Greetings! I have a project in the *very* early stages of
development. Ineed one or two **dead** 48G series units.
Occasionally eBay has some butnot very often. It would be a
criminal act to sacriÞce a working unit so isanyone willing
to part with an old deceased friend?I¹ll pay shipping in the
US via PayPal.Doug StarwaltAnderson, SCIT does not equal IQ -
Starwalt 1999====> 7.New functions - didn¹t Þnd any yet
(compare to hp49g rom 1.16)Of course - just a small typing
mistake - should be : compare to hp49grom 1.19-6.
sorry.Idan====I bought a new hp49g+ recently (1 week).
Yesterday i updated the romto v1.22. Today i noticed that a
vertical line more bright (2 pixels)appeared in the lcd (
1.5cm from the left of the screen, more orless). I don¹t know
if the line appeared right after the update oronly
today.Sometimes the pixels of that line behave normally (not
in many cases),other times they appear like a shadow , and in
some cases they don¹tturn on at all.When I¹m putting the
contrast to the maximum the pixels on that linebecome black
latter than the others (so the vertical line is
clearlyvisible), but in the end all the screen is black and
no line isvisible (with good batteries).When I perform the
lcd test one of the vertical lines doesn¹t appear,but all the
horizontal lines seem to be ok.I have reinstalled the rom but
the problem stills. I don¹t know whereto Þnd rom 1.20 (?) so
i haven¹t tried to install it again.Does anyone have this
problem? Its a software problem or hardware? Ihope is not
hardware because the calculator was bought in the USA andi
live in PortugalAnother strange behavior: Some days ago when
i was plotting a function(fast 3d, rom 1.20, and rechargeable
batteries 1.2V) the calculatorturn off and it only turned on
after a reset...Cn33302053 on the back of the calculator.Any
help is welcome.Carlos Jorge Francisco====> Another strange

turn off and it only turned on after a reset...If you have one
of the early models of HP49G+, in case of Very low battery,you
will need to perform a reset to restart the calculator.This
was done because the VLB is only tested around .5 after the
resart ofthe calculator in the OS, so, if you have a calc
with very low bettery andpress on the ON key, repetitly (if
it is in a bag that is getting stamped onfor example), you
are likely to loose data...in the later version, some testing
was added in the boot loader, making theVLB testing imediate
and allowing to remove the forced reset...====X> in the later

this may be an RTFM type question but....I want to integrate

Then INTVX instantly gives SIN(X)-X.COS(X)Erable 3.2 gives
the correct response in either exact or approx mode.Well,
actually, INTVX returns (-X)*COS(X)+SIN(X) but EXPAND
pretties itup into SIN(X)-X*COS(X). Since the 49 CAS is based
partly on Erable,I wonder what¹s happening here; perhaps
Erable silently switches toexact mode for INTVX and then back
to approx when it¹s done? Or maybeit ignores the exact/approx
þag altogether. (INTVX leaves it in approxmode, but EXPAND
switches it to exact.)-- Wayne Brown (HPCC #1104) | When your

buzzer is directly connected to one of the IO pin ofthe CPU,
the power is limited by the output of the CPU which is
saddlyenough only 3.3V at fairly low intensity...so, sound
level can be controled on a piezo buzzer, however the
hardwaredesign of the calcualtor does not make it
possible...Even putting an ampliÞer is not feasable as the
power supply for thecalcualtor is also 3.3V... (and direct

General====If that is the cause, then some non-conductive
insulation squeezed in> between the PCB and the back case
should help a lot.> For a quickie test, I tested the
calculator (it came on & turned offjust Þne), took off the
back case, stuffed some sliced-up foampeanut packing material
betwixt the PCB and back case, shut the thingup, and it
wouldn¹t turn on. Either the pressure on the PCB causedsome
problem, the foam got in the way of some contact (I don¹t
seehow), or the batteries coincidentally happened to go dead
at thatmoment.Before returning things to normal, I tested the
keys for noise -- Iwill say that the keys sounded deader --
they were perhaps just asloud (or nearly so), but didn¹t
sound as hollow. It was a noticeablechange, but I¹m not sure
a signifcant one.Anyway, I took out the foam, it still
wouldn¹t come on, but replacingthe batteries brought it back
to life. Presumably, the batteries wereat fault. (But that
was one heck of a coincidence!)====> ??> 5) the alarms issue

have used a User RPL program called WalMn (for Wallet
Manager)that manages my wallet. It is quite effective and for
certain people witherratic spending habits (including myself)
it can be a life saver. TheStart screen of WalMn has the
following entries (in two columns, shownhere as one column)
which can easily be modiÞed:A AutoC ClothesE EntertnD
meDicalF FoodG GiftV VacationH HygieneM MiscellanP ProfessnR
RecreatnT TransprtU UnaccountedY YogaW Withdrawl1= NXT(The
NXT screen has many more entry possibilities).So, for
example, if one presses the F key (Key 16.1) the next screen
comesup and asks for the amount of Food expenditures. That
amount issubtracted from the current balance and stored in
the account Food as avalue subtracted and balance for the
current month.When I withdraw money from the bank I enter it
by pressing W, and thatvalue is added to the current wallet
balance.At the end of the month the GtTot (Get Total) program
adds everything upand stores it in a variable TOTL as an
array. TOTL can easily imported intoExcel where it can be
further manipulated to suit ones personal accountprogram (if
one has one). The RESET menu resets all the accounts to [0.0.
0.] at the end of the month.I always know how much is in my
wallet, and mindless spending and/or falsechange by merchants
have been minimized or excluded.My next task is to convert
this program to System RPL (which I just startedstudying - so
it will take a while). Anybody interested in using WalMn?

routine pressure changes, the seals \on two (both) brand-new

couple of questions: 1) Are the \Renewal\ cells the same as
the \IC3, 15 min. \Rechargeables\? 2) How are the unique form

These don¹t seem to be made in anything close to a standard

most likely be an emulator on a PDA...I thinkthe best of both
worlds would be a hp49+ add-on keyboard to aminiature iPAQ.For
now I think HP¹s focus should be directed towards perfecting
the49+¹s keyboard.====I think most of you want a computer
instead of a calculator. Thatswhat a PDA is for. If you want
a PDA with an HP-49G emulator, buy aPDA and download an
emulator. Then you will have all the extra memoryand speed
you need for all the things you want to do which
calculatorswerent designed to do. I know we¹ve convinced our
calculators to doall sorts of things (play games, be an
organizer, let us makeprograms) other than what they were
designed to do (solve equations,help us visualize graphs,
CALCULATE), but that still does not changethe fact that these
are calculators. It is true that a fasterprocesser will help
us solve equations faster and more RAM(surelythats what you
mean, I cant imagine someone asking for more memorythan an SD
card holds) will allow us to manipulate bigger matrices,but
what real need is there for more than 512kb of RAM?
Whatcalculations do you do which are not fast enough to suit
you on anHP49G+? If another calculator comes out which will
help me do thingsbetter than I do them now I would consider
buying it. But I meanexactly what I say, I would buy another
CALCULATOR, not a PDA. I hopeand believe that the successor
to the HP49G+, a calculator, will be acalculator.====> I

are right. We are talking about calculators, but I want to
use it \as acomputer. I must be able to do powerful things
with it, solve matrixes, \programcomplex formula¹s and
evaluate them. I do NOT intend to play games with it, \I
donot intend to use it as an organizer and so, I want to have
a pocket \computer,not a calculator. And yes, I want to
program it, but I¹ll only writemathematical programs.That¹s
why I don¹t like the plan of a pda with an emulated HP 49G,
because \sucha complex machine can¹t be emulated in a pda.A
pda is a pda, a 49G is a 49G (and a 48G a 48G).And you¹re
right, 512kb of RAM is more than enough, even 128k wil do.
For \now Ihave 32k and it¹s enough, although i foresee that
once it won¹t no longer. So let the 50G be a calculator with
the power of a computer, but only with that part of
computerpower that can calculate. And let they give it a
decent \keyboard, for example that of the 48G.Aagje====what

Carsten====I live in the Netherlands. I ordered my HP49G+
from Eric(www.hpcalc.org) and got it eight days after I made
the order. I paidno duty, so it was a *huge* saving over
buying it in Europe (USD 160including postage vs Euro 205). I
also bought two HP10BIIs from SamsonCables and received them
inside of two weeks, also not paying anyduty. Even if you do
pay VAT, it is still considerably cheaper.DifÞcult to return
them if required, that¹s the risk you take. Ihaven¹t had any
problems.You can buy calculators here. However, they are
expensive because HPsells via a Benelux distributor (in
Belgium), who then sells to theretailers, and in my Eindhoven
experience they don¹t have them instock anyway. And they
wonder why there are parallel imports ...Tim> In The

need a number? Why??Yes, for speed. If libraries only had
names, then calls to theircommands would have to perform a
name search through potentiallydozens of libraries, resulting
in slow program speed. Worse yet, themore libraries you added,
the worse the problem would get.The existence of Library ID
numbers solves this problem. Everylibrary has its own unique
number (ideally), and each command in alibrary has its own
number within its library. Thus every command isuniquely
identiÞed by a pair of numbers, e.g. XLIB 123 456
means\command #456 in library #123\. Since the machine keeps
track of thelocations of all attached libraries, an XLIB call
can be resolved inalmost no time at all.That¹s why library
calls are so fast, and why libraries have numbers.-Joe-====>

gains speed - convenience forprogramming the compiler, maybe
or the OS...But Forth systems use numbers, compile words to
pointers and are quitefast...A dictionary of library names
and locations which the compiler usedwould be just as fast as
a number (since the library number is not thelibrary¹s
location, just an identiÞer (that may be 10.5 bytes? inwhich
case a ten letter name would be just as fast...)Pete M.
WilsonGamewood, Inc.wilsonpm@gamewood.net====> Does a library
really need a number? Why?? That seems like rather bad
\design.Libraries on the HP calcs are used as containers of
commands (as youprobably know). Libraries and the commands
within can of course havenames (they often do), but the
single unique property of a library isits ID number.I write
\can\ have names, because you can have a null-named command
ina library for example - this command won¹t show up in the
librarymenu, and the only way to access the command is by
referencing it fromanother program by its library and command
number. Library numbers000h through 300h are reserved for
internal use on the HPs - as arelibrary numbers above 700h
(other IDs are used by the system as well).Only the directly
accesible commands have actual names, as the OSdon¹t need
them. If a programmer knows in which libraries to hook, heor
she can access normally inaccessible internal routines with
apointer.Lists of all internal commands accesible this way
exist, but to lookfor yourself, Wolfgangs Libman library is a
big help.An example: Library 2 contains most of the basic
commands in theHP48/49 (there are 401 commands in it). This
library doesn¹t have aname, since it¹s an internal library.
Command number 82 in thatlibrary is the SIN function, and
this function can be run in a SysRPLprogram with this
statement ROMPTR 2 81 (there are other pointertypes, PTR,
FPTR2 aso. depending on the location of the command ordata).
Now, it would be easy to access the sine function in a
programin a more normal fashion, but then consider this
example:Library 788 contains many of the CAS commands in the
HP49G+ (there are1444 commands in this library). Only the
Þrst 141 commands in lib 788have names (like EXPAND and
DESOLVE) and are thus accesible via thenormal command
interface! The other 1303 commands can be accessed inSysRPL
via rompointers as above. Not all of these are
documentedthough - maybe half of the complete set of unnamed
commands are.I have currently access to 5875 library commands
on my HP49G+. Comparethis to the 1059 commands available
through the catalog :-)Oh, I almost forgot; The HP uses
pointers instead of names to accesscommands, because it is of
course much faster.====> What would be better? A name? So then

this on your 48:1) RCL each variable and then ->STR and STO
back2) now you transfer them to a PC3) transfer to your
49g+4A) RCL each variable and then STR-> and STO backThere
are better ways, if you use Google to search this NG====It¹s
even easier if you did the abovementioned procedure with a
wholedirectory instead one variable after anotherJust recall
the directory in the stack ->STR, give it a name, send to
PC,send to HP49G+ (or better use the SD card), put it in the
stack, OBJ-> andthat¹s it. Works ok. :)> One solution is to

instead> When doing [TOOLS] and [NEXT], you get F1=CASCM and
F2=HELP.Not a bug. When CASCMD is called with an empty stack,
it performs thesame function as the HELP command. However,
when stack level 1contains a string, then CASCMD jumps to
that entry in the HELP table,unlike the HELP command, which
never takes any input.-Joe-====Do you know how to transfert
Þles between my hp49g+ and myTanguy Briancon.My dream: a
program on the hp49g+ that made the calcjust like my external
usb drive! -:)====I tried my Grobedit(V 2.6) on my new
hp49g+.It \almost\ work (I used only supported entry points)
in B&W.I geta problem with the menu screen. I use the
addresses in the I/O ram(#130 and #128) to control the adress
of bitmap and the size of themenu and it doesn¹t work. Anyone
knows what changes in the I/O ram(in particular for the menu
bitmap)?I have also an other ASM question:Do you know how to
write in ASM in the bitmap of the header?Tanguy

where can i Þnd manuals for the hp49g? i can only Þnd manuals
forthe hp49g+ on the support site.thanks.====I have produced
two faceplates for Emu48 that resemble the hp 49g+. They are
not exact reproductions of the hp 49g+, but rather
hp49g+-like faceplates for the hp 49g emulator. Please notice
thatthese faceplates and their accompanying KML scripts are
the product ofmy Þrst-ever exercise in KML script
development, therefore, they arenot the hp 49g+ emulator that
everyone in the group is expecting, buta rather crude
approximation.The faceplate bmp¹s and KML scripts are
included in the zip Þlereferred below. I also included two
versions of version 1-19.7 of thehp 49g Rom (one that shows 5
lines -- i.e., similar to the hp 49g andhp 48gii -- and one
that shows 7 lines -- i.e., similar to the hp49g+. Please
notice that in the latter, the status lines are notshown).I
couldn¹t Þgure out how to move the functions CAT, Œ, EQW, and
EVALaround the hp 49g+ emulator keyboard, so I had to modify
the hp 49g+faceplates to look more like the hp 49g. Maybe
someone who reallyknows how to develop KML scripts will be
inspired by my crude attemptto the hp 49g+ plate and produce
the deÞnitive hp 49g+ emulatorfaceplate.Also, if anyone has
Rom 1.22 available for Emu48: I will love to gethold of it>To
