make a function table is one of the Frequently Asked Questions.
Some solutions can be found at the FAQ (see the link below) in the
math section.
In addition John H. Meyers posted a nice little program to generate
function tables.
 Function Table Generator (like TI, HP38G) 1998/03/27
 
This table that TI have as a built in function,
I think must be implemented in the new HP.
This question is frequent. Are you having some test where need calculate
a table and make any plot of a function manually?:-)
You can make a table of values of a function using the simple prog below:
<<CLEAR
Enter values for X  { 
save it as a variable TABLE, for example, and run.
It must show a screen like this,
4:
3:
2:
1:{
You just need type
4:
3:
2:
1:{1 2 3 4 5 6
and press ENTER
to see the result as a list
{1 4 9 16 25 36}
Edit the equation 'X^2'if you need evaluate another function.
CMarangon
if you use an equation like X^2+X+5
instead of X^2 it works catenating lists innstead of summing the lists.
For example
It catenate the entered list and retun a wrong value.
if you enter {1 2 3} it returns
{1 4 9 5 10 15 5}. Absurd result!
so I mande another program using ADD instead of +
for {1 2 3 4 } it returns {11 19 29 41}
the correct value!
CMarangon
Try the library Mtools or just Itable which is a part of Mtools...
 
The costs of grad school have forced me to reluctantly part with my
HP-16C. This calculator is in great shape and comes with the original
slip cover. There are a few very minor scratches, but the display is
pristine and the keys work very well.

This is the third post I read saying Cynox cards are good.
I also agree they are good.
They come into a little box, with a (fotocopied?)sheet with

can see the Cynox cards dont look so beautifull as the others, but they are
cheaper and work well.

I've finally got a little more time to work on my UserRPL to SystemRPL
transformation utility, and require a little help with some of the
SystemRPL equivalents of the UserRPL loop structures.  Below I've listed
the ones I'm currently working on and what I take as being the correct
equivalents.  If someone who understands these better than me could
check them over I'd be in their debt.
Definite Loops:
START-NEXT / FOR-NEXT
 UserRPL           SystemRPL
  ...                    ...
xSTART              DO
xNEXT                  LOOP
  ...                    ...
START-STEP / FOR-STEP
 UserRPL           SystemRPL
  ...                    ...
xSTART              DO
xSTEP                  +LOOP
  ...                    ...
DO-UNTIL-END
 UserRPL           SystemRPL
  ...                    ...
xDO                          BEGIN
xENDDO                ...
  ...
NB: For anybody interested in this project, I've currently got something
that can transform simple programs into SystemRPL.  When I say simple I
mean programs that contain only: stack manipulation commands,
IF-THEN-[ELSE]-END structures, CASE-END structures, WHILE-REPEAT-END
structures, and a handful of the common math operators: + - * / ^ %MOD
etc.  Just enough ATM to prove that it can work, but not quite enough to
actually be overly useful :-)

How would I go about entering an equation that would allow me to enter a
function as a variable.  For example, I want to a write a slope equation to
memory and be able to solve it for a secant line of a parabola, sin wave,
etc.  I would like to be able to enter (X1, Y1) and X2, then enter
f(x)=sinX2 for Y2 in order to calculate m.  Am I making sense?  Please

I used a plunge-cutting Dremel tool bit (looks like a miniature end mill)
in a drill press rather than a drill bit. Neater holes and very unlikely
to damage the metal backing plate.
St216phane Grundschober, for the great instructions on how to do the 
upgrade
using SMD chips.
http://alpes.eurecom.fr/~grundsch/upgrade.html
I got my SRAM from Mauser electronics, p/n 551-431000AGW70L. They are NEC
SRAMs, 70 ns, NEC P/N UPD431000AGW-70L. They are $4 each, but they are
going down to $2.50 next month, so I asked them if they could give me the
lower price.
Here're a few other hints:
To solder the SMDs, took a piece of fairly heavy gauge copper wire, filed
the tip into a chisel point, and used some 30-ga. wire to bind it to a
blunt soldering iron tip. This gave me a mini-tip that made it a lot
easier to control the tiny connections.
I found that temporarily removing the blue coil next to the RAM made
soldering much easier.
I decided that the 3 wires attached to the second SRAM needed some
reinforcemnt to be reliable, so I added a little shot from a hot-melt glue
gun.
 --
Heh... I know what ya mean!  You've really got to focus doing those
mini-connections. Luckily, I only grabbed the wrong end of the soldering
iron once.  If I'd been smart, I would have called my friend who works in
the VLSI lab here at Georgia Tech and used their stereomicroscope... Owel.
 
Anyone have any experience connecting an IrDa compliant laptop with the HP
48GX.  If so I'd be interested in hearing how you did it. What protocol was
used, etc?
--
All began when all of a sudden, withotut any notice or explanation 
(no hit* at all) the screen of my Rev-R 48 GX (with two RAM Cards) 
went black and the memory from the calculator wiped out .... 
*I've been a HP rough calculator user since the 41 model 
(28 S, 48 SX and now this 48 GX), and know their reliability,
I can't explain myself what had happened.
Even though both my cards are from Digitalis (not GRiD), 
and changed (for the first time, since I got them last may)

I yet don't know which problem am I facing:
if it has to do with a broken card or a broken calculator 
but it seems it deals with this late one.
The Config Abort Program recommended 
(at Eric Rechlin's web site), was from 1992 
and for the SX model, and can't understand its usage
or how can it help me with this particular problem.
Even though I've taken away both RAM Cards, 
the calculator kept on the dark with a pair of vertical blanck lines 
...
I also left the three calculator batteries out (to let the main 
capacitor drain completely, as Brian Stone recommended) 
for a couple of days without any luck.
I'm desperate and believe had no chance ... 
at the idea of getting another brand new 48GX calculator.
And as the cards never lost their libs attached (memory),
I don't believe there is any problem with them, as long as
they aren't responsible for the calculator situation.
HP Argentina service is lousy, to say the least !
Expecting a miracle,
Carlos

Do you have any libraries attached to the Home directory?  There may be a
library configuration problem and you have to get a config
abort program from http://hp48.ml.org  Try to use that and see what
happens.  I ran into the same problems when I put a program into  my HP. I
thought my 1 meg RAM card was gone but it's o.k. now : )
Hope this helps; I don't want to see an HP48 user disappointed ; (
I will do all I can to help except buy you a new HP : )

____________________________________________________________
BEGIN_DOC cfgsupr_dm.doc
        A few days ago I got a library which conifg code crashes if no HP
EQLIB is installed. If a config code errors during a warmstart, you have
to hard reset the HP48 with the paperclip followed by 'YES'... I don't own
must be installed for doing this).
        Unfortunately I never saw a copy of the config aborter listed in
J.K.Horns library list (ID 14, IMHO the lib I needed), so I sat down and
following
config code:
%%HP: T(3);
::
 (The following CODE ob in HP terms:
  CODE
   GOSBVL =SAVPTR
   C=B    A       C[A] = R
   D0=C           D0   = R
   GOVLNG =PUSH#ALOOP
  ENDCODE)
 CODE 19 8FB9760D91341841428DC7530
 DEPTH {}N
 DUP ' ID CfgStk
 PTR 2E9E6 (SysSTO)
 INCOMPDROP DROP
;
This lead to two interesting things:
     1. During execution of a config code the stack contains a meta object
        made from library IDs (BINTS) of libraries pending for its config
        code execution.
        The meta ob looks like:
            #lowest_id ... #highest_id #no_of_ids
     2. Each config code is called by the sys-RPL routine starting at
        address # 2216h:
        ::  DUP
            ZERO_DO
                 IT EVAL
            LOOP
            DROP
        ;
        Somewhere in the warmstart code the meta object of all existing
library IDs is generated and #2216 is called; it pulls each ID and checks
the associated library for a config code; if it's present, it's called.
        With this information in mind I made the library below, a config 
code
suppressor. Its config code searches the home directory for the variable
'NoCfg', if it's nonexistent or don't contain a list (usally of real
numbers)
or a real number (which is internally converted to a list), no further
action
take place. If a library ID found in 'NoCfg' also appears in the meta
object
during config, it's removed from the meta object and the library is
attached
to the home directory. Finaly the code resets the LOOP parameters of the
#2216 routine.
        I gave this library the lowest unused ID possible (4), so no config
code of any moveable library have been executed when the lib 4 config code
takes over control.
        Below you'll find the source directory of lib 4 (along with the
currently working on it, I'hope I'll finish it next week).
Install/deinstall
it like any other library.
Where lib 4 is usefull for ?
      - If you get a new library, add its ID to the NoCfg variable to be
        shure it never gets control until you know what it do to your HP48.
      - If you have installed some noisy libraries (loud, long and ugly
        config codes), add the IDs to NoCfg.
      - If you want to take a look at a library containing a unfriendly
config
        code (copy/shareware protection or buggy) add its ID to NoCfg.
        Eg. If you copy the W&W Dis-Assembler (ID 1432 (reserved !) into a 
R/W
        port, you loose all memory upon the next warmstart ! Just add 1432 
to
        NoCfg.
On the other side there're libraries that *MUST* run their config codes to
work probably, eg.:
      - HP41 emulator. It messes up with the low-level port configuration.
        If its libraries are simply attached, it may crash the HP48 when
        trying to use the emulator.
      - Most config autostarts (eg. ID 1112) are useless if their config
        code is suppressed.
      - et c. (maybe somebody make a complete list ?)
Enjoy,
        8-Detlef

I've battled a similar problem with my SX.  I never did figure out what
the culprit was, but it was probably a software glitch of some kind. 
Taking the batteries out and letting the main capacitor drain completely
solved the problem.  It's definitly worth a shot.  You'll probably need to
leave the batteries out for at least a few hours.  You'll loose everything
you had on the calculator, but it's better than buying a new one.

I am using my 48 in my work, and both alg48 and Sune Bredahls SOLVESYS has
been extremly useful to me, thanks Mika, Claude-Nicolas and Sune.
I still miss one very useful and powerful routine: the AMOEBA, or 'Simplex
method of Nelder and Mead'.
Given an (mulitvariate) equation and a starting point as input, it will
almost always find a local minimum (quite fast, too.)
In most such situation, I would derivate with respect to each of the
variables and then solve the set of equations, either numerically or
analytically. some times that can not be done easily, and I would love to
have a fast implementation of the AMOEBA on my hp48.
If someone is interested, I think the code can be found on the net if you
search for AMOEBA and Nelder/Mead.
If someone allready has made it (sysrpl), please post it here.

 Objective: 
For money currency conversions, I would like to create a couple of user
units not based on a pre-defined unit as no one exist for currencies and I
want to take advantage of the purple-shift and green-shift functions for
unit handling. 
As the HP 48 manual says that all user units have to be based on a
pre-defined unit, I did the following:
1. I create one unit, let say Fr (franc) which while be regarded as a
reference. I base it on meter even if it is not relevant. It's just to
define it with a well-known unit. 1_Fr = 1_m
        1_m
        'Fr'
        STO
2. I create a new unit Eu (Euro): 1_Eu = 1_Fr
        1_Fr
        'Eu'
        STO
3. I setup the CST menu (purple-shift Mode Menu Menu) with the list {1_Fr
1_Eu}
As a result, conversions back and forth beetween both the units do not
work. I get an inconsistant unit error. I haven't figured out yet what I've
done wrong.

I have attempted to write a Battleship game for two HP48's. The graphics 
and
gameplay are working, but for some reason it crashes when one player wins.
Perhaps you would like to have a look at it? I would like to complete this
project one day, but am unable to continue with it for a few weeks.
Jeff Roulston
For some strange reason, there is much programs for the HP like last year.
(ie 1 year before) I remeber there was so much hype about MK and Erable
users going against ALG48. And we can't forget about WarioHP. There have
been many great programs, but now in the past 6 months, there haven't been
any good programs lately? What happen? Maybe Eric haven't been updating his
pages from all that busy work with other sites or maybe we are waiting for
that darn new HP that the Australian team is keeping a hush-hush on so that
we don't have to learn a new programming language. Is there any new 
programs
in development? I would like to see some new games, or new programming
routines. I think we should form a programming alliance where each team
member contribute together to make a fantastic game or something. I heard
about a game long ago about a game similar to Bust-A-Move in greyscale in
development which will be unveiled at one of those HP meetings.
Anyway I think we should form a programming alliance or something similar.
That would really rock the HP commmunity. TI has an alliance which they now
have a site underneath a .org domain. Just a suggestion.

Not all the keys respond on a HP48G.

done?
  Also does anyone know if there is a source of factory refurbished

This new challenge was inspired by the discussion at last Friday's
HP48 Programming Class.  (This is similar to the standard values
for resistors table, but just different enough to be refreshing.)
Imagine the interval from 10 to 100.  Divide it into several bins,
such that each bin's upper and lower bound lies exactly the same
percentage away from its middle value.  For example, two bins would
look like this:
|-------------|-----------------------------------------------|
|             |                                               |
|   1st bin   |                    2nd bin                    |
|             |                                               |
|------+------|-----------------------+-----------------------|
10     A                              B                      100
A lies in the middle of the first bin, and B lies in the middle
of the second bin.  The ABS(%CH) from A or B to the boundaries of
the bins (four values) are all equal!  Yes, the *gap* gets bigger
as you approach 100, but %CH from A to the boundary above A is
the same as the %CH from B to 100.  The answers for A, B, and the
percentage, for the above example, appear below.
CHALLENGE: Write an HP48 program as follows:
INPUT: n
OUTPUT: 2: { A B C ... }     list of bin centers for n bins.
        1: Percent           %CH from bin centers to bin boundaries.
For an input of 1, the output would be:
2: { 55 }
1: 81.8181818181
For an input of 2 (the example depicted above):
2: { 20.8113883008 65.8113883008 }
1: 51.9493853296
And so on.
*Mini*-challenge?  Not for me!  I spent several *hours* on it!

I think that this is perhaps the best way to own an HP49G without having
to worry about having an outdated machine.  As for your concerns about
posting the HP49G ROM for downloading, I'm sure they will come up with a
method of registration.  If I remember correctly, I bought my HP48GX and
filled out a registration card... the devices will probably have some
unique ID number or something that might be used to validate HP48G
owners (sounds like some Intel P!!! idea huh?).  Of course there will
always be ways around anything, but at least it provides some sort of
measure for copyright protection (assuming HP cares about stolen ROMS).
That's my hunch anyway...

Yes but it is not so trivial to implement this sub into the CAS so that
it can do it AUTOMATICALLY !!! 
The more automatic the CAS is, the more powerful its algorithms are.

=============
I rely on your input in order to keep this FAQ up to date.  If you have any
 
Really?  Details?  It doesn't appear to be in the user's manual -- is
this something for the Advanced guide?
I wonder if it's possible to do so accidentally..?  I guess, then, the
question is, how easy would it be to access flash memory with assembly and
could it be damaged by mistake?
-- The only way you could erase the HP49G ROM without using the internal 
system
command (that are protected and secure) is:
-Open your HP49 (it's closed as the HP48)
-Get the reference number of the FlashROM chip
-Go to the Flash manufacturer web site and find the technical referencs for
this chip.
-Close your HP49 (which is probably more difficult than opening it :) )
-Write a ML program knowing that your a Saturn ML guru as it is far more
difficult than everything that has been done on the HP48 before
How to modify the Flash ROM providing that you know everthing about the
Saturn, memory module and how a Flash chip works.
-Configure the hardware module in a very special way so you can use write
signal to the Flash (remember, the Saturn CPU doesn't have any write signal
on the module 0 (ROM), so you can't write on it. Once you've found out how
to do it, you will need to do an extremely particular operation to enable
the high voltage pin on the Saturn (it's not a Saturn instruction, but a
trick).
-Format the Flash ROM (64KB) by sending the right orders to the Flash (a
Flash ROM is similar to a small computer: you program it using special
read/write sequence which will configure the Flash for erasing. Then the
chip will send you back some error messages, information etc...
-Once the Flash ROM is formated, to write garbage on it, you have to do a
similar operation to the fomat operation, by sending orders to write 
special
nibbles.
That's it... you've corrupted your Flash ROM...
It took the ACO team more than a month to write the program above, and we
are quite experienced Saturn programmer...
To summarize, the HP49 Flash ROM is more secure than many protected RAM 
card
(as only HP approved RAM card as a real write protection, all the hand-made
one from Germany don't have any write protection so if you're machine crash
in port 2, your're stuck.)
Have fun...
 
All the flash memory modules I have had experience with are 
reasonably secure. In order to write to flash it must first
be explicitely erased. Flash memory is usually erased by 
'segment'. This means that an accidental write to a flash 
address would not corrupt it, unless the segment containing
that address has already been erased. 
Segments of flash are rather annoying in that they influence
the layout of code / data in the flash memory and may lead
to wastage in typical usage schemes.
Of course I have no idea what kind of flash device the HP49G 
will use.
 
I am interested in purchasing HP82240B 'Redeye' Printers. I only want NEW
units in original cartons with the external power supply. If you have such
want and the shipping costs. I will consider singles or multiples. 
   And I don't have an idea of what emacs is (could someone tell,
pls?), but I can confirm than in lisp, quote marks have the same
meaning as in the 48, that is, to delay evaluation of the quoted
expression. Difference with respect to the 48 (User-RPL) is that there
is no closing quote, as it applies to the expression immediately after
only.
   In the code posted above, the line
(autoload 'sad sad Disassembling HP48 memory t)
   invoques the (autoload) function with arguments 'sad [type SYMBOL],
sad [type STRING] Disassembling HP48 memory [type STRING] and t
[True, type BOOLEAN, IIRC] -- I guess sad is a function, and you need
to put a single quote preceding it so you're passing the _name_ rather
than its code.
   
in hope that they are going to run faster.
My problem is that I dont know how to use it. The documentation is not 
very helpful, so I need a short example how to do it.
sysRPL
My assumption (well, you know what assume does) is that you already
know how to program in SYS-RPL.  If that's the case, all that's needed
to be done is to write your source just like you would for GNU Tools or
HP Tools.  The only thing is that you don't need the header stuff.  To
compile your source (which is a string on the HP48), just put the source
on the first level of the stack and then type 'ASS' to compile.  (Don't
ask me why Mika chose ASS and not ASM for that command  name).
If you're just starting, here are some tips:
Use EC and press the right arrow key to disassemble the entry on the top
of the list.  This should give you some examples to work with.  Checking
out www.hpcalc.org might also help.
Good luck,
Han

which is only found in *compiled* algebraic
objects, and is not in the AUR.
Neither are xSILENT' nor xENDTIC in the AUR,
although they are right there in the
The decompiled user program above (per Jazz) is:
::          ( invisible )
 x<<        ( << )
 xSILENT'   ( invisible )
 ::         ( invisible )
  x<<       ( << )
  x'        ( appears as ' before a name )
  ID A      ( A )
  xENDTIC   ( appears as ' after  a name )
 ;          ( invisible )
;           ( invisible )
The above illustrates how the UserRPL compiler
(springing into action whenever you edit a command line)
hides lots of inner SysRPL stuff from the user,
much as one's skin hides the goings on inside one's body,
making life seem much simpler than it really is,
which perhaps gave rise to Einstein's observation that
 
There are 512KB of RAM dispatched as follow:
256KB of system RAM used for calculation and the execution of program (the
system use 13KB of this, the rest is fully available for the user)
256KB of RAM that appears as PORT 1 (works like a covered port on the
HP48GX)
2MB of Flash ROM where 1MB is already used by the OS.
1MB is left for the USER and works like a covered port on the HP48GX
(appears as PORT2).
The only restriction is that the files are limited to 128KB in a covered
port.
 .
 
   here we go -- I hadn't thought my routine (which I already use in
some of my programs) would stand a chance, but after looking at those
benchmarks, well it might be not all that bad.
<<
Checksum: # 3079d
Bytes: 40.5
Ticks: 4195 (Average of 30 runs using 1 RDZ {5 7} RANM as argument)
CPU Speed: 3.92
4195*40.5*3.92 = 665998 :)
 
 uh -- won't handle vectors :(
 btw, the above could be improved by replacing PILIST by EVAL * (but
still no vectors)
                   ^^^^^^
                           ^^^^^^
Unfortunately, the size of a vector is given as { n }, not { m n }. 
PILIST requires at least 2 elements in the list, from what I just tested.
 
 
Well, I got it down to 40.5 bytes, but it's slower than yours, so my
final score is 5025*40.5*3.75 = 763172.  I'll keep workin' on it.

Does anyone have any theory or hard facts indicating just when I might
expect to be able to purchase one of these things?  I already know what
it will list for and it's not too bad so I plan on taking the plunge.

If you take a look in the buying guide at www.hpcalc.org you will se a
list of companies that makes it possible to pre-order a 49.
BB-Marketing, which is one of them, will deliver them ( according to
their web page ) in august 99.

 After correcting the name of a Hack library command
a suggestion that to post UserRPL which can be
downloaded and stored into several different objects
all at once, you can also do this:
%%HP: T(3)A(D)F(.); @ Header line for HP48 Kermit
'name'
STO
[repeat: object, name, STO -- as many times as desired]
Then the above transfers into the calc as one single program,
which you can then execute, causing all the named variables
to be stored into the current directory, without any help
from any other program (some of my posts have used this style).
For SysRPL/ML, you can use (assuming Jazz):
%%HP: T(3); @ Next line defines a single string to EOF:
C$ $
::
 (some program here)
;
' ID name
xSTO
( etc. )
use it at work (other flavours of Unix too). But at home things are
different.
the
KDE Desktop and the StarOffice suite. Geeee! Setting the right properties
for me as user for everything to work fine was such a pain that I decided 
to
    Just my personal experience, but I am not really biased towards any of
the two.
     
what could be easier than this ??
     right-shift I/O                   (on the calc)
     ON                                (on the calc)
In your home directory, you need a file to set the defaults for the above
to work. It should be called .kermrc, and these work for me (most settings
here were found in some notes on kermit on www.hpcalc.org).
  SET MODEM TYPE DIRECT   ; (C-Kermit or Kermit 95)
  SET PORT /dev/ttyS22    ; (Or other communication port)
  SET SPEED 9600          ; (Serial port speed)
  SET CARRIER-WATCH OFF   ; (Don't require carrier)
  SET FLOW NONE           ; (Don't use flow control)
  SET PARITY NONE         ; (8 data bits, no parity)
  SET BLOCK 3             ; (if desired, or 2)
  SET CONTROL PREFIX ALL  ; (Necessary in Kermit 95)
  SET FILE TYPE BIN       ; (don't translate files)
  SET TRANSFER DISPLAY CRT ; (disable fullscreen status display)
You'll need to change the SET PORT line for your connections - for the
port that DOS calls COM1, use /dev/ttyS0.
 
Or just add such an option to the ED source.  It really wouldn't
be too hard to add a reformatter inside ED that works after ED
has been started.  And it wouldn't be very hard to provide a few
options either.
I cannot really do this as I don't have a home computer.  I do all
my HP48 programming on my HP48.  And this is not really an option
the compiled program, and then rewriting the final version into the
sources on a school computer.  And, it WAS a lot of trouble, even
if it was worth it!]
 
looked at its docs a bit more carefully - and saw the bit about the CUT
program this time! It does what I need to do, to wrap to the next line 
after
every 22 chars of the string - effectively chopping up one *very* long 
word.
Don't know if there is any other way to do this or not.
of viewing a giant no. from ALG48 without altering it ( as I only got my 48
recently, and am having a bit of a hard time getting to grips with it,
one-liners are close to my limit for 'programming' at the moment )
   Another handy little program, esp. for shorter no.'s, is John H Meyers
Tiny String Viewer at hpcalc.org (it handles strings of any size, but 'page
down' is really the only control)
   I'd quite like to do a routine sometime which converts a string to lines
which are a user defined number of characters long, but at the rate I'm
going, I'll get it done about 2030.......if I'm lucky!

The HP48 does not completely turn off when you issue the OFF command
(green-shift ON).  Your HP will sleep until you turn it back on.
However, there are 3 sleep modes (that I know of).  One is the DEEPSLEEP
which is the command that is invoked when you turn off your calculator.
Another is LiteSlp (#4912h).  I'm not sure what this one does.  It
doesn't appear to turn the calculator off so I'm not exactly sure what it
is used for...  The third one is to put the HP into coma mode.  I don't
know what the command is for this one, but it can be invoked by pressing
ON-SPC. Maybe someone could fill us in on the intricicies of coma mode..?
Anyway, coma mode suspends the clock and ignores alarms.  I remember
reading here once before (and I think this is in the FAQ) that the HP
draws a mere few nano-amps (nA) while in coma mode.
-- 
The HP documentation (HP49G user's manual) tells to look in
http://www.hp.com/calculator to get the HP49G Advanced USer's manual...
Or I didn't find it in their whole site...
Maybe it is not released yet ?
 
 A poster on a TI discussion group claimed that the HP48GX won't find
the antiderivative of x(sin(x)). This seems to be true. However, he
also claims that the HP49G won't do it, either.
Well, will it? 
The TI89/92+ will find this antiderivative.
And let's not have any TI flames, please - my HP49G is already on
order.
 Can you precise the function ?
x(sin(x)) sounds quite strange for me...
Not necessarily.  If X were an operator, eg X=d/dt, then F=X(sin(X))
would be
        F=d/dt(sin(d/dt))
That is,
        Fy=d/dt(sin(dy/dt)).
Or at least, that's what I recall from my brief experience in elementary
classical analysis.
I assume there's a version for user-defined variable of integration?
Also noticed something in the manual -- are matrices now allowed in
algebraics?  for that matter are matrices allowed in matrices (a route
for tensor algebra?)

    Somewhere in the information on the net about the new HP49, I 
   think I saw something about the expected lifetime of the Flash ROM/RAM
 It was is terms of cycles. For we computer hardware illiterates could some 

kind
person explain what a cycle is and how does this break down into an 
estimated time
most folks can understand. ie years, days, weeks, etc.

The HP48GX with big expansion card will be slighty slower than a HP48GX
without expansion card.
This is especially true when your turn off and off the calculator 
(sometimes
it looks simply tooooo loooog !).
Otherwise, if you have a lot of library attached, the compiler will be
slightly slower as there are more libraries to parse to check for the new
commands.
There's a big speed difference between the HP48G and the HP48GX/G+ as most
of the ROM in uncovered on a HP48G.
All the InputForm for example, will run nearly 50% faster on the HP48G
program

programmable
If by that you mean the HP is too slow to simultaneously sample and
compute, you might be correct.  However, a small independant unit can
act perfectly well as a sampler and temporary storage, from which the HP
can then retrieve unprocessed data and run it through whatever crunching
needs to be done.  To have the HP dedicated to the actual sampling of
data seems to me a waste of batteries.
- 
There are several programs that do this, one written by HP.  They don't 
talk
very much about it so that people don't copy the ROM cards.  One program is
Yes, it is one of them on hpcalc.org.  Joe Horn compiled his favorite 
programs
into goodies disks and made them available through different sources
(including EduCalc).
I don't remember which one it is on, so download the newest one (I think 
10)
which has an index that includes every disk preceeding it also.

Here's an English translation (did my best) of the txt file that comes
with ZeldaHP v0.48  I must say that this game is the ultimate see what
the HP48 can do program -- use this in any argument about TI vs HP in
games and I think the answer is clearly the HP.  Check out the demo, and
 
THE DEMOS ARE MAINLY TO DELAY THE TECHNICAL SIDES OF THE FUTURE OF THIS
PROGRAM, BUT IN PARTICULAR, FOR GETTING NECESSARY ENCOURAGEMENT FOR
FINISHING THIS DIFFICULT PROJECT.  THERE WILL BE A TIME WHEN THESE DEMOS
WILL NO LONGER BE DISTRIBUTED SO AS TO NOT DIVULGE THE GAME'S STORYLINE.
The keys of the demo are:
=========================
[ENTER] play
[4]     left
[6]     right
[8]     up
[2]     down
[7]     A button
[8]     B button
[DROP]  quit
=====================
24/05/99: ZELDAHP demo v0.48
        uncover them, even though I haven't finished correcting all of
        them... Lots of work planned on the PC to improve the editor
        and to be able to edit things easier..
23/05/99: ZELDAHP demo v0.47
        LINKHP's sword is no (whew :) usable in this demo.  I didn't
        imagine that it was as difficult and took as long to do, but
        now that it's done, I'm pretty satisfied with the result :)
        However, I'm still no totally sure that there are no more bugs
        as I had to make major changes in the game engine, notably that
        you need 14k free memory in order to start the demo.  The next
        beta will be the same as 0.47 but I hope with ** no ** bugs,
        othwerwise I quit!
17/05/99: ZELDA48 demo v0.45
        Added new structures in the main map:
        same..)
        + Horizontal scrolling improved
15/06/99: ZEDLA48 demo v0.44
        You can enter into the houses!  At the moment the interiors are
        all identical, but that shouldn't be too difficult develop.
        I hope to improve the hardware scrolling..
13/05/99: ZELDA48 demo v0.43
        Hardware scrolling implemented!
        (thanks goes to S. Cocqueremont).
        Small display problems still exist..
11/05/99: ZELDA48 demo v0.42
        The sign-related bugs are definitely fixed.
        + Incremental constants
        (I change only one address to port the addresses to RAM)
        Hardware scrolling almost complete..
9/05/99: ZELDAhp demo v0.41
        You can read the signs! Just go in front of one and press [9].
        + Source written ** entirely ** with constants :) (fixed
        entries?)
        + Created very dynamic algorithms
        Some optimization here and there, hardware scrolling next..
6/05/99: ZELDAhp demo v0.40
        Now LinkHP can walk anywhere in a world that resembles somewhat
        like SimCityHP..  But that's normal since it's just a demo.
        Still a lot of work in correcting the bugs and accelerating
        the horizontal scrolling (trying for hardware over software).
        Make sure to free up a lot of memory before starting the demo :)
29/11/98: ZELDAhp demo v0.32
        Optimization of code.  Menu option on hold since the game will
        change + rewriting of the 98% of the source using mnemonics and
        added a table containing all the ROM entry points used.  This
        way I can make a conversion to the S series for example..
        But I'm waiting for a better machine :-)
26/11/98: ZELDAhp demo v0.31
        I'm happy that I finally fixed a dumb bug that prevented us from
        talking in mariohp.
        + A new piece organized thanks to the power of modules!!
        + Now 80% of the source is written with mnemonics.
        The eventual porting to a new HP should be just as easy..
19/11/98: ZELDAhp demo v0.30
        Now the game engine is part of the module that contains all the
        data of the demo.  Possible for compression.
        + Corrected in the bug in the virtual armor.
16/11/98: ZELDAhp demo v0.29
        Dialogue box adapts to Link's position.  I still need to put
        all that in some order and you will soon be able to exit.
15/11/98: ZELDAhp demo v0.28
        I optimized the animations, the game is much faster.
        Now you can talk with two characters :)
        However the dialogue box covers Link sometimes..
14/11/98: ZELDAhp demo v0.27
        Many characters are ready to be animated by the new animation
        module.  However it still slows down the game becuase it has
        not been optimized.
13/11/98: ZELDAhp demo v0.26
        The animation module is quasi-perfect.  However it only handles
        one character at a time and needs optimization.
12/11/98: ZELDAhp demo v0.25
        I put in an automatic character animation module.
        For the moment it grinds horribly and I have only managed to
        work with princess Zelda.  She still doesn't look at you when
        you stand around her, which frankly is quite unacceptable!
7/10/98: ZELDAhp demo v0.24
        Now you can talk with the characters (finally!).
        Optimization of variables in creating modules.
6/10/98: ZELDAhp demo v0.23
        The character movements are almost perfect!
        The sprite animations are much prettier.
        + optimization of environment interaction.
4/10/98: ZELDAhp demo v0.22
        Menu bar much bigger and prettier.  The demo is in the form of
        a variable.
3/10/98: ZELDAhp demo v0.21
        The character control in further improved, (not always perfect).
        A presentation is added.
        Menu added and available with: [+/-]
        + debugging.
29/9/98: ZELDAhp demo v0.2
        Controlling of the character improved.  The dialogue box as
        well.
27/9/98: The first demo.
        This game is an RPG (Zelda-like) in greyscale.  If you like this

 I was wondering if anyone had info on how to use entries like
MULTF and aMODF and all the other math (add, subtract, multiply, divide,
etc.) elementary functions in assembly...  what must the state of the
cpu be, pointers, C[A], etc... so that these entries can be called?
 
I recently aquired an HP38 on loan and have been looking to see what
software is available for it on the web. I have not got a serial cable
for the HP38 but I have one for the HP48. I saw that it should be
possible to download software for the HP38 onto the HP48 and then
transfer it onto the HP38 with the IR. However when I tried this using
S38 I was able to transfer the aplets but not the programs that the
aplets need. Does anybody out there have a solution to this problem -
is there another transfer program for the HP48 that I should use to
transfer programs.
Also I read somewhere that System RPL programs may be transferred from
the HP48GX to the HP38. Is this true? What happens to commands such as
==
 
 
  I suggest a carriage return. This would be the right-shift key followed by 

  the [.] key. The assembly syntax you are using is MASD syntax and it 
requires
  that ALL source code strings end with a @ as the very last character 
in the string. So, for the last line enterthe @ char and NO carriage 
return.
  
  
 
----------------------------------------------------------------------
 ...
rom cards and put
Yes.  Ditto.  I am wondering the same thing. The information I've seen (at
www.hpcalc.org , thanks Eric!, good work) says something like: the entry
points have changed but it also says something like using  a cable 
between
the 48 and 49, and transferring the program in ASCII mode.  I would like 
to
know more.  This seems like it could be easy with simple programs, but how
will it handle libraries.  I have also run into problems with libraries 
that
I have down loaded conflicting with those in a ROM card--or just simply
conflicting commands (different programs with the same name).  I am nothing
like an EE or CS type, so it would be nice to know exactly what an entry
point is.
 
----------------------------------------------------------------------
 
I can't help you with the stuff about your cards, but I can try to help out
with the entry point stuff.
The ROM in the HP48 is like a big city separated into little buildings.  In 

one
might reside the command to add two binary numbers, in another might reside 

the
command to take the square root of a real number.  Each little building has 

a
separate address; for instance, if I remember correctly, the address of the
real number square root is 1F3B5.  Therein lies the problem: it's pretty 
hard
to remember the numeric addresses of these commands.  Compilers like JAZZ 
and
MASD make it easier for programmers, though, but letting us name these
addresses.  When you program, instead of typing PTR 1F3B5 (the pointer to 
that
building, telling the program to run whatever is inside it) you type %SQRT. 

When you compile the program (which is typed in as a string) the compiler 
runs
through the string and replaces all those names with the addresses of the
buildings.  It would replace %SQRT with PTR 1F3B5.  This PTR is known as an
entry point.  It's known as this because it does exactly that: it enters 
the
ROM at that point.
When JYA says that 48 programs simply need to be recompiled on the 49, what
he's saying is that the entry points may have moved.  The entry point for 
the
square root of a real number might now be at 2DD3A.  The address may have
changed, but the names did not.  You would just need to take your source 
code
(or someone else's source code) and recompile it.  Then the new compiler 
would
replace %SQRT with PTR 2DD3A instead of 1F3B5.  That's why you would need 
to
recompile on the 49.
Hope this helps,
Jeremy

digress for a moment; I noted a couple other current postings in the same
vein, which fall in the can I run my 48 programs on a 49?.  It would be
nice to have easy to follow methodologies for us non-EE and CS types, but
still like to try to tinker with things, to get our favorite programs
translated.
I've done FORTRAN compiling, but never came across  the need to change code
and re-compile except if there was a modified  'include' file.  The bottom
line is that I need to get more familiar with compiling in the HP48/49
environment--do you have any good advice as to where to start. The other
question I have is: Using something like the  COPY program by Rick
Grevelle (and well annotated by the guru -jkh- ), can I copy my beloved ROM
card to port 2 or 3, and then transfer it to the 49 using ASCII transfer?
The impression I have is that the 49 will recompile it and change all the
pointers.  Or, am I being a little to simplistic here and need to 
de-compile
it first, then do my transfer?  It looks it's time for a 'crash' course in
Hacker 101 (don't mind the pun).

have
Jeremy - if your program works as you've described, I'm very impressed!
One of the great weak spots in the HP48 ROM, and in ALG48 and Erable,
was the lack of ability to compute indefinite integrals that went
beyond very basic ones. It will be interesting to see how your program
performs. I look forward to downloading it from the hpcalc.org

I have had a look at dir_structure.gz on www.hpcalc.org, and RPLMAN and
have come to the following conclusions:
A directory (or more formally DORRP, or RAMROMPAIR Object) is structured
like the following:
                   +----------------+
                   +----------------+
                   |                |           RAMROMPAIR
                   |  ROMPART ID    |           Object
                   |    --------    |  Body
                   |    RAMPART     |
                   +----------------+
A Normal (where normal is defined as not the home directory with no Libs
attached) directory looks like:
(link_to_nth_object) (n-1th_object) (link_to_n-1th_object) ...
(1st_object)
eg:
DIR END
is: 69A20 FF7 00000 B6E5 == DORRP,7FF,00000,kcrc
This works great, and 0x7FF is the ROMPART ID, indicating there are no
libraries attached. When there is a LIB attached, 0x7FF turns into the
Library number. This is one of the reasons why you can only have one
library attached to a non-home directory.
When I go to the home directory, the inclusion of the hidden directory
makes things a little more interesting:
  BFF49 : 69A20           DORRP 
          200               | number of librarys attached
          200 74622 8D356   | ROMPART ID
          007 EFD22 00000   |
          A0000            offset for linked list
          00000            end of linked list
          00               Length of hidden directory name
          FF7              Here is a normal ROMPART ID 0x7FF
          C5000            length
          00000
         C
 BFF90 : 055375627B456973
 BFFA0 : 7E2342534C0E4A20
 BFFC0 : 55375627B4569737
 BFFD0 : 8047A20B2130E100
 BFFE0 : 06014C61627D6376
 BFFF0 : 047A20B213
                   000000
 C0000 : 0000000000000000
 C0010 : 0000000000000000
 C0020 : 0000000000000000
This is on a HP48SX with no libs attached just after a ON-A-F (Mem
Clear). The hidden directory is a nullnamed directory at the beginning
of the home directory. I assume that it should have an object ID of 00
(len of name), and the 0x02a96 DORRP, which is does.
The home directory starts at 0xbff4f, and has the correct prologue (
0x02a96 ), but I cant figure parts of the ROMPARTID:
 200             # Librarys attached 
 200 74622 8D356 # XLIB 0x002 , I think the second # is the pointer
 007 EFD22 00000 # XLIB 0x700 ,  into the Libs Message table, but
                                 am not sure what the first is?
Does anyone have any information on how to interpret this, or any more
info on
ROMPART IDs?
T I have a GX
No, I don't.  It doesn't seem to me to be much better than an
HP48.
In fact, I'll probably get flamed for this, but I much prefer
my HP-15C over my HP48.  The HP48 is just too bloated, too
inelegant, too slow.
 
    What I would do is to write my own program and start by using the get 
key
command.
I would then put those key press binary integers to a  list. Then, I would
decompose the list into its constituents and put those into a list. There 
you
are, your work all shown.
Now, when you start the program it has to wait for a special key press to
end. Therefore,
don't forget to tell the program to end when pressing the cancel key!  This
program will run until you press the cancel key!
Hope this helps!  - Jeremy L.
 Errata to previous message:
  63 SF is wrong should have been -63 SF
Keeping  flag -63 set slow the calc. down.  turn it off if you don't need
it. -63 CF when  you don't need it.
UNDO and LASTARG does not work.
Apologies for inconvenience caused
Gjermund Skailand
 
Well, you could juste type your calculus in a list, then make a copy of 
this
list by presssing ENTER and than see the result by pressing EVAL. You would
get something like this:
2:  {2 3 + 5 *}
1:  25

If you change only one of the commonly used RPL entry points, all program
will have to be recompiled anyway.
And anyway, there have already been a partial ROM modification when going
from hp48s to hp48g. I guess it wasn't easy to keep most user usable
entry points the same. Keeping compatibilty for the hp49 way have proven
to be too complex for what it's worth.
Actually they will be a way to convert automatically almost any binary
using only supported entry points except ASM. It's not that difficult to
do unless the binary is some kind of kludge spaghetti hack. And it really
worth the effor programming it. All we need is some internal info on
memory paging and a list of entry points in the HP49 with their
equivalents in the HP48. HP will likely release that soon (unsupported,
of course) because ASM and system-RPL programming ability is included in
the ROM.
Start here :
http://hpcalc.org/docs/programming/
Begin with system rpl tutorials, then assembly tutorials
If you get hooked you'd better go buy some book about system RPL and ASM
on the HP48. I don't know the good books on this topic in the US.
Finally, get the 2 ultimate obfuscated references: RPLMan and SASM.doc,
and the ultimate obfuscated programming environnement on the HP48, Jazz,
from hpcalc.org
 
Do the substitution x^2+3 = tan(y) first, then integration is trivial.
I hope the 49 can do it. My TI-92+ does it correctly almost instantly....I
grtow weary of the lousy TI-92 construction..I am hoping the 49 is REAL
good even compared to the functionality of the TI-92.
 
 
Since this doubts come frequently on this Ng, I decided to pour some of
my brains into electronic form, an this is the result:
THE HOW'S AND WHY'S TO THE HP48 LOBOTOMIZATION AND
OTHER MEMORY INTERVENTIONS:
This posting does not encourage anyone to do any physical manipulating
with their own calc. This posting may contain errors and any damage
done
to your own machine, room, school, anything you own (or don't), anyone
(including but not limited) to yourself, or your pet(s) is your own
responsibility.
I have no affiliation with HP other than owning some of their products.
This work has excerpts taken from The HP Journal August 1994,
whose copyright owner is Hewlett Packard.
Most of the knowledge (if any) expressed here was gained by reading the
Ng postings, on the comp.sys.hp48 forum, the hp48 FAQ, saturn.txt by
Matthew Mastracci and other more generic sources since Iâm an
electronics
student and hobbyist.
Please note: english is not my natural language.
INTRODUCTION:
The purpose of this document is to explain (some of) the inner workings of
the hp48 calculator regarding it's memory system, and how to use this
knowledge to perform physical interventions such as increasing main or
port memory, and why some memory devices (also know as ram chips)
work or don't, how to choose their size and so.
PART ONE
IN THE BEGINING:
I will assume that you know some electronics, like what is ram, ROM,
how
to use them, (that is: what do all of their pins do ;-) ), and that you
WILL
Hp
Journal, August 1994, and the Saturn.txt file, you might want to check
the
hp48 schematic, also available on www.hpcalc.org on docs/misc.
I will consider the Saturn as an 8-bit microprocessor, since it can be
seen as
such in hardware terms. Unless I say otherwise Iâm speaking of a GX.
Remember that silicon is dumb, it does precisely what the instruction
it
reads tell it to do, he doesnât understand them, or know if they are
wrong,
he just executes them.
To make sure everyone understands what Iâm taking about, Iâll 
start
from
ground zero.
As you know, inside your calc there is a chip called the Yorke, and
inside
of it lives the calc's processor: the Saturn. Well, this guy called
Yorke is
nothing but a bunch of Saturn support chips, shrinked into a single
small
chip. If you have ever seen the inside of your computer, you saw your
processor and lots of chips on the motherboard. Imagine that the Yorke
is
just like that, a motherboard for the Saturn. It has memory management
chips, Input/output chips, voltage regulation, timers, etc.
Let's pretend that when you open your calc it decompresses his insides
into
one such board.
You would see a Saturn processor, standing in front of you, impressing
ah?
It certainly has the Hp logo on it, but let's get to the point, since
this guts-
decompressing calc is designed for prototyping, you will find a
connector
on which you have access to all the processor's pins, and guess what?
It
doesn't look different from any other processor bus you have ever seen!
it
has nineteen address lines A0-A19, eight bi-directional data lines D0-
D7,
and a control bus, made of the following signals:Write Enable, Output
Enable, I/O/Memory Select, Maskable Interrupt, Non Maskable Interrupt,
and perhaps other minor stuff, neglected here.
Well, to me this looks like a Z80 or an 8088/6, give it or take a few
pins.
And because it looks so common (pardon the expression), weâre feeling
lucky today and are going to take our chance: yank it out!
AHHHRRGGG!!!! POKK! Geezz! They probably used some of the same
glue that the keyboard overlay has! But it is out, we throw it in the
air a few
times just to show off, hanging around the corridor, trying to impress
the
Saturn
processor before? Itâs way cool ha? to what they answer (being the
intelligent hp48 users they are), WOOOUUU, how did you get it?, then you
Say: I took it out of MY OWN calc, what do you think? but as they laugh
away down the corridor, you fall back to reality, and get back to work.
You stick it into a prototype board and say to yourself:
I want to run this thing on his own, what do I need?
Power: grab a power supply, set it to 4.5 volts.
A clock: get a 4MHz crystal oscillator.
Memory: ahhh!!! Since you are lazy, you get a 512Kb battery-backed ram,
with a PC connection, and fill it with a ROM-dump.
I/O: this would be a pain, so we connect our processor bus to the
conveniently located LCD controller connector on the calc motherboard.
Do the same with the keys.
Turn the thing on, and after the city lamps get back to full
brightness, and a
time delay, (you needed to get out from under the table), you see the:
Try to
Recover Memory prompt, you say no.
Now you are on top of the world, the thing works!!
You try 2 enter 2 + a 4 appears on screen, yes! It really works!
So you get clever, you write MINEHUNT enter.. PUFF, your screen
garbles, flashes and finally dies, nothing on screen, but you can see
from
the power consumption that the processor is still running, what
happened?
When you turned up the calc, it started at address #00000h, found that
what
was supposed to be system ram, at 40000h (half of addressing space) was
screen
display data area on what was before you upper ROM dump.
(Lower ROM goes from 00000h to 3FFFFh and from now on would be
referred as Lrom, upper ROM goes from 40000h to 7FFFFh and from now
on would be referred as Urom.)
Donât feel bad, to cheer you up, think that if you had a SX ROM dump 
it
would have been fine, since it only had 256Kb of ROM.
How to solve this? You need a way to put ram and ROM on the same
addresses, how do you do it? You choose to take the little steps
approach:
first get it working, then solve a problem at a time.
You need at least lower memory and some ram always present at and above
40000h, so you make a decoder that when A18 goes high disables ROM
and enables ram, and viceversa. You decide to make your prototype just
like a real calc, so you get rid of your 512Kb memory-backed ram, and
pick
a 32Kb one, and also pick the ROM from the calc and put it in the
prototype.
You turn the thing on again, get TTRM, say no, try the tests again, and
get
the same result on minehunt. What happened? a variation of what
happened
before, since minehunt is located on Urom, the calc tried to access it,
but
when it tried so, it read ram because your decoder makes it that way,
but the
chip is a 32kb device, it DOESNâT HAVE memory above 32Kb!!,
precisely, it knows nothing of what happens on lines A15 an above,
So it output what corresponded on the lines he has. Something pretty
random for our purposes.
Now you know: you need to disable ram again, after 48000h(half address
space+ram size), adjust your decoder, and assuming minehunt is after
48000h (might not be!), it worked!!
Everything seems to work fine, but you discover that some commands
crash your machine. You get an entry points table as see that they are
located on that tiny 32Kb block that you cannot access.
By now you want a G+ so you change once again the bb-ram and use this
time a 128kb device, set it in place and try it. Minehunt fails again,
why?
You have seen people upgrade their calcs just by replacing the main ram
chip, and they made no hardware modifications, you look again to your
circuit and feel stupid, there is no software on earth that can
overcome a
hardware restriction, like your decoder makes, or is there?
Well.. your decoder IS hardwired, the only one who can change it is
you,
using jumpers, wires or switches, but not by software, which would be
nicer. And this leads us to:
PART TWO:
Memory Controllers
Now you know that the calc has some way of disabling itâs hardware
decoders, and more, they are software controlled.
This looks complicated, a simple complementary decoder, that is, one
that
selects EITHER ram OR ROM is just that: too simple. Instead of trying
to
make one yourself, you look at the board and see 6 chips labeled:
Memory
controller 1 through 6, and you think: SIX!!!!, what do I need SIX
decoders
for?!, it goes like this: you need one for each device you expect to
have
connected to the bus, and since you need the ability to disable them,
itâs
better to have one for each device than sharing them, this avoids
conflicts,
adds flexibility and is in fact simpler to implement, since inter-
dependency
between devices can be made as a chain, by attributing them different
priorities.
The CPU bus architecture first developed for the HP71 and used in all
Hp
calculators since that time has several useful features. One of the
nicest is
its address configuration capabilities. All chips attached to the bus
are
required to be able to change, on command of the bus, the range of
addresses that evoke a response from the chips. Such a system
eliminates,
once and for all, the inconvenience and headache of configuring jumper
switches on cards designed to plug into the machine. For a consumer
product like a calculator this is not only a nicety, it is a necessity.
That says it all. But donât think that the memory controllers are 
only
useful
for systems with plug-in cards, as you can see it is also very useful
on a calc
without them.
So we have 6 memory controllers, one for each of the following devices:
Memory Mapped Input/Output,
System ROM
System Ram
Port 1
Port 2
Bank Switch
Each one provides a Chip Select signal, when the address on the bus
matches that programmed on it.
Plug the first two on our prototype system, and their output to ROM and
ram.
Now everything works fine, magically, the calcâs software is able to
disable
or relocate ram in order to access the covered ROM, it does so by
pushing system ram up, and increasing the addresses used by the Lrom.
All the memory controllers (mc from now on) have a default start
address
and size, so that when power is first applied there are no conflicts.
If two addresses overlap, however, the priority for which device
occupies the
Address space is: MMIO, RAM, Port1, Bank switch, Port2, ROM.
The ROMâs mc is set to 40000h (256Kb) size and start address is 
00000h.
The ram-mc is set to 20000h (128Kb) size and start address is 40000h.
Port 1 and port 2 mc size is set to 20000h (128Kb) and start at 60000h.
Mmio and bank switch are located respectively near the beginning of
Lrom
and near the end, at 80h and 3F800h, their size is 1Fh (31 bytes) and
800h(2048 bytes).
When the calc starts (I presume) it scans ram to check its size, if it
determines that there is a roll-over every 32Kb it re-configures the
ram-mc
for this size and the ROMâs-mc size to the full 512Kb. This is not a
problem, because the daisy-chain (priority settings) tell you that
ram has
priority over ROM when their addresses overlap.
If it finds a 128Kb ram chip, it leaves everything as is.
For the last 128Kb block of Urom the behavior is identical.
Letâs get physical!
PART THREE
Hands on
By this time you are thinking about getting extra memory on your calc.
When I say extra I mean EXTRA, which translated sounds like the guy at
the shop sold you something you didnât want, that costs a little 
extra
and
brings you no real benefit.
In practical terms you want more ram, lots more ram, loads of it, you
want
to use the so claimed 4.75Mbytes of ram Hp claimed it could handle.
Oh oh! What a surprise youâre gonna get. You have no chance to 
develop
your thoughts here, you have to do it THEIR way or you donât, period.
If you have a G+ or GX there are three ways to do it. Port 1, Port 2 or
both.
If you own a G, change your main ram chip to a 128K chip and go back
the
previous paragraph.
Letâs start from the G up.
You have 32K main ram, you want more, well.. forget the 64Kb chips,
this
size IS NOT SUPORTED by the calc, the calcs thinks itâs a G OR a GX 
not
a GFX (G frustrated expansion). Thatâs it, the OS will treat you bad 
if
you
do it. Besides it is not money wise to do so, since the 128K chips are
about
the same price. And IT WONâT WORK!!!.
You have now a 128Kb calc on your hands, call it G or G+ the only
difference is the keyboard overlay, nothing else.
So you own a G+ ha? You want more ram? Ok, letâs do it. After all, 
you
have been trying to give yourself a reason to open the calc.
Find a tutorial on the net. Do it. Done? After removing the overlay my
record is 34 seconds to get inside (calmly).
You want Port1 memory now, yeap, how do you do it?
You can only add 32. 64 or 128Kb on port 1.
Find a tutorial on the net, if you want to add 64 or 128Kb Port 1
memory
you DONâT need any other chips! They are only necessary for Port 2
expansions.
On most (all?) modern chips (that is: made on the last 4 years or so)
you
can connect the OE line to ground, to see if this is possible you have
to get
the data-sheet, and check to see if the WE line forces a high impedance
when low, if it does, you bought the right stuff if not, FIND ONE!
Connect the chip select line (positive logic) to the CE line on the
Port 1!
pads.
If you only have a negative logic CE line, (this is a problem if you
are
adding only 32Kb) you need to proceed as the tutorials for port 1 and 2
expansions explain and add the 74HC00(you donât need the other one).
Make sure that the tutorial you are reading powers the 74HC00 from the
main ram supply and not from the vcc at the port pad.
Complete, more detailed descriptions can be found on the net, remember
I
assumed you DO KNOW WHAT YOU ARE DOING, DO YOU?
Port 2 is nearly the same, except that you have to add a some-lines to
some-
lines decoder, chosen according to the size you are going to add and
the
number of chips.
PART FOUR
What about alien calcs?
Let me guess you are trying to put a 256 or 512kb ram chip on your calc?
No, no, no..
Better yet, you want to use that same chip for main ram, port 1, and
maybe
port2?
Looks like you didnât read parts one and two.
You CANâT!!! Well.. it is technically possible, if you are willing 
to
waste all the chipâs capacity above 128Kb.
Why? It goes like this: the hp can handle memory from 00000h to 7FFFFh,
right?
Letâs discard the 4 least significant nibbles. We get the last 3 
bits,
that is
lines: A16, A17 and A18.
A 128K chip has lines up to A16, a 256K chip up to A17 and a 512K chip
gets them all up to A18.
I assume you know binary, but here you have a resume:
Bin-Hex
000-0
001-1
010-2
011-3
100-4
101-5
110-6
111-7
The most significant(left) bit is the state of line A18, the middle is
the state of
line A17, and the rightmost is the state of line A16.
Now a little map of HP memory:
and see
how it relates to them)
000...001|010...011|100...101|110...111
0       128       256       384     512
You can see the changes of the top 3 address lines can you?
You can also see that a 128k device handles only A16, a 256k A16 and
A17, and a 512k device all three right?
Letâs connect your 256k device on our prototype.
(This time its me who hides under the table)
It is supposed to be 128k main memory and port 1.
In order to make the chip respond to both mc select lines, the one for
main
ram and the one for port1, you need to combine both of this signals
into
one, (itâs only ONE chip remember?), you need a circuit that goes low
when either of them is low, an AND or a XNOR gate would do it.
You can see from the graphic that the first half of your chip would be
addressed as main ram and the upper as port1, since the chip ignores
A18
(it doesnât have it). Minehunt works, you even store an object o Port 

1
and
it works. But what happens when you run one of the commands located on
the lower half of Urom? The calc moves the start of main memory to
responds
to the state of HIS lines and they tell him to read and write from his
upper
half, you say: wait! Wasnât that my port memory address space?!, you
are
right it WAS, now it has somewhere the results of the operation, if you
are
really lucky (this is highly unlikely) or it would have crashed because
it
read port memory instead of the data it was supposed to receive from
the
transfer area at main ram.
Something like this would happen with a 512K chip, the difference would
be that you waste the lower 256k of it and you get an extra way to
crash
your calc. This would happen the day you want to run some particular
game
or ML prog, that relocates main ram to 00000h, in which case you would
access empty space when relocating. (guess what happens. :-) )
This occurs even if you connect only the main or the port 1 chip enable
mc
to your chip, because it still responds to the address lines. The only
way to
use such a chip is grounding the A18 and A17 lines and using it for
EITHER function. Or for port 2.. (much better, and wiser).
PART FIVE
The end
I hope this helps (anyone) to understand the delicatessen involved when
you want to change something on the calc's brains.
Please note that I donât believe that if you could perform most of 
the
steps I
told you when building the prototype it would work. Itâs almost
certain
that several routines of both halves of Urom are used at start up, and
more
elaborated ram checks are performed making impossible for the virtual
calc
to boot. However all the issues I have addressed related to the memory
addressing are (believed to be) correct, if you accept that all the
calcs
startup routines are on Lrom, and minehunt is on the upper half of
Urom ;-)
However it is HIGLY UNRECOMMENDED that you remove your Saturn
processor from the Yorke...

Yup.  HP finally revamped the official (US) calculator website, and it has
the 49G on it now.  Check out http://www.hp.com/calculators for the new
page.
And with the new (official) English info, they have added their usual specs
list at the end, and IT DOESN'T DO FRACTIONS!!!  C'mon, HP!  How hard could
that have been?!?  It's in the 38...  It's even in the 6s for crying out
loud!!!

Perhaps you missed the specifics in my last post.  There are countries with
higher levels of firearm ownership without high per captia homicide rates.
This would seem to mess up your correlations.

Well that is the conclusion you hope for, but it is also not supported by
facts.  The highest mass murder in the US was done by gasoline, for 
example.
If you have an open mind, you may find the following interesting:
Several weeks after the Columbine tragedy, the air waves were still full
of tid bits on the incident. However, another mass school killing that
week barely got any local coverage let alone nation coverage.
I guess mass school murders are only news when a firearm is used. Since
school killings are the gun's fault, it's just not news if a gun wasn't
used...
It doesn't matter that this guy deliberately drove through a
preschool playground in an attempt to kill an exgirlfriend working
there. Fortunately for her, she was only injured. As were about 10
others; however I believe 5 were killed and one is still in a coma with
critical head wounds. But hey, a gun wasn't used; so it just doesn't
matter...  Neither did the deaths in San Diego when a car fleeing from
police lost control and drove through a playground killing several
kids...
Don't forget that gun laws increase crime.  Canada's strict firearm laws 
did
not prevent the shooting at
Southern Alberta high school.  Virtually no coverage was given to the 
school
shooting in Canada
just a week after Columbine.
Oh yeah, I think the Columbine shooters broke 22 laws including one that
says you can't bring guns to school!  If you're laughing you are missing 
the
point again.  Laws only change the behaviour of the law abiding.  There 
will
always be bad people doing bad things with guns.  The rate of bad things 
may
have something to do with the crazy, anti-morality, sneer at virtue, no 
true
heros any more culture we have today.  The answer is to have good people
good person would be armed.
Would you take guns from the police and the army, Jeremy?
 
I wold lonve to know these countries.
 How to make a determinant of a matrix done with symbolic values?
    Look in the HP48 Sofware Archive (http://www.hpcalc.org) for some
program that can do that, for the HP48 itself cannot do it.

  else find it?

: I was reading the HP.com web-page on the 49G, and came across the
: following:
:   [...]After all, in a text or exam, the answer is only part of
:   the solution.               ^^^^
Yeah, I read this too, and it really stuck me as being a bit over the
top.  It sounds like HP is directly suggesting that one will be able 
to use this calculator to cheat on a test.  A fine marketing idea,
but one which may not go over well with the big testing organizations.
This kind of thing is likely to make them wake up and reevaluate
their policies again.  I'll bet we see both the 49G and the TI-89 get
banned from a few more tests before too long.  The current anything
without a QWERTY keyboard that applies in several places is easy to
enforce, but it's no longer a meaningful distinction.
HP (and TI for that matter) better be careful, since I suspect that
a calculator which is banned on major tests might not sell quite as
well.

Since that publication's been unavailable for a while (as far as I know)
you might have trouble locating it but I think it would be your Rosetta
Stone so to speak.
If I remember correctly the HP41 barcodes were what they call Code39 type
barcodes. Searching for that will tell you the proper format of the
barcode but it won't tell you what numbers you have to encode in the
barcode (i.e. HP41 instructions).
If you can get your hands on the Wand documentation it came with a sheet
of paper that had many/all of the commands printed in really short
barcodes. It was kind of neat because instead of keying in each command
you could just read it off the sheet with a quick swipe of the wand.

it seems that the CPU is toped 22 or 23 micro second to read 22 or 23 bytes
from the memory (depending of the left margin) to refresh each line.
with a CPU running around 4Mhz, this is 88 or 92 cycles used to refresh 
each
line.
with 4096 lines refreched per second, it's 9% of the time.

You appear to operate a very nice web site related to the HP48.  
Today, I read a post where you stated that the HP48 ROM is on 
your site.  I confirmed that this is, in fact, true.
While I appreciate your efforts to assist the HP48 community, it
has been discussed quite extensively that posting of ROM images is 
not appropriate or legal.  Please remove the HP48 ROM file(s) from 
any web servers to which you have posted it(them).
Hewlett-Packard Company owns the US and International Copyrights
to this program.  As an employee of the company, I created the 
ROM image you posted.  As such, I have the right to request that
the Copyright be honored. 
In the past, posting ROM files has started a rather energetic 
argument, and occasionally a harsh message to the person who posted
the file.  I hope that doesn't occur in this instance.  I look
forward to many years reading your posts to the news group.  On

The only way to get the ROM is making a rom dump yourself.
The HP48G/GX ROM is protected by laws of copyright, and it is not available
in www sites for download.
I saw it one time in a site in Peru, but it was removed.
As we dont have warez site for HP48, you need use a ROM DUMP
and make your own ROM dump.
Try again, it takes about 40 minutes to make the rom dump.
( I dont know if it is permitted,but I think it isn't)

I have had the same problem with my GX about a month ago with the ON+A+F
working but would ask for recover memory then crash again, although
nothing at all happens now when I hit the on key or any resets. Tried 
pretty
much everything to no avail. I'm looking at a service at this stage, if
someone has had their calc serviced before I would like to know the steps
they took and problems encountered if any.
 
----------------------------------------------------------------------
 
        Why don't you try to take off all the batteries and leave the
calculator without them during a day. This will clean all your RAM memory
completely. After this, try again to put the batteries.
        Other solution would be to change your batteries. Maybe they're
empty. ;) 
----------- 
I had a problem, yesterday I turned on my HP48GX and apeared an 8 in the
command line, and apeared the display very dark (with the contrast very hi)
and thats all, it doesn't respond to anything, on, on-c,on-a-f, only to the
reset button that in shut-down the calculator (does not display the mesage
try to recover memory?), then I took out the batteries to clear all the
memory and  hour later I put them on again, and now ever time I put it on I
have different things, sometimes what happend last time, sometimes puts 
some
vertical lines in the display, always stops responding and I have to use 
the
reset hole.
Some sugestion?, know what it is about?
thanks in advance.

Here's another oddball newbie question for you HP48 experts.
By convention, zero degrees in a polar coordinate system lies along the
positive X axis, and positive angles are measured in a counter-clockwise
direction from the positive X axis. That doesn't work well if you're a land
====
====
You don't have to. It's a matter of getting the conventions right.
If the polar-rectangular transform on the calc. is:
(Dunno what it looks like in HP-speak - I use TIs, and I only come in
here for the Frog vs. Redneck language wars and the odd surveying
thread), then if you take (X, Y) as representing (North, East) rather
than (East, North), and resolve to measure angle from the North- (now
the X-) axis clockwise, and the hell with the consequences, angle
becomes azimuth, and
< 0 Then Azimuth = Azimuth + 360 after the transform, as usual.
To get a feel for this, sketch the axes in the East = 0, anticlockwise
convention on thin paper. Turn the paper over, and swing the X axis to
North. You're looking at the same sketch, but now, as if by magic, it's
illustrating the North = 0, clockwise convention.

[ LaPlace Transforms in TI89 and HP48 compared by Perez-Franco ]
I've developed a way to solve LaPlace transforms in my new TI-89 (presented
below) and I wanted to compare its speed and performance with other 
proposals
for LaPlace I've seen.
In HP48GX, we solved LaPlace transforms using the great program by Bernard
Parisse: Erable (ver 3.1). We used z LAP EXPA.
In TI-89 we used three ways:
1) First LaPlace proposal by P216rez-Franco
-¤(e^(-s*t)*z,t)|t=0
using 20 bytes.
2) Second LaPlace proposal by P216rez-Franco
-limit(¤(e^(-s*t)*z,t),t,0)
using 27 bytes.
3) LaPlace proposal by elrond
using 23 bytes.
Answers were verified in MapleV for accuracy, using the following line:
In all these lines, z is the function which we want to transform and 
¤ is the
integration symbol.
Let's check out the time it took to solve the LaPlace transforms of some
function using the different tools.
Function 1): 1
HP48GX+Erable: Less than 1
LaPlace P-F#1: Less than 1
LaPlace P-F#2: Less than 1
LaPlace elrond: Less than 1
Function 2): 3*sin(5*t)
HP48GX+Erable: 5 sec
LaPlace P-F#1: Aprox 1 sec
LaPlace P-F#2: Aprox 1 sec
LaPlace elrond: Aprox 1 sec
Function 3): 1+t+t^2+t^3
HP48GX+Erable: 5 sec
LaPlace P-F#1: Aprox 3 sec
LaPlace P-F#2: Aprox 3 sec
LaPlace elrond: 45 sec
Function 4): 2*sin(2*t)+3*sin(3*t)+4*sin(4*t)
HP48GX+Erable: 16 sec
LaPlace P-F#1: Aprox 3 sec
LaPlace P-F#2: Aprox 3 sec
LaPlace elrond: Aprox 3 sec
Function 5): 4+3*t^2+cos(5*t/3)
HP48GX+Erable: 9 sec
LaPlace P-F#1: Aprox 2 sec
LaPlace P-F#2: Aprox 2 sec
LaPlace elrond: Didn't finished in 6 minutes...
Function 6): 4*t*cos(3*t)
HP48GX+Erable: 6.5 sec
LaPlace P-F#1: 6 sec
LaPlace P-F#2: 7 sec
LaPlace elrond: 48 sec
Function 7): 4*t*cos(3*t+Pi/3)
HP48GX+Erable: Gived wrong answer, -2/s^2.
LaPlace P-F#1: 20 sec
LaPlace P-F#2: 22 sec
LaPlace elrond: 80 sec
As we can see, in speed and performance, the best proposal by now is to 
solve
LaPlace transforms using -¤(e^(-s*t)*z,t)|t=0 . I suggest using it 

as a user
defined function called lap() which can be done by typing in your TI-89 
this
line:
Define lap(z)=-¤(e^(-s*t)*z,t)|t=0
Comments are welcome to hplus@i.am

sci.math:275801
It seems to me that you are comparing apples and oranges (for speed) 
since on the TI the laplace's transforms are being calculated from
its definition via integrals which are a lot more processor and 
memory intense than by using the standard laplace transforms tables.
Get a custom made laplace transform program for the TI or also
use the integral definition on the HP to fairly compare Laplace's
Transforms speeds.
Carlos.
----------------------------------------------------------------------
Carlos...
In my university, you can have oranges or apples for lunch, and teachers 
don't
care at all. That is your preference and you can eat the one you wish, or 
even
both of them.
Equally, in class you can use TI or HP and teachers don't care. For them, 
TI
and HP are just calculators, equal calculators you can use in their class.
What I am looking for is THE FASTEST way to solve LaPlace and InvLaPlace in
my classroom in my University. I don't care for processors or brands or 
chips
or algorithms (although I made a very good one for TI). I just care for 
speed
and reliability, wich are the two only factors that really count in middle 
of
a math exam.
:o)
P.S. Maybe they are pineapples with bananas.
====
sci.math:275938
Perez,
Ok, so why don't you compare speed and reliability BUT use the following TI
program designed to perform Laplace's transforms ? Let me know which one is
THE FASTEST and most reliable package.
The program package DiffEq92 contains functions
for LaPlace, inverse LaPlace, solving single and
simultaneous differential/integral equations with
constant coefficients using LaPlace. The package
can be found in the Ti-92 archive:
ftp://ftp.ti.com/pub/graph-ti/calc-apps/92/
Carlos.
----------------------------------------------------------------------
----------------------------------------------------------------------
Carlos,
don't you think that the TI software called Laplace92 is kind of a good 
choice
for doing LaPlace ?
Well, that is exactly what we used in our last comparation (the third)
published here a couple of days ago.
====
sci.math:276185
All I am saying is that there are several math programs for the HP but
we all know the two best ones. Now there are several laplace programs
for the TI, pick the best one for comparison (since you did pick one
of the best ones on the HP).

comparison (since you did pick one of the best ones on the HP).
I am pretty sure that Erable 3.2 is the best for HP, since I've personally
tried all the others and no one compares with it.
About TI, I can't be so sure, because I don't have my cable yet. Now, I 
think
that a program which name is Laplace92 should be pretty good to do, let's
say, LaPlace transforms. And that is exactly the program we (the other guy 
is
a friend from another country which does have a cable and does have 
Laplace92
and knows how to use it) used to do the last comparation.
Now, when I receive my cable (which will be in a month or so) I'll 
personally
try out the program you suggested and compare it with Laplace92.

How do I write this function in Erable
====
sci.math:275731
There is (currently) no way to find the laplace transform of
delta/heaviside
functions (I have only implemented inverse Laplace of polynomials using
delta functions)
LAP should return the unevaluated integral.

By the way, Bernard, what are these libraries that come with Erable 3.2?
Geo.lib (geometry?)
Lin.lib (linear algebra?)
Modulo.lib
Prep.lib
====
Geo.lib is for differential geometry (or many variable functions as you
like).
Lin.lib for linear algebra
Modulo for arithmetic
Prep.lib mainly for hacking it includes internal objects arithmetic
operations
and conversion functions.
You can install these 4 libraries everywhere.
Mainly for erable.lib, some functions of the 4 libraries might be
documented
as well

Great! I haven't noticed that you had released the new version. I'll 
install
it this afternoon in my HP and the HP of my friends.
Hey, Bernard, Erable is great... thanks!
A question... does the new Erable solves this LaPlace transform?
====
sci.math:275382
So what?  I'm sure the TI89 is faster than the HP48 at almost everything!
However, the HP48 is at least 8 years old and the TI89 is less than one.  I
think that's pathetic, someone who buys a TI has to wait 8 years to buy
something that beats the HP.  That's not completely true either, 
considering
many people, including me, still like the HP48 over the TI89 (I've used the 

TI92
for a few weeks) and the HP can still do many things that the TI can't.
Anyways, the HP calculator is a solid investment, and when/if HP comes out 
with
a newer version, I'll be investing in 2 of those as well.
----------------------------------------------------------------------
        ..
OK, how about _inverse_ Laplace transforms?
The HP48 with Erable does that.  I have not determined how to get the
TI-89 to do inverse Laplace transforms as of yet (I had found the
first two method of doing Laplace transforms on the TI-89).

InvLaPlace is HP's territory.
I've heard that there is a program called Laplace92 that makes InvLaPlace 
in
TI89. But that requires a cable and mine is not here yet.

So it is good to know how and where to do the fastest LaPlace transform 
(not
to mention that there are functions that I have not been able to transform 
in
HP and that TI have made with no problem at all).
So am I.
I know that.
something that beats the HP.
That's why I bought HP in first place, two years ago, and then another HP 
one
year ago, and just until now, when TI have something good to offer, I buy 
TI.
Always the best.
Including me, too.
I can mention a lot. HP is more flexible. HP is more programable. HP is 
more
expandable. HP is easier to transfer info with PC. HP is better in a lot of
features. No doubts on that.
That's why I have two HP's.
I will buy one, too.
I think the comparation I made is a good thing to know, and you can bet 
that
I'll make all LaPlace transformations in class using TI because it is 
better
than HP in that specific skill. But HP will still be used for the most of 
my
things. Because I use the best in each area. Where TI is better, I use TI.
Where HP is better, I use HP. Where Casio is better, I use Casio.
And that does not mean neither that I do not understand the differences
between both of them nor that I am a blind fan of HP or any other 
calculator.
I just use the best I can afford for each case.

HP: 74.6 sec
TI: 79.1 sec

Both gived different answer display than MapleV.
 
Just out of curiousity, the HP now does LaPlace transforms better than the
TI89, so what do you use the TI89 for now?  With Alg48 and Erable 3.2
installed, I think the HP has the TI89 beat in almost all areas.

The problem is not the HP48 - instead it relates to numerical analysis.
The condition number of this matrix is very high. Any method you use
will
be subject to rounding error. This is not a problem with the HP48 per
se, 
but rather a problem with what you are asking for. Floating point
numbers
are messy things. 
To check the condition number, use COND. If this number is bigger than 
====
The problem is in the matrix itself.  It is not well conditioned,
which means that although it is not singular, it is close enough to
cause numerical problems when inverting.  Check this out with the
command COND.  Small numbers mean the matrix will behave nicely when
inverted (the identity matrix has condition 1, and it's inverse is
itself).  Large numbers mean you might have problems.
On the other hand, Matlab computes the correct answer, even doing an
inverse and multiplication, instead of something more intelligent,
so I'd guess it has something to do with precision.
Other methods of solving the matrix might yield better results, but
LSQ didn't seem to help any.  Maybe there is a library to do this?
When you really think about it, the answers are only off by .04
percent.  If you need better accuracy than that for this particular
application, maybe use a different tool.

that. If you examine the programming, the word elegant doesn't come to
mind, although brute force does.  <-- not a joke
  Still, it's tiny and it works.
First, store the desired test values as global variables. Put the
symbolic matrix, which must be 2 x 2 or 3 x3, on the stack and run
EVALM. The symbolic variables will be replaced with the stored values.
Use UNDO to change the matrix back to symbolic again (or dupe it first
to save a copy on the stack).
Example: let's say the 2 x 2 matrix has two unknowns, R and r. Store 2
into R and 3 into r. Put the matrix on the stack and press EVALM.
  2R/r  -r              1.333...  -3

This is the first unofficial lick of information that they are
working in a new HP calculator and it will be far better and faster
than the TI89.

resolution when I am doing FEA calculations or a structural analysis, I 
just
want to be able to read the calculations without having to squint.
Up to 4 megs of memory in the HP48GX as compared to 500K max in the TI-89!
Please feel free to list some functions that can be performed on the TI-89
and not the HP48GX.
Faster?? The processor may be faster (10 vs 4), but that didn't help me

Don't get me wrong - I'm a loyal, diehard HP user. My HP48 is my first 
weapon
of choice. However, the computer algebra system of the TI-89 is awesome! 
The
TI-89 can do almost any symbolic derivative and integral. It instantly
computes any integral numerically, including double, triple, and improper
integrals. The HP48 is hard pressed to compete. Erable is a terrific 
program,
greatly increasing the basic symbolic program, but even Erable fails on
certain types of integrals. Symbolic and numeric dif.eqs. on the TI-89 are 
a
snap. 3-D graphing on the TI-89 is easy and fast. I'm studying Intermediate
Calculus now, and I use my HP48 at school where the TI-89/92 is banned. But 

I
use my TI-89 to help me with my homework. I must tell you I genuinely 
dislike
using a TI. I'd much rather use my HP. But HP currently has nothing to 
compete

And the GX is expandable to 4 MB. The TI is not expandable at all.

handheld out there.

it here anyway.

to

After 3 years of owning the HP48GX, it is no longer functional. I am not
impressed!! I have used it for university only and treated it very well. I
have been searching for a support/service site and phone numbers in
Australia, but to no avail. I would like some suggestions to what steps I
should take to replace or repair my calculator.

I'm sorry your experience has been frustrating.  I went to the 
www.hp.com web site and found HP Calc customer support numbers
listed at
http://www.hp.com/calculators/service/product_support.html
Of course, true to the HP Way, I dealt with dozens of Java Script
errors to get there (I'm using an older version of Netscape).
The support number in Australia is listed as:
        +61-3-9272-8000
I will presume you have tried the commonly-listed ways of kick
starting an HP48 or checking for problems, such as:
- There are reasonably fresh batteries installed, with the middle 
cell oriented backward from the two end cells.
- You have removed any installed cards.
- You have not modified the insides of the machine or, if you have,
you have closely scrutinized all solder connections with an ohmmeter
and optical magnification.
- You have pressed the RESET button hidden under the rubber foot.
- You have placed its lifeless form on an altar made of archane
math textbooks while a priest, a rabbi, and a druid performed
miscellaneous rituals involving obscure herbs, potent beverages, 
forgotten languages, and one rubber chicken.
Try these first.  If they don't work, and you decide the existing 
machine is simply an undersized fishing anchor, you might enjoy
opening the poor cadaver using the instructions listed for doing
memory 'upgrades' out on the net.  Once the box is open, look to see
if there is something obviously disconnected or fractured.  If
you find it and fix it, all's well.  If not, you've lost nothing in
the attempt.
Best of Success!

Wich serial port is used when
you send data ?
Is it possible to choice the serial port ?
How to see which
data are sent ?
Is it possible to make dialog between 2 Emu48 by serial line

what size does the rom dump have ?
 524.288 Bytes would be GXDump (and similar) output
1048.576 Bytes, the double, what CONVERT brings you
(this is valid for G, S rom files are half of size)
So run Convert on your image, and maybe you get it right

Uh, most shareware distributors do get permission from the
authors before they SELL such.
I have NO objection to anybody providing my programs to others
for free!  And I have never said otherwise!
I DO object to someone SELLING my programs WITHOUT my permission!
Which is what I have been saying all along!
No, even deliberate uploads does NOT constitute a release of
copyright.
I have NO objections to anybody USING my programs!
And I don't object to people being able to download my programs
for free!  But when ANYBODY starts SELLING MY PROGRAMS WITHOUT
MY PERMISSION, I DO OBJECT!!!

Sorry John, but while I would like to say you misunderstand what
I have been saying or such..., I KNOW you read better than that!
And as I have been saying that he shouldn't be trying to make a

So, what is YOUR point!

Then do what others have suggested. Police your own programs and leave

Well, first of all, selling programs WITHOUT permission from the
authors is ILLEGAL!  There ARE laws to prevent just this sort of
thing!
I am VERY suprised at how many are not only willing to overlook
this, but are actually willing to SUPPORT his ILLEGAL actions!
I don't know the guy, so I cannot say if he is a nice guy or not.
But being a nice guy does NOT make it okay to break laws!
Many have said that he has a great site, and that he is doing
the HP48 community a great service with it.  But again, this
does NOT make it okay to break the law!
Now most the stuff on his site was intended to be shared.
And it is indeed a good thing that someone is willing to put
together a site to help with the sharing of these programs...
As long as it is free.  But doing all this does NOT entitle
that same person to SELL these programs!  Doing such is
Also, this is NOT the sort of thing where one can say it is
okay for this person to do, but not someone else.  If it were
okay for one to sell these CDROMs for $15 plus shipping, then
it would be okay for ANYBODY to sell such CDROMS for $15 plus
shipping!  But it is NOT okay for a person to try and profit
Most of the world has copyright laws to prevent just this sort
of thing!
I have been asked by others if it would be okay to include some
of my programs on a CDROM.  And I told them that I was NOT
interested in having my programs on any CDROM intended to be
sold.  If I were now to overlook someone doing exactly that
WITHOUT EVEN ASKING, I would be doing a BIG disservice to those
who did ask!
I feel it is my right and my DUTY to disscourge such actions.
Even to the point of taking legal action IF NEEDED!

----------------------------------------------------------------------
you personally. I only try to help you understand why many (if not
most) of us don't are against a copy of hpcalc.org on a CD-ROM:
That's right, but I doubt Eric is selling the HP48 programs. He gets a
few dollars for his work to put the programs together on a CD-ROM, not
for the programs!
Sure it would be good, if Eric could contact every programmer to ask
him, if he likes to see his programs on the CD-ROM. But imagine how
many E-Mails Eric would have to write (there are somethousand files on
and keep in mind that Eric doesn't get a profit from those CD-ROM, but
only some dollars for his really hard work. In addition those programs
were freely offered by many people (including you :-) to help other
HP48 users. Some years ago it was not possible to burn a CD-ROM, but
you could spread your programs via BBS. Today the world wide web and
CD-ROMS are some possibilitys to spread your programs. When Eric burns
a few CD-ROMS (everytime someone asks for the actual copy of the
web-site!) it's not more then fair to give him some dollars for the
time and material he spends on this. This is just another way to offer
those great HP48 programs to others for *free*.
When you download a file from hpcalc.org this isn't really free also.
I have to pay for my internet provider and for the phone. But this
doesn't mean that my phone company or the internet provider sells
those HP48 programs, when they enable me to download such files.
Excuse my minimal english. Just try to express my thaughts:
Laws are neccessary to protect the community and are good to have
therefore. I'm happy that most of us live in countries where we have
laws which gave us the personal freedom we enjoy to have.
Laws are there to prevent *bad* things. But here Eric's aim isn't bad.
Maybe a law would be against Eric's CD-ROM, but the aim of the law
wasn't to prevent such CD-ROMS, but to prevent someone to make money
of others work.
In german I would say: Nicht der Buchstabe des Gesetzes ist wichtig,
sondern die Absicht sollte entscheidend sein!
 Here the time Eric is spending on all his work (including the site,
which is collecting all the programs for the benefit of all interested
HP48 users, which enables him to burn such a CD-ROM) doesn't get paid
by the few dollars of some CD-ROMS!
But more important: Eric's aim is to help other HP48 users!
Must there be a law for everything :-)
That wouldn't be nice...

Good. LAWS !  Why didn't I think of it. Don't tell me you can't
make the difference between the spirit of the law and its actual
written content. And, something you may not have considered is
that not everything that has been legislated is good or smart :
What do you think of a law in Iowa that states that kisses may last
up to but no longer than five minutes ?
Or a law in Nebraska that actually insists that parents are to be
arrested if their child cannot hold back a burp during a church
service ?
In Texas you cannot go barefoot without a five dollar permit;
All bloody stupid things to legislate, wouldn't you think ?
And yet the number of examples of this kind is utterly flabbergasting,
as a quick research will show you.
Now, back to your case: You are complaining about somebody who
you feel is ripping you off some 10^-4 cents worth of disk-space ?
He's not cutting down the revenue of millions of people, is he ?
Add a couple of powers of ten if you care to.
Do you know that dozens of companies make money out of selling your
time and energy, that's a better case for you to concentrate upon,
no ?
You have no idea how many laws we all break daily :-)
 
Do you watch traffic lights at night when all is quiet...
...and send a weekly report to your nearest Police Department ?
Surely not. Get a life, Dan...

I've just been given a SX, so of course, the first thing I did was to
dump the rom for use with x48.  So far so good, but alas all is not
well.
Running checkrom on the rom file produces:
        ROM CRC reads 0x9602
        IROM OK: ROM CRC test passed.
which seems to me to indicate that the file has indeed been dumped and
converted correctly.
So what am I doing wrong?  Does x48 still accept SX ROM files?
Any help greatly appreciated.

Sorry about the long address. The .zip file contains binary versions of the

having
====
There is no problem on Emu48 with *binary* HP48 program files
(and libraries, etc.), because Emu48's Load/Store Object functions
are inherently made to work in binary mode, just as if you
were to use XModem all the time to transfer files,
no matter whether they were supposed to be binary or ascii
On a real HP48, when you use *Kermit* to transfer *ascii* program files
into or out of the calculator, the HP48 performs all of the essential
functions to translate non-ascii characters and compile (or decompile)
the program for you from (or to) its text format; however, Emu48's
Load/Store Object functions act only like the real HP48's *binary* file
transfer functions, hence ascii program files are not processed for you.
The following post contains programs that use the internal Kermit
ROM functions within the HP48 to receive and send any ascii text
from and to a computer file, so that Emu48 can behave exactly
like an actual HP48 in receiving and sending ascii program files:
These programs actually just transform text on the stack into
a program, or vice-versa; you can then use the Load/Store Object
functions of Emu48 to complete the transfer from/to a computer file.

After I knew that Bernard Parisse had released a new version of Erable 
(3.2),
I wanted to compare again the speed of HP's best tool I knew with TI's best
tool I knew for LaPlace, to find out how the new Erable changed (or not) 
the
results I had achieved. And I found that with the new Erable 3.2, HP is
faster and TI for LaPlace transforms. Let's see...
¡¡¡HP's 
corner¡¡¡
HP48GX's boxer for LaPlace transforms is the latest version of the superb
program by Bernard Parisse, Erable 3.2. We made a small program that 
performs
Erable 3.2 takes 84KB of memory and is much faster than the previous 
version,
3.1, which we used yesterday to compare speeds. So, we have decided to 
compare
TI and HP again today, for ver 3.2 does changes the rules of the game.
¡¡¡TI's 
corner¡¡¡
TI-89's boxer for LaPlace transforms is the First LaPlace proposal by 
Perez-
the
fastest and smallest formula you can type in TI to obtain LaPlace 
transforms.
It is described as:
     -¤(e^(-s*t)*z,t)|t=0
It uses 20 bytes of memory. It can be defined as a userd defined function. 
If
you know of any other tool for TI that solves LaPlace *faster* than this 
ultra
fast instruction, let me know.
¡¡¡How was time 
measured?¡¡¡ Since TI 
does 
not have an inner clock as HP
does, times were measured in different ways. In HP, the program we made 
gave
us the time. In TI, we used a Casio stop-watch and our eye. :o) We decided 
to
use huge functions in the transformations, in order to get big times which
can be compared without taking care my eye-hand's reaction time. Anyway, 
time
was rounded to just one decimal after the point.
¡¡¡How was this 
comparation made?¡¡¡ 1) 
HP 
thing was made in a HP48GX R
runing Java (this is necessary for pretty print, because TI gives answer in
pretty print and conditions must be equal for both), with Erable installed 
in
Port:1: and nothing else in user memory but a CST and the small program we
mentioned (125KB free) and new batteries. 2) TI thing was made in a TI89 
with
nothing else in user memory but the lap() user defined function and new
batteries.
¡¡¡Results[DownExclamati
on][DownExclamation][DownExclamation]
Function: 1 + t + 2*t^2 + 3*t^3 + 4*t^4 + 5*t^5 + 6*t^6
HP: 8.9 sec
TI: 10.6 sec
Rate: 0.84 (HP wins!)
Both gived identical answer display than MapleV.
Function: 1 + t*sin(t) + 2*t^2*sin(2*t) + 3*t^3*sin(3*t)

TI: 79.1 sec
Rate: 0.94 (HP wins!)
Both gived different answer display than MapleV.
[DownExclamation][DownExclamation][DownExclamation]Conclussion[DownExcla
mation][DownExclamation][DownExclamation]
Although Erable 3.1 is much slower than my TI's formula, the new Erable 3.2 

is
clearly faster than both.
If you have $300 to spend and know how to install in your calculator the
Erable 3.2 library of the genial Bernard Parisse, then the best hand held
tool you'll find to solve LaPlace transforms is HP48GX with 128KB RAMCard 
and
Erable 3.2 and Java (for pretty print) in port 1. This will allow you to 
make
LaPlace and InvLaPlace in the fastest way a human hand held device have 
ever
known. It is the best choice, but the most expensive.
For half the money, you can get a TI-89 and type in the entry line my 
LaPlace
proposal (-[Currency](e^(-s*t)*z,t)|t=0) and solve LaPlace transforms in 
the second
fastest way a human hand held device have ever known. No need for RAMCards. 

No
need for additional software. It is still a very good choice and it is 
worth
every cent of the price.

Help!
I used to have the HP file transfer program that came with the cable
for my 48gx. It worked fine but I can't find the disk anymore.  I for
the life of me can't get hyperterm or hp explorer to work!  I've had the
hp for 6 years and don't remember server mode ever working.  I've
followed the verbatim instructions on hyperterm that somebody had on a
web site dedicated to to downloading ROMs.  Duh... why can't I get this
to work?  I think I have the M rom.
Any assistance would be greatly appreciated.

LaPlace: HP's Erable 3.2 beats by far the best TI method I know
After I knew that Bernard Parisse had released a new version of Erable 
(3.2),
I wanted to compare again the speed of HP's best tool I knew with TI's best
tool I knew for LaPlace, to find out how the new Erable changed (or not) 
the
results I had achieved. And I found that with the new Erable 3.2, HP is
faster and TI for LaPlace transforms. Let's see...
[DownExclamation][DownExclamation][DownExclamation]HP's 
corner[DownExclamation][DownExclamation][DownExclamation]
HP48GX's boxer for LaPlace transforms is the latest version of the superb
program by Bernard Parisse, Erable 3.2. We made a small program that 
performs
Erable 3.2 takes 84KB of memory and is much faster than the previous 
version,
3.1, which we used yesterday to compare speeds. So, we have decided to 
compare
TI and HP again today, for ver 3.2 does changes the rules of the game.
[DownExclamation][DownExclamation][DownExclamation]TI's 
corner[DownExclamation][DownExclamation][DownExclamation]
TI-89's boxer for LaPlace transforms is the First LaPlace proposal by 
Perez-
the
fastest and smallest formula you can type in TI to obtain LaPlace 
transforms.
It is described as:
     -[Currency](e^(-s*t)*z,t)|t=0
It uses 20 bytes of memory. It can be defined as a userd defined function. 
If
you know of any other tool for TI that solves LaPlace *faster* than this 
ultra
fast instruction, let me know.
[DownExclamation][DownExclamation][DownExclamation]How was time 
measured?[DownExclamation][DownExclamation][DownExclamation] Since TI does 
not have an inner clock as HP
does, times were measured in different ways. In HP, the program we made 
gave
us the time. In TI, we used a Casio stop-watch and our eye. :o) We decided 
to
use huge functions in the transformations, in order to get big times which
can be compared without taking care my eye-hand's reaction time. Anyway, 
time
was rounded to just one decimal after the point.
[DownExclamation][DownExclamation][DownExclamation]How was this 
comparation made?[DownExclamation][DownExclamation][DownExclamation] 1) HP 
thing was made in a HP48GX R
runing Java (this is necessary for pretty print, because TI gives answer in
pretty print and conditions must be equal for both), with Erable installed 
in
Port:1: and nothing else in user memory but a CST and the small program we
mentioned (125KB free) and new batteries. 2) TI thing was made in a TI89 
with
nothing else in user memory but the lap() user defined function and new
batteries.
[DownExclamation][DownExclamation][DownExclamation]Results[DownExclamati
on][DownExclamation][DownExclamation]
Function: 1 + t + 2*t^2 + 3*t^3 + 4*t^4 + 5*t^5 + 6*t^6
HP: 8.9 sec
TI: 10.6 sec
Rate: 0.84 (HP wins!)
Both gived identical answer display than MapleV.
Function: 1 + t*sin(t) + 2*t^2*sin(2*t) + 3*t^3*sin(3*t)
HP: 10.5 sec !!!
TI: 137.3 sec

Both gived different answer display than MapleV.
Function: exp(5*t-3)+4*t^2*sin(7*t-Pi/3)+2*t^3/5
HP: 74.6 sec
TI: 79.1 sec
Rate: 0.94 (HP wins!)
Both gived different answer display than MapleV.
[DownExclamation][DownExclamation][DownExclamation]Conclussion[DownExcla
mation][DownExclamation][DownExclamation]
Although Erable 3.1 is much slower than my TI's formula, the new Erable 3.2 

is
clearly faster than both.
If you have $300 to spend and know how to install in your calculator the
Erable 3.2 library of the genial Bernard Parisse, then the best hand held
tool you'll find to solve LaPlace transforms is HP48GX with 128KB RAMCard 
and
Erable 3.2 and Java (for pretty print) in port 1. This will allow you to 
make
LaPlace and InvLaPlace in the fastest way a human hand held device have 
ever
known. It is the best choice, but the most expensive.
For half the money, you can get a TI-89 and type in the entry line my 
LaPlace
proposal (-[Currency](e^(-s*t)*z,t)|t=0) and solve LaPlace transforms in 
the second
fastest way a human hand held device have ever known. No need for RAMCards. 

No
need for additional software. It is still a very good choice and it is 
worth
every cent of the price.

I could not find anyone to repair mine, so I bought one from my

Place the grommel on a screw and chuck in a variable speed drill, and
use a dremel tool with a sanding drum.  Hold the sanding drum at a
right angle to the grommet.  It also helps if the dremel tool is
secured so that you do not have to hold both drills at the same time.

  You can physically plug in a 256K or 512K card without hardware
  problems (1MB or larger will interfere with the display),
  but an HP engineer (not speaking for HP, of course)
  has informed us in the past that you can not rely on which
  128K of the card will get mapped to Port 1 at any given moment;
  when I experimented myself with this at one time, I found
  that I did not get the first available 128K mapped at the time
  into Port 1, so I believed this advice.
  Since any sudden change in selecting which 128K bank is visible
  in the card could be harmful to the integrity of memory contents,
  he strongly advised against this practice, especially if
  you were thinking of merging memory.
  There are said to exist cards which have more than 128K, but whose
  bankswitching you manually control yourself; since slot 1 of the
  G-series cards is declared to be electronically identical to either
  slot of the S-series calcs for which said cards were designed,
  such unique types of cards might still work in the G-series (anyone
  who has such a card and a G-series calc might try it and tell us).
  In no case will you ever be able to access more than 1 bank (128K)
  at any one time of any card in slot 1.
  There are some fairly cheap 128K cards now available,
  sources of which are frequently discussed in this forum.
  Well, now you can be nearly 100% sure,

  On Goodies Disk #10, utils subdirectory, file pct555.doc,
  Joe Horn offers complete PCT documentation in English
  (which is quite a feat, since I didn't know he was so good
  at translating from the original French :)
If PCT is too big to fit in your cramped card full of libraries,
you can also use some non-graphical UserRPL Port Tools:
Additional UserRPL tools for moving directories to ports,
and for automated archiving into ports:
-----------------------------------------------------------
----------------------------------------------------------------------
I'll assume that you are using a similar version of PCT as I do...
First, make sure you're in the PORT screen (huge PORT in the right
edge of the display).  If you're not, press the SWAP key until you
are in the PORT screen.  (Or press 0 to jump directly to port 0).
the destination port number.  You can change the destination port by
pressing shift (either one), then [.], then type the number, then press
ENTER. (If you want port 0, 1, or 2, you can use a shortcut: shift number).
The menu key at the other end of the display shows the current port, that
is, the source port.  Changing the source port is done the same way as
above, without the shift key.  You can single-step through the ports by
pressing the source-port menu key; back-step by pressing a shift key first.
To select/deselect multiple objects, press ENTER.
To select/deselect ALL the objects in a port, press shift-ENTER.
Thus you can move many (or all) of the objects from one port to another
in just a few keystrokes.
You can force PCT to begin automatically with whatever ports you prefer
by storing the port numbers into 'PCFG' in HOME.  For example, { 2 15 }
sets the default source port to 2, and the default destination port to
15.
Hope this helps!
====
There was an update of sorts to PCT called FPX which was done by this 
guy
named Paquot.  He released it as shareware that had to be registered for a
nominal fee, but since he no longer had time to support it, he released it
as freeware.  So you might check that out if you get a chance.  It's very
nice and despite some complaints, I haven't had any problems with it.

There is an explanation of how to access them and get info about them from

I was looking at the ml code for COMPEVAL and I noticed that there was a
GARBAGECOL in there somewhere.  I was wondering if it is completely
necessary since a GARBAGECOL takes a lot of time (relatively speaking).
Since I'm not very well versed in Saturn assembly, I was wondering if
anyone could take a look at the code for COMPEVAL and a) explain to me
generally how it works and b) tell me if there is any room for
improvement.  The reason I have such a strange request is because I was
====
  What I see is that COMPEVAL pops the data stack (performing
  D=D+1 in the process) and then continues with the DOCOL prolog
  (used for program objects, which themselves are composites);
  DOCOL in turn does D=D-1 and then looks for a carry (meaning
  that there is no room to push a return stack pointer),
  which is the only condition under which GC would occur.
  However, since we just did D=D+1 within COMPEVAL, it is impossible
  for any GC to be triggered at this point by COMPEVAL; what is
  actually happening is that COMPEVAL is transferring one object
  from the data stack to the return stack, which neither increases
  nor decreases the room between the two stacks (D register).
  If COMPEVAL (or DOCOL) were actually to do a GC every time
  they were called, the poor HP48 would be dead in the water,

----------------------------------------------------------------------
I doubt it's possible.  The 32SII wasn't exactly designed to be expandable.
It has a few K of RAM, some parts of which you can't even get to directly
(they're controlled by the Solver, etc.).  The rest you can only get to in
very well-defined ways (Isn't the number of variables you can have limited
to 27?) What exactly do you expect to gain?
If you were going to upgrade the memory, you would probably need to rewrite
the firmware as well.
I could be wrong... I'd be happy to have one of the HP people correct me! 
But this is my educated guess.

grobs I display seem to flicker a little. I schedule a interrupt 1/64 
seconds
in the future and I rotate a grob table of three pointers where two point 
to
a lower half and one to the top half of a four shade grob. How do I make 
sure
I am synchronized with the VBL? Also, how can I produce delays when I am
using TIMER2 already. Do I have to use countdown loops that run different
lengths on SX/GX?
/Daniel
http://www.dejanews.com/       Search, Read, Discuss, or Start Your Own    
----------------------------------------------------------------------
Well, it has been a while since I played with greyscales...
You should likely schedule the interrupt a tick or two short of
the 127 ticks (128 counting the current tick).  Just subtract one
at a time until the flicker is reduced to a minimum.  And then in
the interrupt routine check the display line refresh and wait
until it is time for the new display screen.  Also, you likely
don't want to disable interrupts as this could also cause flicker.
As far as using TIMER2 outside of the interrupt routine...
I would ONLY change TIMER2 inside the interrupt routine, and also
include a counter also only updated only inside the interrupt
routine.  (Everytime you reset TIMER2, increment the counter.)
Then you can read TIMER2 and the counter to calculate the actual
number of ticks passed.
If you are using TIMER2 for your countdown, then it should be
the same on both SX and GX, otherwise it is a pain!
So, inside the interrupt routine...
1) Read the display line refresh until it rolls over (this should
   keep things in sync).
2) Reset TIMER2 for the next interrupt (127 ticks SHOULD work,
   but also try 126).
3) Increment an interrupt counter variable (lets name it IntCount).
4) Set the new display grob.
Outside the interrupt routine...
1) Avoid disabling interrupts!  (This will surely cause flickering
   and timer problems!  For example, you would likely miss the
   display refresh rollover, and you would need to use the negative
   TIMER2 count to calculate the proper count in the IntCount
   variable.)
2) Don't change TIMER2!  Just use the current TIMER2 value along
   with the current IntCount value to calculate the current tick
   count.  (IntCount*128-TIMER2)
   Or you can increment IntCount by 128 every interrupt.
   (IntCount-TIMER2)
   If you use a full 16 nibble value IntCount rollover should
   NOT be a problem.  Not for a few years anyway.  ;)
3) Depending on what you are doing, you may need to watch for
   TIMER2 rollover before performing some operations.  Just
   read TIMER2 and if it's value is too low (almost time for
   and interrupt) then wait.
This should give you low flicker and an accurate tick count
(using IntCount and TIMER2) outside the interrupt routine.
And there are variations on this...
For example, if you just need to know how long to wait until
you can change the grobs again...
For example, if you three grob pointers that are rotated each
interrupt, and you only want to change every rotation...
Then you don't even need to check TIMER2.  Just check the
IntCount value and wait until it increase by three over the
last time the grob(s) changed!  And you only need to save
a 1 or 2 nibble value for comparisons!
And if this is ALL you need, IntCount only needs to be 1

seriously.

It could also be that you are referring to using the stack? Everyone knows 
the
stack slows to a crawl when dealing with advanced formulas, swapping and
browsing the stack.
Solution: Get Java 3.7! Not only do you get pretty print, but it also 
speeds
up the stack so much, you'd think HP deliberatly slowed the stack down (why
would they do that?????)
Maybe also the Equationwriter? Try RainEQ 0.5! A bit unstable, but 
generally
it is ingeniously designed and supports editing of pretty printed formulas.
Something not even the all mighty TI-92 can do! RainEQ speed example:
Formula drawn in the Equationwriter: 60 secs. In RainEQ: 2 secs!
Or maybe the Matrixwriter?? Try Matrix V1.2 by Arnold Moy! Stable program,
which speeds up the Matrixwriter at least 10-15 times. Try changing the 
column
width with the Matrixwriter first and then with Matrix V1.2, and you'll see
what I mean!
Or maybe it's when cleaning up variables? Try PCTools5.6! It makes juggling
with variables, programs and objects a laugh instead of a pain. Most known
facilities from Windows Explorer in Windows 95 are very similar to this 
tool.
Or maybe it's when crunching numbers and formulas? Get ALG48 V4.2! Ho, Ho, 
Ho,
now we're talking! Forget the snailing EXPAND and COLCT commands. Use RSIM 
and
many other functions. They work much more reasonably and much faster.
Or maybe it's something totally different?? Get a memory card! Because all 
of
the above mentioned tools won't fit together in a HP48GX! Damn...

I have spent too long in the world of DOS and Windows, I suppose, because I
find myself wondering if there are any virusses for the HP 48. I am still
new to the machine even to know if they are possible, though I supoose a
virus could be written (or accidentally created) for any machine at all...

In brief, there ARE viruses, but they don't seem to ever have
been attached to anything online or on the Goodies Disks.
Fear not.

Since the HP 48G series is basically a (relatively) special purpose
computer, viri are definately possible. I haven't run into any myself,
but like you I am a new 48GX owner. If you are worried about viri, and I
have no idea how well founded those worries would be, you can get a
====
Most virus-resembling HP48 phenomena (crashes, memory wipe-outs,
disappearing data, etc.) are the result of mistakes in programs
written at the system or machine language level, rather than
of anyone trying to do harm; however, the end result of such
accidents, much like other kinds of accidents, is still
slightly unpleasant; thus it is a common recommendation
for anyone who needs to rely on stored information
in the HP48 and who uses any uncertain SysRPL/ML programs
and libraries to prudently back up memory on a PC.
If you don't have a cable and the experience to do this,
then probably you also can't manage to download any of the
programs which ever cause such problems, so the very fact
of being cable challenged is highly protective in itself.
In the winter, when electrostatic discharge phenomena increase,
it may also be prudent to avoid unprotected data exchange over
unshielded cables, at least until you make sure that you have

The FAQ has this to say on that subject:
http://www.engr.uvic.ca/~aschoorl/faq/48faq-4.html#ss4.16
However, I disagree with the FAQ.  The method shown there can
result in typed commands failing to work.  Here's a better
program which sets everything correctly:
BYTES: #553Fh 41.0
Works on all ROM versions (A-R).
INPUT: none.
OUTPUT: none. PATH is changed to the system's hidden directory.
PATH returns { HOME '' } with the null name invisible until
Do not re-order the final three items in the hidden directory.
Press HOME to exit the hidden directory.
The program above is the User RPL version of the CDHD command in
Mika Heiskanen's HACK library.
Hope this helps!

So feel free to NOT read!  ;)
Wow, I am somewhat taken back with the number of people who are
actually willing to show some sort of support for someone that
is selling something that is NOT HIS TO SELL!
[I have included some of the posts later in this post...]
Personally I HOPE that they just don't understand it.
Because showing support for someone selling items that belong
to other people WITHOUT THEIR PERMISSION is VERY LAME!
Selling something that belongs to others WITHOUT PERMISSION
show an extreem lack of respect both for other people and for
other people's property!
And showing support of such is NOT ANY BETTER!
Then again, maybe I am just a bitter old man...  :/
Still, in the hope of maybe opening a few eyes, I will try
to explain...
First, copyright laws are not just some old backwater laws
leftover from times past.  Most are fairly new, and many have
been rewritten for the computer age.  Also, they are fairly
commonplace throughout the world!
With all this support, it would seem that these must be pretty
good laws to have.
Basicly, a copyright is a way to give ownership to something
written down and that can be copied.  And a person does NOT
have to put a notice in writing to have a copyright (not here
in the US anyway)!  Unless the author explicitly puts something
in the public domain, or gives it away, or sells it, he has a
copyright!
This means when a program is put on a web site, or even when you
load someone else's program in your HP48, ownership STILL belongs
to the author!  You are basicly using someone else's program!
This is usually not a bad thing as MOST HP48 programs (except some
commercial programs and such) are meant to be shared!
But most of these programs are also intended to be FREE!
And as they belong to the authors, they should NOT be sold
without direct permission from the authors (the programs STILL
belong to the authors!).
Selling something that belongs to someone else is very lame!
It is WRONG, IMMORAL, and ILLEGAL!  And it is disrespectful
to other people, their property, and their rights!
And showing support for such an action is also pretty lame.
How many programs of yours is he selling?
If the answer is none, then maybe you should SHUT THE HELL UP!
Because while you have ALL the right in the world to speak about
YOUR work, you have NO RIGHT to tell me how to feel, or what to
do about MY programs!
[Hey, I went back and added the above just for you!  ;)]
Heh, clearly someone who is fairly NEW to comp.sys.hp48.
Please don't try and tell me how to feel or what I should do
about MY programs!
Actually, I can get GOOD legal service (more than one attorney)
that won't cost me a dime!
But then again, I don't really want to take some high school kid
to court just for being dumb!  And I HOPE it would not come to
that.
Oh please!
And how is this a bigger sin than turning a blind eye for something
that I KNOW is wrong?
Okay, finally a somewhat reasonable comment...
1) Joe Horn had my permission for everything of mine he included
   on the goodies disk.  In fact, I think I sent most of it to
   him just for that purpose!
2) To my knowledge, Joe did NOT RECEIVE ANY MONEY for those disks!
3) EduCALC providing those disks was strictly NON-PROFIT!  Any
   money they received was for the media and copying services and
   such!  They made NO MONEY from them!  And the programs and such
   were actually free!
4) While I supported Joe Horn and EduCALC with their goodies disk,
   I would be MUCH LESS likely to support a private individual as
   VERY few (if any) would be willing to go through the hassles
   for strictly NO PROFIT!
Now, IF these CDROMs were being sold for a non-profit price
(less than $5), then we WOULDN'T be having this discussion!
But selling something for profit that belongs to someone else
without permission, and often even without the authors KNOWING
ABOUT IT, just rubs me the wrong way!  But then, I guess I've
made that clear.
[Clearly someone who has little respect for laws...]
But then again, maybe I DID actually consider if it was GOOD or
SMART!  Maybe I DID actually consider that these laws are fairly
recent.  Maybe I DID actually consider that many of these laws
have been rewritten for the computer age (even IF some don't go
quite far enough!)!  Maybe I DID actually consider that many
of these laws exist in MOST OF THE WORLD!!!
Oh please!  Give me a break!
First, I don't live in these areas and have no idea how old these
laws are or such!  So I really cannot comment on them!
But they CLEARLY don't compare to copyright laws, many of which
are supported GLOBALLY!
First, I am NOT interested in ANY MONEY for my programs!  I fully
intended for them to be FREE!
But it REALLY pisses me off that someone feels they have the right
to make money off MY programs WITHOUT MY PERMISSION!  And I have
the RIGHT to be upset!  They ARE my programs!  And I also have the
RIGHT to let others know about it!
How others feel about it is totally up to them!  What others do
about it is totally up to them!
Feel free to comment about any programs of yours, but you have
NO RIGHT to tell me how to feel about mine!
(Oh wait! you did not even say you had any such programs!)
I hope you are speaking for yourself!  Because you are NOT
speaking for me!
I don't go out and intentionally break laws!
IF this CDROM is being sold because the guy did not know any
better, then he should quit selling it!  And he should give
a public statement saying so!  And he should give a public
apology for doing so in the first place!
(This I would be happy to accept.  But NOT anything LESS!)
Only when waiting to cross the street!  ;)
Otherwise, no, but then again I don't pretend not to see
when I am there and something DOES happen!
Again, please feel free to speak about your own programs!
But DON'T try and tell me how to feel or how to handle mine!
As far as getting a life?  I am thinking about thinking about it!
Okay, I'll make other respones below.
But I want to try and make this simple...
(Okay, okay, it is too late for that..., still...)
YOU have YOUR opinion and YOU think it IS OKAY if he sells YOUR
programs...
Do YOU have a right to this opinion about YOUR programs?
Of course YOU do!  They are YOUR programs!
Do YOU have a right to say he CAN sell them?
Of course YOU do!  They are YOUR programs!
I have MY opinion and I think it IS NOT OKAY if he sells MY
programs...
Do I have a right to this opinion about MY programs?
Of course I do!  They are MY programs!
Do I have a right to say he CANNOT sell them?
Of course I do!  They are MY programs!
YOU have the right to say YES, and I have the right to say NO!
But, he did NOT ASK me!  I had NO IDEA he was selling them until
after he had already started selling them!
This is WHY we have copyright laws!
This is WHY he is REQUIRED BY LAW to get permissions BEFORE he
sells someone else's programs!
But he did NOT get this permission from everybody!  He did NOT
even ask many of us!  And as such he did NOT give us our DUE
rights!  And this is VERY VERY WRONG!
Is is worth the effort to contact everybody whose programs he
wants to sell?  Likley not!
But it IS what he MUST DO if he wants to sell them!!!
He has a legal responsability to do so!
And he has a moral responsability to do so!
And otherwise he just should NOT SELL THEM!!!
If he was selling the CD for LESS than $5, then I would likely
agree.  And we would surely not be having this discussion!
it!  If someone wants to put them on an web site as a hobby, also
not expecting any money, then I see nothing wrong with that.
But when someone thinks they have the right to make money for
their hobby of putting my FREE programs on their web site, they
are wrong!  And more so when they don't even ask me or tell me
about it!
I donated my time writing the programs.  He is free to donate
his in putting them on a web site for the public.  But it seems
he thinks he has the right to try and sell CDs to not only get
the money for making the CD, but also for running the web site!
Sorry!  But this is just plain WRONG!
Sorry I cannot agree with you.
If he wants to SELL something that does NOT belong to him, then
he SHOULD contact those that it belongs to and get permission!
Otherwise he just should not sell it!  And there ARE copyright
laws in most of the world to support just this!!!
I did NOT donate my time writing FREE programs to create a job
for someone else!  And when a person starts getting money for his
TIME, it becomes a JOB, which is clearly for profit!
If he needs money to help pay for his web site (NOT including
money for his time!), he should ask for donations!  If he needs
money for his TIME he should get a REAL job!
You are free, and more than welcome, to your opinions about
programs.  And I don't mean to knock it.
But then again, there ARE laws that require the PERMISSION of
the owners before some sells their stuff!  And many don't even
know that their stuff is being sold!
Exactly!  And this IS EXACTLY WHAT HE IS DOING!
Again, I MUST disagree!
He is MORE than free to DONATE his time and work for putting such
a collections together!  But if he needs money for his TIME and
WORK he should get a REAL job!
Huh?
When he IS asking to get PAID for it?
Then one must question what are his REAL motives?
To help other HP48 users?  Or to MAKE money?
I won't say that he's not trying to help other HP48 users...

What do you mean what do I know!!! I am working for a large company (and
graduated from the same university you are attending). I fully
understand copywrite laws and beyond. A lot of the work that we are
working on has written information that our company has full rights to.
But I don't find myself roaming around making sure every Dick, Jane, and
Doe is adhering to the law. All I am saying is that if you are welcome
to police your own programs. It is your right and duty under the laws.
However, you don't have the rights or the duty to be telling others how
they should adhere to copywrite laws. Maybe you better take the Business
Ethics course and the Introduction to Ethics course. You will see that
there are too many sides to ethics flinging and find that a lot of the
information that you are flinging at others is ethically indignant.
Please don't feel that I am attacking you because that is farthest from
my mind. I respect you for the school you are attending and for your
ability to speak your mind and support your cause (not a lot of people
will put their foot forward, but flow with the crowd instead). If you
feel that you have been wronged, have a lawyer write up a letter letting
Eric know that he is in the wrong and have your programs removed from
the disk he is selling. Personally (please don't jump on my back), I
feel that the price isn't bad for the time, electricity, and supplies
needed to create the disk. Less than $5 would be a good price if Eric
had a professional facility with multiple ROM burners to mass produce
the disks, but if I am not mistaken this is all being done on his
personal machine (please correct me if I am wrong Eric). 
Again, if you feel that Eric is wrong, don't feel that it is necessary
====
Hmm. Yes I do cross the street when the lights are red, sometimes...
I feel there is a strong difference between a law and its purpose,
and I also feel that minor infringements which bear no negative
consequences for others can simply overlooked, because they are not
worth the effort and energy to be dealt with. It's against the law
to throw a cigarette on the road. Would you care to have everybody
who does so arrested ? Of course not.
as you think ( I have a different interpretation, but you may be
right in theory ), the damage is so irrelevant that it should not
take so much of our time to care about.
I didn't feel this would make me a better person in your eyes
to mention it. A quick search on my page (or Eric's site) will
tell you more if you care to. This seems to be besides the
point you are trying to make, though.
Sure you do, when your interpretation of the law differs from its
letter but not from its intention. Well, I hope you do...
I don't. Has Eric refused to withdraw them from his site/CD -
if you asked, that is ?  That would be a cause for anger, but
otherwise I see no problem worth to mention...
I hope my tone and my opinions do not irritate you, as it is
not my intention (not this time :-)

OK, I'll give you some support.  I agree, in part.
First the disagree part:
- The free software community is very well established and has legal
  documents detailing the copyright arrangements.
- The GNU copyright agreement (for example) contains the following
  paragraph:
  1. You may copy and distribute verbatim copies of the Program's
  source code as you receive it, in any medium, provided that you
  conspicuously and appropriately publish on each copy an appropriate
  copyright notice and disclaimer of warranty; keep intact all the
  notices that refer to this License and to the absence of any
  warranty; and give any other recipients of the Program a copy of
  this License along with the Program.
  You may charge a fee for the physical act of transferring a copy,
  and you may at your option offer warranty protection in exchange for
  a fee.
- While you apparently have a different idea of the copyright implied
  on your work, the simple act of freely placing it up for ftp implies
  TO MANY INTERNET USERS a GNU-style free software copyright license.
  Whether legal or not, if YOUR programs are the only ones with a
  different copyright (i.e. free for internet download, but NOT to be
  included on any physical media for which a fee is charged), you
  should make this known with a short explicit notice.
- It is very common practice for companies to create CDs of free
  software and sell them for a small profit.  Again, they are charging
  for the media, time, and overhead involved in creating the CD, not
  for the programs themselves.  This is allowed by the copyright.
Yes, I know, you did not place your programs under the GNU copyright.
But net users are used to thinking in those terms, and in fact many HP
users who release programs probably INTEND similar terms to be
followed.  My point is, be a little understanding of this culture.
You are certainly free to release your own software however you wish;
but I urge you to indicate this explicitly and not assume that
everyone else shares the same idea of which copyrights are implied.
You may have the legalities on your side, but I would ask that in the
interests of avoiding squabbles like this, helping HP users
everywhere, and general goodwill, you simply state what you intend.  I
also recommend this to others who INTEND a GNU-style copyright; if you
intend it, say it.
Now, you're probably asking where my agreement is.  This has all
been hypothetical so far, and I have not mentioned Eric Rechlin's web
site or CD.  $15 does seem a bit steep for CD's, but if you consider
the cost of a CD burner (part of the overhead) and assume relatively
few CD's sold, this could be in the ballpark.  I'll give him the
benefit of the doubt.  What concerns me are some of the terms in his
terms and conditions page, where it states:
  OWNERSHIP OF MATERIALS: Eric's HTML documents, identifiable by the
  Copyright Eric Rechlin text at the bottom, are copyrighted and are
  protected by worldwide copyright laws and treaty provisions. They
  may not be copied, reproduced, modified, published, uploaded,
  posted, transmitted, or distributed in any way, without Eric's prior
  written permission.
This does not grant the same rights that he is making free use of in
assembling the CD.  Since he does not give permission for others to
copy or distribute the same files, he is no longer charging a fee for
distribution, but is selling a product.  This is what keeps everyone
honest in other instances of distributing free software: It's all
free, so anyone can make copies and sell them for whatever they wish.
I could even copy most of the files off of some other company's disk
and make my own.  I would be much more comfortable if Eric made the
symbolic gesture of making his own pages free, in the spirit of the HP
community and free software in general.  He could certainly attach a
free for non-commercial use kind of copyright statement, and require
that no web mirrors be made in order to keep maintainance sane.  But
selling a CD which is an EXCLUSIVE copy of the web site, due to the
non-free HTML pages, really doesn't seem to be in the spirit of the
copyright agreement that I just defended at great length.
I hope this has helped clear up some of the hostile responses you've
been getting, and maybe even helped modulate your opinion on the
====
This is perfect. Legal information to support ones claim. This would be

                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
That is most reasonable :-). As far as I can tell, Eric does
not violate this (c)...

I was wondering if anyone knew where my HP48G could get a mathematics
package that performs a laplace transform on a LTI system?
----------------------------------------------------------------------
My old HP-41c broke down and I decided to buy a new calculator. A collegue
of mine came across some info on the TI-89 and I downloaded the manual to
have a look.
Based on positive experiences with my HP-41 I checked to see what HP has
to offer and came across the HP-48GX information. Unfortunately I was
unable to locate a manual that would allow me to compare it to the TI-89.
I'd like to be informed about differences between these two. The TI-89 is
based on the Motorola 68000 and probably allows me to use codewarrior for
development of applications, but what chipset is the HP based on?
What are the differences with respect to:
   - storage capability,
   - programming language,
   - available software,
   - interfacing to data acquisition hardware,
   - symbolic integration/differentiation
is welcome.

taking a college stats course.  The professor, in all
his wisdom, is choosing to teach the class dependent on
having a TI-82 or TI-83.  So far I have been able to do
everything on the HP, but now he is having us find the
standard deviation and the varience of grouped
frequency distributions.  If this makes sense to
anyone, is there a way to do this on the HP?  If you
response and I will try to fill in any gaps.

----------------------------------------------------------------------
I checked out the faq and found a program for weighted
standard deviations and means (5.17 I think).  I entered
it into my 48SX and press the enter key and promptly
received a syntax error message.  Turns out there is a
command toward the beginning of the program that tries
to do a col- to remove a column, and that command is not
allowed in programs or command line operations on the
48-S(X) per the manual.  I noticed later that this
program was for the 48-G(X)'s.  Is there another options
that will work with the SX?

----------------------------------------------------------------------
Yes, John H. Meyers posted some programs for this purpose, but I don't
know exactly how they are called. I think the programs are at
hpcalc.org (I don't know where exactly I've seen them)
or try a search on dejanews with the words SX GX  DOLIST DOSUB SEQ. I
think this will bring you to the right postings.
Good luck!

3 results when what we should get is { 19.02 18.08 }??????
JL
====
I think I know what is going on here.  When you eval the expression
'(1/50)*X^2-X+20', the HP48 evauluates '(1/50)*X^2' then subtracts the
evaluated expression 'X', then adds 20 to the result.
'(1/50)*X^2' evaluates to { 0.02 0.04 }
'X'          evaluates to { 1 2 }
If you subtract { 1 2 } from { 0.02 0.04 }, you get { -0.98 -1.92 }
Now, if you add 20 to { -0.98 -1.92 }, you get { -0.98 -1.92 20 }.
Why?  Because the default behavior of the '+' command is to append 
lists.  the ADD command is used to add corresponding list elements.
This is to keep behavior consistent with the HP48S/SX.

so that to get the correct results, you'd type 
'(1/50)*X^2-X ADD 20'
Ack!
that looks VERY conterintuitive though...!!!
i would think that in a case like this, the more 'reasonable' solution would 

be
to 'be aware' that you're going to have this problem and instead use DOLIST 

to
perform the operation on the List...
hmmmmmm...
it turns out, that you can't use DOLIST.
or if you can, how...???
What is the intuitively correct solution for this problem...???
no wait...
ok, i got it...

Greetings, JO[CapitalIGrave]O MIGUEL CORREIA DA CUNHA LOPES:
Automatic list processing works with built-in HP48
commands and functions, but not with UserRPL programs.
When a user program is evaluated, each individually
executed separate user command does whatever it does
independently; some of the commands in the user program
may do what you expect, while others may not.
In the case of the above, all works as you would like,
until you get to the + function within the expression;
at this point, the original meaning of + operating
upon a list is to concatenate new objects to the list,
rather than to perform numerical addition;
this is just what happens, appending the value 20 to the
list, rather than adding 20 to each element of the list.
So, don't kid your sister by over-generalizing
HP48 G-series automatic list processing :)
However, '(1/50)*X^2-X--20' should work
[subtracting -20, eliminating +]
In general, list processing may properly and generally
be extended to UserRPL programs (and algebraic formulas)
via the DOLIST command, e.g.
  'Y(X)=(1/50)*X^2-X+20' DEFINE
  { 1 2 } 'Y'  DOLIST
(in place of +) in algebraics; this does create a longer
====
====
This is why trying to be clever about backward
compatibility is a Bad Thing.  HP tried to make
the 48G backward compatible with the 48S - which
did not do list processing in this manner (it had
lists - which was why + meant catenate when
applied to them - but it could not automatically
iterate over lists - this was an APLish add-on
that occurred in the G).  The correct solution
was to set aflag for emulation mode - setting 
minus whatever would make + do catenation - and
+ would forever mean addition and cat (or 
whatever) would forever mean catenate.  They
actually did this with the hp41/hp42 - where the
42 would automatically switch to complex results
where necessary (i.e. sqrt(-1) worked as expected,
this extended the 41 set (which could handle com-
plex numbers only if you entered them, it did not
generate them from operation with non-complex num-
bers (it errored on sqrt(-1)).  So the 42s was
given a couple of flags to make it's behavior back-
ward compatible without  having to compromise the
newer way.  Sadly, the 48G didn't do this, and this
kind of unorthogonal behaviour is the net result.
I'd truly like to see this corrected in the new calc-
ulator when it comes.  But then, I'd truly like to
see the man who decided + sometimes _didn't_ mean
add get his butt kicked around the block, too.  And
not just the HP guy who did it to RPN, this is one of
the most common gotchas in programming.

It seems the HP48 first adds 20 to the first two results (using ADD), then 
does the
correct thing and
adds the argument (20) to the list, just like he does if you enter {1 2} and 

add 20

nice to see you again.
I see you've got your cable. Erable is an algebra and *general* math
program. It's some sort of Derive for the HP48. What do you want to
calculate with it?
Oh, not to forget: The *readme* or better the whole doc of Erable is
available in postscript and I think now also pdf format.
For the pdf format you need the free Acrobat Reader from adobe.com. To
print out the postscript file you can get the free ghostscript and
ghostview. (Don't know the address at the moment, but a search engine
will tell you quickly).
You still have a G, haven't you? Then unfortunally you can't install
Erable, because it needs about 90k free memory. If you like to do
specific tasks which Erable is capable of you may find a smaller
program for that specific task. Just tell us, what you like to solve.
Then we can give you some suggestions.
Weather's still bad in Cologne ;-)

Actually, I think there is a funny problem here; if you multiply the
solutions you give by the coefficients for x and Y, it looks like the
solutions are OK.  However, if you write it as matrix and use matrix
multiplication my HP gives
[[0.524][0.273]], which is not [[1][0]].
If I do this with Mathematica or SPlus I get the same solution (with
more digits).
The solution that Mathematica returns to the system of equations is:
x=885781
y=887112
If I check this solution in Mathematica or SPlus (or with the long
library that comes with ALG48 in the HP) is OK.  (However, if you use
the built-in multiplication of the HP it is not!).  The problem is in
the multiplication of those numbers; because if you multiply in the HP ,
e.g.,
888445*221359.125805 you get 196665408526, when in fact the result is
196665408525.823225 (this I get from Mathematica, SPlus, and using the
library long ).  Thus, by losing the decimals, when you check your
solutions they seem to be OK.
The result from the linear system is to be expected, because the matrix
is near-singular. But then, I found it perplexing that, in the HP if I
multiply your solutions term by term they are (incorrectly) apparently
OK, but when I check the solution with matrix multiplication, the HP
returns the correct numbers (0.524, 0.273).
Can anybody explain this (I guess I am missing something very obvious)??

how terribly we suffered back then without an expandable stack!).
But then I thought I remembered from the HP35 manual of the time (early
1970s) that the T register implied trig as a subtle warning to users -
the trigonometric functions needed temporary storage and they used stack
level 4. Anything the user had there was overwritten. With the HP45, the
trig scratchpad was moved to storage register nine, presumably on the
grounds that it would seldom be used by the owner (seems true - if I
used more than four STO registers I had to start writing them down).
The HP48 manual carries on the tradition - the commands that require
four stack levels still use x, y, z, and t to denote contents.

a friend gave me an url (
http://www.cris.com/~ramos/hp48/hp48xgcc.htm#what ) for downloading a
C-Compiler for the HP48.
I wanted to test it, but I have a problem. After transfering all
necessary files (gccldd and the libraries *.sl) and the compiled version
of one of the sample-programs to the HP, I wanted to link it. So I
started the compiled program. But the HP displayed the following error:
    Insufficient Memory
But I already have over 150 KB free.
Does anyone know something about this compiler and problem?
----------------------------------------------------------------------
    Furthermore, the explanation of IBP is not very clear to me.  The manual 

suggests to put an *integral* at level 2 whereas it has to be an 
*integrand*.  The third line seems to have a typo:  instead
    $f(x),dx=u(x)v(x),dx$
    
it should read
    $int f(x),dx=int u(x)v(x),dx$
    
or
    f(x)=u(x)v(x)
shouldn't it?  The fifth line is incorrect as well; one can read:
    texttt{1:} $-bigl(int 
v(x),dxbigr)cdotfrac{du(x)}{dx},dx$
                                                                ^^^^
but surely the last dx has to be ommitted.
    The example reads:
    2: 'ASIN(X)^2'
    1: 'T'
    
This yields on my calc:
    1: -0
    
Shave my legs and call me Grandpa!  Replacing T by X gives the result in the 

example.  How do I know that the function is completely integrated by IBP?  

    Let's face another example, namely x*sin(x), i.e., u(x) := x, v(x) := 
sin(x).
    
    2: 'X*SIN(X)'
    1: 'T'
yields the above, applying
    2: 'X*SIN(X)'
    1: 'X'
    
the result is:
    1: 'X*X*SIN(X)'
    2: '-X*(SIN(X)+X*COS(X))'
    
According to the manual I should get
    1: u(x)int v(x),dx = -x*cos(x)
    2: -(int v(x),dx)*u'(x) = -cos(x)*1
    
What am I doing wrong?  Nevertheless, Erable sure is a great program and I'm 

Anyhow, despite being a mathematician:
[x] I do not understand.  :-))

PS:  Providing the tables in appendix B with the page number where the full 

     explanation and description of the resp. function resides would greatly 

     improve the manual: this shouldn't be a too big deal using LaTeX. --

there's a more accurate alternative: CNRM.
SigmaLIST adds the numbers in a list by keeping a 12-digit
running total.  But CNRM adds the (absolute value of) the
numbers in an array by keeping a 15-digit running total, and
then rounding the final result to 12 digits.  Thus CNRM will
generate the correct answer whereas SigmaLIST can exhibit
round-off errors.
For example, 1/x added to itself x times (which is NOT always
equal to 1 on a finite-state machine) will get different
answers depending on whether it's done using SigmaLIST or
CNRM.  Here are some interesting comparisons:
     Calculation: 1/x added to itself x times.
               x: 11
SigmaLIST result: 0.999999999999
     CNRM result: 1.
  Correct result: 1.
Comment: Sometimes SigmaLIST is too low.
               x: 23
SigmaLIST result: 1.00000000001
     CNRM result: 1.
  Correct result: 1.
Comment: Sometimes SigmaLIST is too high.
               x: 26
SigmaLIST result: 1.00000000001
     CNRM result: 0.999999999999
  Correct result: 0.999999999999
Comment: Even when CNRM seems wrong, it's right.
               x: 92
SigmaLIST result: 0.999999999968
     CNRM result: 1.
  Correct result: 1.
Comment: SigmaLIST drifted off by 32 counts in the last place!
The correct answer was determined using Mika's LONGFLOAT
Unfortunately, CNRM adds the *absolute values* of the elements,
so it's not a useful replacement for SigmaLIST if there are
negatives in your data set.
Bottom line: if you use SigmaLIST to add up positive decimal
numbers in a list, replace it with the following for greater
accuracy:

This is a nearly philosophical question, yet to me there seems to 
be an obvious answer.
You are talking about _local_ variables.  They are local in the
sense that they are defined and usable in one part of the
program, and not in others.  So, in being local to one part of
the program, how does one know which part?  Well, it's the part
one know when that locality begins or ends?  What would a local
variable be without its locality?  (Global, I guess.)

That's right, but there's another reason: You are allowed to use almost any
names for your local variables, unlike globals. You need a mark (<<) to
of locals you wish to create), and when the program starts. Look at the
following (easy) example, and predict what is on the stack after it has

Okay, this is exactly the kind of exchange I was hoping for, constructive,
with good ideas.  I just thought I'd mention that the day after I posted 
the
original, I got a reply from someone (who shall remain nameless) asking
where to find information on the new HP58...  (I thought mythical and
wish list would make it abundantly clear . . .)
As for the QWERTY question?  I still find that the TI-92 is entirely to
unweildly to use effectively.  I would accept the clamshell design of the
28, maybe even with a sideways QWERTY, but that is most defenitly low on my
list, as I can type 30 wpm on my 48...  (Lots of practice)
And, I just saw a Gameboy color, and I have to say, if HP pulled color off
as well as on that machine, and kept long battery life (at least a month of
heavy use), I would accept color.  But again, that's low on my list.
Support, needed, badly.  HP used to (even unofficially) have great support
(when the calc division was still just down the road from me in Corvallis,
OR), and strong (again, even unofficial) support would be great.
Finally, the feel.  I agree, the TI's feel like toys.  I remember way 
back
in high school, doing a physics experiment, and I was (of course) the only
one with an HP, everyone else had the school-provided TI-81s, and one 
person
dropped a 500g weight on his, and it snapped the case like a small twig,
destroying his calc.  Just for fun, I started dropping the same mass weight
slightly
bend the faceplace where the 'hp' logo was (upper left of the SX)  So, I
have to say that the feel should not be changed for ANYTHING!  I may want 
my
watch titanium so it's light, but I want my calc to feel solid!

programming -

Just a little nit-picking of terminology: The kinds of programing
languages you aree talking about are actually called _low_ level
languages, because they are closer (lower) to the hardware.
As for what the next HP should have....I agree so far with what has been
said. Keep it about the same size, although a larger screen would be
nice, don't _make_ us use a QWERTY keyboard, etc. My personal opinion is
that if you want a QWERTY keyboard, buy a WinCE device and get the HP
emulator for it. I realize that this means that you still need to buy
the calc, but a lot of us would rather use a computer for the kind of
things that a QWRERTY keyboard would be used for.
The most important thing for me would be that they don't change the
_feel_ of the calc. I've owned several Casios and used TIs in the past,

Exactly what version of Pascal did _you_ use that
didn't have any data types?  Even the p4 compiler
had record types, son.
And don't confuse modern standards with ancient ones.
Neither Dartmouth nor Wirth have had a great deal of
influence on Basic or Pascal lately.  Basic's Kurtz
worked on the True Basic standard which is ANSI/ISO.
Pascal now has base and extended ANSI standards which
define all of the above features.
Wirth himself has produced a number of successors to
Pascal, including Modula/2 and Oberon-2 - the latter
would make a fairly ideal programming language for
a calculator as it is concise, object-oriented, and
modular.
Personally, I think RPL has real potential as a gen-
eric high-level language.  I'd like to see RPL take
a few pages from Smalltalk, leave behind a few features
that don't scale well, and see HP release an open-source
would be a formidable system.
C?  World's highest-level assembler?  The one that
insists on passing all structs as values and all
arrays as variables?  The one last language that
still has a global goto, except for C++?  The one
where int could be 16, 32 or 64 bits long depending
on what compiler you are using and what flags are set?
That C?
Java I can relate to, though I think syntactically
it's as big a mess as C.  foo==bar is not a very
obvious way to tell if both foo and bar refer to
the same object when foo.equals(bar) is required
to tell if the values to which foo and bar refer
to are the same.  Those are implementation details,
they shouldn't be shining through.
Tcl vars _are_ always initialized.  They are initialized
to  unless you set them to something else.  And Tcl
has no provision for defining new data types, nor does
Perl.  Python does, but Python also uses indenting to
define program blocks - not a fun feature on a tiny
display.

       My opinions only.       |
----------------------------------------------------------------------
I am refering to Nicholas Wirth's version of Pascal.  Not as the language
may have mutated to during the passing years.  Many of the `Pascal'
programmer learned the language on those early versions and still do their
variable initializations using assignment statements, for example.  That
is the nature of the poor programming styles to which I refered.
I did not confuse them.  You did.  Yopu seem to believe that Pascal
programmers have adjusted their programming style.  I do npt see
evidence of such progress.
The languages still encourage poor programming practices.
Yes, those are much improved languages.  That is why I did not offer as
examples of poor language models.  Since I am not comfortable with them
at all, I could not justify using them as examples of good language models.
Fortran 90, Cobol 85 and PL/1 also have ``global gotos;''
depending on your exact meaning---Fortran 90 and PL/1 do not
permit branching to compound statements.  Cobol does not
even have a solid idea of a procedure or compound statement.
That is not syntax, that is semantics.  And, there is a very good reason
for making the distinction ---
Using C as the example:
        int A = 1, B = 1;
        print(Same variables? %sn,(&A==&B) ? Yes : No);
        print(Equal variables? %sn,(A==B) ? Yes : No);
There is a strong need for being able to make both tests.  Java is OK.
If you are following a linked list, for example; then you might want
to test whether you have returned to the same object during your search.
Even the first edition of the K&R C language book deprecated the use
of the goto statement.  And, I have never found them to be necessary.
What I do miss (and which I had encountered in PL/1 is labeled loops
which permitted such (in a pseudo C like form):
                           for(j = x; j; j &= j-1) {
                                      if(i == j) break fred;
                           }
                 }
Initialized variables are A & B above, particularly if they are statically
allocated and already have their values when executions.  Tcl behaves like
the original Basic and Pascal languages, variables are initialized by
assigning values to them.
Notice that I said ``models.''  The language needs to be tailored to the
envionment in which it is used.
----------------------------------------------------------------------
I did.  You said, and I quote more exactly this time,
both are missing reasonable data types.  Pascal, even
Wirth's, had integers, reals, enumerations, strings and
records - at a time when C didn't have enumerations.
How much more reasonable do you need?
And spare me the testy responses.  If you didn't want
a discussion of the topic, why did you post?
Then you are referring to a language that hasn't seen
the light of day in two decades.
_I_ refer to the ANSI and ISO _standards_ for the Pascal
language, not some cockamamie proprietary extension.
Complaining about features missing in Pascal because
they were missing in Wirth's initial implementation is
like complaining that Fortran lacks complex number
support because you only used the IBM 1130 Fortran II
compiler.  If you aren't familiar with the standard,
fine, criticize ancient history if you like but don't
expect to be taken seriously.
Regardless of what your favorite feature might be, using
assignment statements to initialize a variable is _not_
among the bad programming habits people like Knuth or
Djikstra have enumerated.  Nor is variable initialization
a make-or-break feature of a language.  Wirth, at least,
continues to disagree with you, even Oberon does not have
initialization.  If you want to talk taste, fine, but
don't try to caste it as one of the eternal verities.
As for the utility of the feature, see below.
Basic, perhaps.  There is only one implementation that
respects the standard I am aware of, and the field is
loaded with non-standard mutants of immense popularity
like Visual Basic, which think of themselves as their
own standard.  Pascal, however, has done quite well by
comparison - but even in its original version, the P4
compiler encouraged good programming by the standards
of the time, and modern versions do as well or better
by the standards of today.
Yet you offered C and C++ as exemplars of good program-
ming practices - languages where even experts have
trouble writing portable programs.  You complain of
Pascal being unorthogonal yet C is a mass of special
cases, from inconsistant handling of null pointers
(which sometimes crash standard library procedures
and sometimes don't) to inconsistant handling of data
types (where structs can be treated as values in para-
meter-passing but arrays cannot).  And C++ is just
unspeakable, I suspect Stroustroup created it just to
make people realize how simple and elegant Ada was.
All of them ancient history and none offered as superior
to Pascal.
But Pascal having a goto is a Bad Thing and C having
one is okay?  That is the message you are sending.
Yes, there is.  But there shouldn't be.  It's an
implementation detail shining through the compiler.
In Java, yes, that need was built into it.  But it
is hardly necessary to make the distinction and few
other languages bother.  It's an artifact of trying
to adapt C-style coding practices to a language that
is trying to look like C but not support explicit
pointers.
So did Wirth's book about Pascal.
Nor have I.
Useful but still just syntactic sugar.
As I said, this is not a make-or-break feature of the
language, and they complicate implementation and linkage.
And I've dealt with far too many programs that managed
to clobber their initialized global space to have much
something else entirely under Windows, where even con-
stants may not be all that constant.  Initialized var-
iables are a valuable aid to documentation, but they
make little difference in the reliability of software,
and absolutely require memory management hardware to
be worth the expense of implementing them, IMHO.

        areas
                 which could be mapped to shared memory
        I wanted a dicussion of the topic.
        I did not want any testy responses, such as yours.
        Be careful of whom you can ``son''.
        You are not one of my parents.
        ANSI and ISO _standards_ are mutations of
        the original language.  According to you,
        those are not ``some cockamamie proprietary
        extension.''  They are an effort to correct
        the design errors of the original language.
        It is the design errors of the original
        language which are the source of my complaint.
        Those design errors caused many students to
        learn poor programming practices.  The newer
        variants of the language, to preserve the
        usability of the `dusty decks,' permit the
        use of the older constructs in the old way.
        The result is no pressure to learn better
        programming practices, even if one is using
        compilers which support the newer variants of
        a language.
        At least get the system correct.  Fortran was
        developed on the IBM 709 and 709x (x=0 or 4)
        series of IBM computers (mainframes of their
        day).  I have programmed in FORTRAN II on an
        IBM 7094-II, which is the first version of
        Fortran to be released officially by IBM and
        have done extensive programming in FORTRAN IV
        on an IBM 7044, which the lower performance and
        slightly difference variant of that architecture.
        Ancient history is exactly what I am addressing.
        The habits formed by those languages are hard to
        break.  The students which used those language to
        learn how to program are the teachers of today.
        The sins of that generation is being passed onto
        the current generation of students.  I would like
        languages designed to encourage strongly not to
        use those poor programming practices, which is
        where I feel this thread started.
        I do expect to be taken seriously.
        I have had problems with TeX because of its design
        which came in part because of its Pascal heritage,
        in particular because of Pascal's failure to have
        compile time initialization.  Tracking down uninitialized
        variables in TeX on a AT&T 3B1 was nightmarish.
        C is quite consistent.  People using it
        to implement `standard libraries' and
        other code were not careful using it.
        The result is the crashes that you
        mentioned.  The difference in handling
        structs and [] was and is quite clear
        in first and second edition K&R and
        in ANSI/ISO C.  It is just that many,
        such as you, find the specification to
        be surprising.
        This is far away from my original topic.
        It may be a topic close to your heart.
        You seem to want a language which is verbose,
        operator and data type poor, which is simple
        to program in because of those restricted and
        restrictive resources and obtain the results
        desired in comparatively simple programs
        (which is the purpose of student languages).
        I prefer languages which are terse, operator
        and data type rich even if this means that
        one must be careful when using the language.
        The HP48 user RPL is terse and operator and
        data type rich.  It also, as I remember,
        lacks a goto statement (I do not have my
        manuals at hand to check).
        You are incorrect.  I received my first
        C++ compiler by asking Bjarne Strousup,
        himself, for it.  I have had the pleasure
        of several conversations with him at
        Bell Laboratories and of hearing several
        presentations on the history and design
        of the C++ language.  These included
        dicussions of his purposes.
        Ada, to me, was an attempt to correct
        the design problems of Pascal.  It is
        interesting to note that the United States
        Department of Defense has dropped officially
        any requirements to implement systems in
        Ada.  Ada 95 seems to be the last Ada.
        All are superior by design and features to Pascal.
        Apparently, I ``shot your hobby horse'' (Pascal).
        They are all individually more heavily used in
        production code than Pascal.
        No, I only was pointing out that other languages
        also have the goto statement.
        The question is not whether a language has a goto
        statement.  The question is whether a language
        encourages a programmer to use the goto statement
        that a language may have.  Fortran until Fortran 90
        encouraged the use of the goto statement.  Cobol
        has a `feature' that is even worse than Fortran's
        assigned goto---the ability to modify where any
        paragraph proceeds to upon completion in a manner
        that leaves the fact of that modification quite
        invisible.  PL/1 shares with C and C++ the strong
        discouragement of using the goto statement that the
        languages have.
        Try 2.
        You do not seem to understand the need to
        have both the ability to determine whether
        two references to variables are to the same
        variable or to two different variables with
        the same value.  Some language attempt to
        define away the need and the problem by
        stating that programs which have such a
        need are incorrect programs because of that
        very need.
              INTEGER A /1/, B /1/
        C  The following is acceptable per the Fortran standards.
              CALL SUB(A,B)
        C  The following is `undefined' and `implementation dependent'
        C  per the Fortran 66, 77 and 90 standards.
              CALL SUB(A,A)
        SUB may need to test for and behave differently
        depending which of the two calls it receives.
        I do not disagree with you about it being ``syntactic sugar.''
        But, the reasonable, efficient, effective implementation of
        this useful, frequently occuring construct is a goto statement.
        The presence of such labeled loop and corresponding labeled
        breaks and continues eliminates one of the strongest pressures
        to use goto statements.  Once one starts using the goto statement
        to implement this construct, one is susceptable to using the
        goto statement elsewhere in even less appropriate uses.
        I suspect that many of the goto statements int the game
        in a different thread) are mostly implementations of
        these constructs.
        Yes, I have seen Fortran compilers which did not
        create temporary variables in the following situation:
                 ...
                 CALL SUBR(1)
                 ...
                 SUBROUTINE SUBR(A)
                 IMPLICIT NONE
                 INTEGER A
                 A = A+1
                 RETURN
                 END
        That is not a language design issue per se. The language
        specification should specify that only variables may be
        passed and that, if necessary, temporary variables be
        created or the language should provide for restricted,
        read-only access to arguments so that the compiler can
        generate the appropriate code for the case that the
        procedure does not change the argument and checks that
        the procedure in fact does not change the argument.  Of
        course, a clever programmer can always find a way to
        circumvent should checking.  The early FORTRAN language
        specifications did not make that requirement clear.

It wasn't a testy response, it was one that poked mild
fun at your own prejudices.
No language I've ever heard of supplies all of the above
types as primitives - and none needs to if it supplies
the means of building them, which both C and Pascal do.
To proclaim one language deficient relative to another
on the basis of built-in primitives is disingenuous to
say the least.
You unquestionably have the wierdest view of what
constitutes the definition of a language I have
ever heard of.
They undoubtedly addressed what the standards committee
felt were ambiguous or deficient features - so what?
They still define the official language.  When the
ANSI/ISO standard for Pascal was adopted, Wirth's
compiler became just another non-standard dialect of
limited historical interest.  It is silly to assert
that Wirth's version is somehow the Pascal and to
ignore the international standard version.
Then you are complaining about a complete
non-sequiter.  That dialect simply isn't to
be found in use any more, so why complain
about it?
Perhaps so.  But if they were any good as programmers
they learned better later, and if they weren't then
they wouldn't bother to learn new languages, either.
Again, I don't see any point to this assertion.
I did.  I learned Fortran II on the IBM 1130 at the State
University of Oswego in 1974.  It's the most primitive
version of the language with which I have personal know-
ledge.
Yet you offered C as a better choice than Pascal - a
language of the same generation, with the same faults,
plus a raftload more.  If your argument holds any
validity at all for Pascal it holds for more for C.
It's getting more difficult with every post.
I can tell similar horror stories about C.  So what?  TEX
is _old_.  Had it been targetted to the C of the time it
wouldn't even have had function templates, since that was
not a K&R feature - oh, we _are_ talking about K&R C here,
and not ANSI C, right?  They did, after all, do for C what
Wirth did for Pascal.
No, we find it to be inconsistant, and a major
violation of the principle of least surprise.
Arrays and structs are just two ways of aggr-
egating data.  That they should be assigned
such different semantic implementations is
silly - and makes sense only because of the
history of the language.  Ritchie implemented
arrays as variations of pointer arithmetic -
it was simple, cheap, and easy to implement.
Later, when structs were added to the language
(chasing Pascal at the time), this paradigm
broke - but C and now C++ continues to per-
petuate this design misfeature to this day.
Dusty deck syndrome was your word for it,
I think.
This isn't a simple quibble over perceptions.
Arrays in C are a low-level construct, as is
the address arithmetic - both, in fact, clearly
reflect the architecture of the PDP-11.  We
continue to perpetuate this despite the pain
of trying to compile to newer architectures.
The prefix/suffix ++ and -- operators were
invented soley to take advantage of the PDP-11
prefix and postfix indexing modes without
having to write an optimizer.  In terms of
clarity they had nothing over simply adding
1 to a variable with a normal assignment, and
they give modern optimizing compilers fits
because many language constructs now have to
map into the same output.
C is a dinosaur.  It shows its cobbled-together
history everywhere.  Now don't get me wrong, it
is a useful dinosaur, and any new calc will
need a C compiler to be popular - but don't
try to tell me that C is superior to Pascal
_because_ of these warts.
Hardly.  I want a language as easy to read as to
write, and I want one that uses a minimum of
syntax and concepts to get maximum utility.  As
for a plethora of data types, they can be useful
if they all or nearly all map to your problem
domain, they are useless code bloat if they
don't - and even if the linker can reduce the
bloat, the bloat in the documentation is just
as bad.  Worse, bloated languages compile slower,
and require much more complex compilers.  Oberon
can do anything C++ can do, it can do it faster,
and it can do with less code - even if it is
more verbose - and the compiler is less than
4000 lines.
Bugs scale with lines of code.  The Oberon com-
piler may well be bug-free, or nearly so.  C++
- _any_ compiler - has more bugs than a bait
store.  Entire newsgroups are dedicated to try-
ing to sort them out, more are dedicated to
fixing them.
Use J.  Or APL.  Or REBOL.  Heck, use C if you
like it.  I don't care.  Just don't hand me a
turd and tell me it's fudge.
You also have no sense of humor at all, I see.
C++ was a valiant effort, but has evolved into
Hell.
me, have you ever implemented a compiler?  For
any language?
Nope.  Never use it.  I do everything in C, personally
and professionally.  But then, I _am_ a professional,
and I can use power tools with bare wires and no covers
on the spikey spinning parts - tools that would disembowel
and shred inexperienced users.
However, that does not mean I enjoy it.  There are many
times when I'd like to be able to write a program without
having to worry about wiping out the stack, leaking
memory, or checking out-of-band results for sentinals
indicating major failures.  RPL is an excellent choice
for this - but so is Oberon.  Pascal could leak memory,
but it had fewer of these issues than C did (and does).
I'd frankly rather see HP concentrate on RPL, but if
they need another language they will need C - but be-
cause of the dusty deck syndrome, not because it is
better.  I'd rather see a Pascal-derivative, myself.
They are.

While you two continue your valuable and interesting oral history 
discourse
on the etymology and relative merits of programming languages over time, I
offer the following observations.
First, I can write reliable and nearly error-free programs in BASIC, 
FORTRAN,
Pascal, PL/1 and PL/I (do you know the difference?), C, C++, RPL, et 
cetera.
My software is reliable because I engineer it to be so. It is my techniques
and attention to detail, not the language, that determines this outcome. I
write structured code but have the wisdom to know when to break the 
rules.
I was using object-oriented design and implementation in C before I knew 
that
it had a name before I began paying attention to C++.
So: who cares what's in the language? I've seen perfectly good languages
wrecked by idiots who can't design or code their way out of a paper bag. I
would not (and probably could not bring myself to) use a language whose
design succeeds in compensating for their weaknesses. I had enough of a 
taste
of that with Pascal, thank you. (<-- flame bait ;-)
The fundamental characteristics of RPL that you would sacrifice in adopting
any of the above languages are simplicity and extensibility. RPL has it. 
LISP
and Scheme have it.  BASIC, FORTRAN, Pascal, PL/[1I], COBOL,  C, C++, and
Java don't have it. (I can't speak to Wirth's languages other than Pascal
because Wirth is worth ignoring past a certain point.) These are not just
niceties, folks, they are _design constraints_. It's boggles the mind that
you would consider languages that require compilers and aren't amenable to
semi-compilation and interpretation. (Remember PL/C? Those who do not
remember history are condemned to repeat it!)
Selfishly, I hope you continue your discussion because. As far as the
successor to the HP48 is concerned, though, HP should stick with a concise
and extensible architecture, and a fascinating departure from the currently
proprietary one would be a LISP interpreter upon which RPL is implemented.
(Imagine the possibilities!)

I could have given. The main reason I suggest it or Basic, is for the same
reason Barry Marks posted. I just need a quick and dirty solution to most 
of
my problems. I don't want to have to learn RPL or Saturn Assembler just to
solve my problem. I used to own one of the Radio Shack Pocket Computer's
(PC-7 I think), it had Basic built in. This was a great solution for me, I
had dozens of programs written for it. I didn't need to haul around a big
manual to do it either. I could just plug a little 15 line program in a few
minutes and have a solution.
  I understand that some people write very large and in depth programs for
the 48, but I think that a language like Pascal or Basic could just as
easily support that as well. If they really need the speed they could use
assembler like they do now.

Please understand that I wasn't suggesting Pascal replace RPL.  I'd much
prefer RPL in the calc.  I'm a C programmer and Pascal would be easier for
me, too.  But RPL is so much fun.  And I think it makes a lot of sense on a
calculator.

Seems to me that something like scheme would be ideal for the '58.
1) There is almost no syntax to learn
2) Polish notation should be easy for people used to the reverse.
3) It is easy to do interesting things with lispy languages.
4) It rewards good programming style.
5) The HP already has a garbage collector.
6) Garbage collection, garbage collection, garbage collection.

----------------------------------------------------------------------
 
2a) it's dead easy to do a reverse-polish version of Lispy languages.
The problems are really &REST args (in CL-speak), and the usual forth
problem that you are often kind of confused about whether to evaluate
a function or stuff it on the stack.
But the hp48 memory management is weird to Lisp people because it
doesn't really do what you expect. In particular the hp48 seems to
copy things a lot -- for instance when combining composites it seems
to copy them rather than just having pointers to the existing ones.  I
think this is to make GC easier and to reduce memory footprint, but
presumably a machine with 16Mb or something would be really cheap now,
and should run a Lisp comfortably.
--tim (from line may be bogus, I'm tfb@tfeb.org)
----------------------------------------------------------------------
 
That sort of copying forms the basis of one of the simpler GC schemes to
implement. For example, last I checked, the Gnu compiler, gcc, used a
similar algorithm for it's own internal memory management while building 
and
decorating syntax trees.

Steve
----------------------------------------------------------------------
 
It's important for a professional programmer to avoid poor programming
practices.  But someone writing a little something for their own use on
their calculator usually just wants to make things work.  Sure, the more
they learn the proper way to do it, the better.  But that's not the most
important thing for a do-it-yourselfer.
Barry

Not to defend these practices, but something to think about (numbers are
what I remember off the top of my head, they could be off slightly, but the
point is the same):

Quake - 128 gotos (reportedly)
Descent - 217 gotos

would help bridge the gap between calcuator and computer. Oh, I would also
make the ROMS downloadable to the 58.

And then, that's it, you would never be able to use the emulator again, 
unless
your either found and deleted the hidden file, or reformated your
hard-drive...( OR like a virus, the emulator would copy the time-file to 
any
system disks or back-up tapes that you allowed to come in contact with the
original or copy of the time file...??? (!)

    actually, i'd like to go back to some older models, like the 11C that 
was
MORE solid feeling, and had a nicer key 'pulse' (?)
b) smaller, bigger screen, fewer keys, more menus, easier to access menus, 
user
defined/orderable menus...( allow the user to redefine the menu access
trees...so instead of simply creating more menus, the user could customize 
the
user interface...( this however would make it very frustrating when you lend 

it
to someone...??? ))
c) colour with 300 pixels per inch resolution / with alcohol 
batteries...!!!
d) built in spectrum analyizer.
e) tiny camera that tracks your eye movement to act as 'mouse' controller.

mathematically correct semantic for it that would apply
to numbers as well as strings and string/number combina-
building up certain types of expressions.
------------------------:: o
this sounds like a good idea, but if they're going to add (Eeeeeeeek!) a 
new
catenate operator/function then perhaps they should use the ones already
available to Set Theory, and along that include some new characters for
Union...and uhhh...what ever else is part of Set Theory...
along with some characters/operators/functions for Symbolic Logic, allowing 

for
fractional logical values ( Fuzzy logic ) and the Set Theory operators that 

go
along with that...
as i suggested/mentioned several months ago during the Object Oriented
Fiasco...
whenever we say add or subtract or whatever, we are very often refering to 
many
operations with a single term...maybe HP should extend the Operator base to
include all the sub-operators as User level functions...or SubUser Level
functions...???...that is, 'rare' functions...???
they could be hidden away in a buried directory somewhere, and have limited
error checking, so that if they fail, they wouldn't fail catestrophically, 
but
only crash the individual program--while allowing the user to write, 
somewhat
less friendly, but much faster code...???

My HP48G with 256K WDT RAM is failing to operate a TV/VCR using Bjorn
Gahm's Remote 3.4 - using a setup that has worked previously. 
When I use the self-test (On-D), and press H, I see U_LB 20000. Is
that the IR loopback test? The batteries in the calc are a little
elderly - could it be that they're running out, meaning that there's not
enough power to operate the IR?
I can't handle the news traffic from c.s.hp48, but please post anything
to the newsgroup as well so other people can benefit.

It looks like hell because it has been sickly modified. I changed the
division ratio in the PLL loop to soup it up. Actually there are now 2
division chains in the PLL loop a HCT4066 quad bilateral switch it used is
switch between the two divides. The normal mode and my super programmable
mode.
The normal mode is needed so the ports work. The 4066 is turned on and off
by pushing the A and F buttons at the same time. The programmable divider
is also wired to the HP so you can program it with the keyboard. As I had
no idea how much I could trim the Saturn until it crashed. You can speed up
it up or slow it down with the + and - buttons. There is a little switch on
the side so you can can force the HP in to its original mode. I also wired
in 128KB.

In addition to Dave's answer:
If you like to group your CST-menu (to have some sort of directories)
you can try this structure:
{Name2 << {...}
 and so on (inlcuding the neccessary closing brackets)
Name
 is the name you want to give to the *directory/folder*, which you are
adding to the CST-menu
{...}
stands for your list of CST-functions (like for the normal CST-menu)
you whish to have in that specific first *directory*
Name2
is the name for the second *directory*....
Store the above list of lists under the name CST (like usual)
I hope answer is clear to you.
Happy custom gouping :-)

        This is all good.  One more question, though. 
Is there a way to put things like IF, END, etc. in a custom menu?
I now know I can put things like UBASE, UFACT, and so on.
I guess this is one difference between commands and syntactic keywords 
(what's the HP term for these?).
HP calls them conditional structure commands.
Several requests for clarification have been posted.  However, if what
you want to do is to use these keys as typing aids (i.e. you press the
appropriate key in your menu and IF is inserted into the command line;
would be useful for keying in a program), just insert the word as a
string.  Ex:
{ IF } 'CST' STO
It may be helpful to make it  IF , with spaces.
-- 
 
I'm not really sure what you mean by adding IF, END... to  a custom
menu. Do you want to call those commands from a custom menu, or do you
want to create a custom menu, that acts depending on a specific
situation?

----------------------------------------------------------------------
 
Anything you can put in a list, you can put into either a temporary menu
or a custom menu. What you will get from pressing the appropriate softkey
will depend on what kind of an object it represents. Commands will act
like commands, etc.
----------------------------------------------------------------------
 
  Anything may be included as a typing aid (i.e. a string)
  in a list argument for [T]MENU, but you will find that
  a list such as { IF END } [without quoting each individual word]
  will produce an Invalid Syntax error; the list { IF THEN END }
  you will find that it contains only one object (a program
  containing the entire structure IF THEN END); also, a [T]MENU
  command will produce nothing useful from such an argument list.
  That's the way the built-in UserRPL compiler treats such words;
  it is not willing to leave any incomplete structure just
  hanging there by itself, so it requires the structure to be
  complete, and it also embeds it within [an invisible] program
  object, which is a common thing done by the compiler for
  various other needs as well.
  However, the list { IF END } is perfectly acceptable
  for creating menu keys which serve to type their strings
  into any current command line text; no surrounding spaces
  will be generated, however, unless you include spaces
  yourself within the strings.
  It takes a bit of SysRPL, alas, to create a menu containing these
  words so as to have the exact same utility as the built-in menus.
replace the IF label here with a 21x8 grob showing IF like a directory
label, youre quite close. I know you know, but others don't ;-)

No problem: Extract the ROM of your HP48 with ROMDUMP, which should be 
provided by the Emu48 package.

Are there any special measures that must be taken to successfully dump
the ROM?  I tried to use the RomDump Wizard; it appeared to start the
process okay, but quickly sent my 48GX into Recover memory? mode.  I
had to do a paperclip reset to get it going again (not to mention
reload all my custom software).  I've got a program card and 512k RAM
card in it, if that makes a difference.

Just use the romdump wizard that comes with
EMU48 to download the ROM from your OWN HP48...
 
----------------------------------------------------------------------
 
I too downloaded EMU48.
But I am very leary about dumping my ROM when the install instructions
suggest 2 .dll files are missing. Also there are extra files that are
recommended for download that conflict with existing files.
I opened ROMDump and it just laid there.......
It seems that EMU48 is very popular, so I must be missing something.

Not sure what the best one is, but my favorite so far is Hp-Ymodem2.2 by
Laurent Bernard.  It's super fast and very reliable.  You have to run it
through Dos, though, and no graphical interface.  The link is below.  Give
it a shot and let me know if you need help with some of the syntax.

It works fine on some computers (486DX2/66, 486DX4/133, P/200, P2/233,
P2/333). All needed Emu48 modules (Emu48.exe, ROM.48G, *.KML, *.BMP,
(BEEP.EXT)) must be in the same directory. Check and/or Convert the
downloaded ROM with the CONVERT.EXE utility deliverd with the original

To anyone who has experience in the Cris Ramos' c-compiler ( Th216 C-
compiler ). Does anyone know if it is possible to compile any C-program, 
world!/n) is a lot different. It includes a lot of code to do the trick. 
I have the code which came in the examples directory of the C-compiler of 
his site. I also investigated the entire newsgroup for the subject of 
hp48 c-compilers but I have found nothing interesting.
----------------------------------------------------------------------
 
About once a month someone asks a similar question.  The best answer I have
seen was posted recently.  The problem is that there is no stdio library 
for
the compiler.
----------------------------------------------------------------------
 
This has to do with the fact that printf is not really part of the C
language, per se, but is just a function in a library of functions (often
written in C) for doing terminal i/o.  The HP48 is not really set up to do
input output in the same way most desktop type computers are, so things like 

printf are not as simple as it might at first seem.  There is a lot going on 

-- under the hood -- when you run the C one-liner int 
Checking out the size of the executable it creates on a normal computer will 

give some idea of the hidden complexity.
Consider, also, that while the computer in your vcr or nintendo may have
been programmed in C, it is doubtful that printf would have much meaning in 

this context.
-- 
Steve
----------------------------------------------------------------------
 
like
I don't know how to do it, but I think that a minimal printf function would
be feasible.  I write C to automate simple but laborious calculations used
in an engineering office.  With *basic* IO functions (and data types)
available for the HP, I could port them, instantly.  There are several
programs that must be on the PC, but would be great to have on the HP as
well (I'm considering a palmtop for this reason, reluctantly).
If someone wanted to take on this challenge, I think we would see a wealth
of new useful HP software by users who have C code to share.  I, for one,
would be much more willing to share my code with a specialized group of HP
users, rather than upload a Windows .exe file to the world at large.
 
----------------------------------------------------------------------
 
A beta means a test version of software, that is not supported in any 
way.
It is a normal method of testing software, you make a pre-release copy of 
it
available before it is finished so people can find the bugs for you.
And, an alpha generally means a version that is just barely ready for 
use,
and has gone no testing whatsoever.
Hope that helps!

I just think that this Emu48 Unofficial update IX is wonderful.
Now everybody is able to run all games such as WarioHP land 3.1 250

The big improvement is the fake48 speed I think.
I'm very happy to use such a great program on my computer!

Agreed, great idea.  Speaking of new HP's, what about a built in, cheap,
replaceable scratch protector for the LCD?  This would be a valuable asset 
since
many HP's probably wander into the lab or workfield, not just the office or
classroom.  And then you wouldn't have those ugly elastic bands.
