DONıT OPEN IT, HOW CAN CURIOSITY BE CURED??The hp49G+ was
made to be opened, it is very easy.Open your battery
compartment. You will see two round plastic rivits.Use a
razor blade and cut them off ŝush. They can be easily
replacedwith screws later, and are not even mandatory. Next
use a small knife,or Ŝngernail, and seperate the dark plastic
band from the bottom halfof the calculator. Do this starting
up near the USB port, and workingyour way around the
calculator. You will probably notice a slight gapin the trim
piece up near the USB if you look closely. The calculatoris
snapped together during assembly, with the bottom half
snapping tothe top half. I have had mine apart 20 times and
the snaps still gripand release like new. There is nothing
more to opening the calculator.With dissambly this far, you
can install a switching type DC powerjack (I have), and even
connect a LED (I have)in parallel with thepizo buzzer. This
is also all the further you need to go if you areone of the
people that bent a contact inside of your batterycompartment,
and you want to make a repair. Also, if your SD cardsocket
would ever wear out from heavy use, you can order the part
onthe internet, and solder it in yourself. I absolutly love
my hp, and it seems to me that someone took somewell planned
design considerations regarding repairability. Theseunits
could be repaired by most any dedicated amature, and
mostdeŜnatly anything could be handled by the factory. But
quitehonestly... at $150.. just buy a new one.If you desire,
after this stage of disassembly... there are many morerivits
that you can razor blade away if you want to see the other
sideof the board!!!John Evers>> Does anyone know how to open

partly agree with Aagje. Even in Assen (non-universitycity in
the north ofThe Netherlands) I could get a new 49+ (1.23!).
However, my supplier toldme that he did business with a
company in Belgium. But it isnıt unusualthat just one company
in one of the countries Luxembourg, Belgium or TheNetherlands
is importing stuff for the others because of the small
marketsin each of them. Strictly spoken, the second statement
of Erwin is right. This doesnıt effectthe availability of HP

I thought the problem may be with this two programs. But I
donıt knowIım not familiar with them, but if reinstalling the
USB driverand Conn4x after extracting the Ŝles
fromHP_ConnectivityKit.exe doesnıt Ŝx things, if theyıre
libraries,it might be worth a try to bypass their
conŜguration oruninstall them.Which operating system is on
the PC?If all else fails, if itıs feasible to disconnect
other USBdevices from your PC, you could give that a try. I
eventuallyfound that my Serial to USB converter was causing a
Blue Screenof Death when used at the same time as Conn4x, and
updating theconverterıs drivers Ŝxed the problem.--

Juststore your library in any other port (it doesnıt matter
which one),and use port number 3 for all variables that you
want that library tocreate in the SD card.Variables and
libraries need not be in the same port; in your case,they
cannot be in the same port.If that doesnıt answer your

BSD-style license, so HP technically doesnıt even need to ask
me to do so, although that would be nice of them. In actuality
though, integrating somebody elses basically un-commented code
would be rather challenging without direct input from the
author, in this case me. As it is, most of it is four years
old, and I still canıt Ŝgure out what a few of the commands
even do, which is something of a problem, since I am trying
to complete the documentation.Since they generally will
evaluate to another trigonometric relation if you use them
symbolically, they will integrate and differentiate. For
example, << ŒXı CSC >> would evaluate to Œ1/SIN(X)ı, and so
it would integrate, differentiate, etc.The only major issue
is with the equation writer. For some reason it will not let
me enter CSC(X). I can type in CSC, but it just beeps at me
when I hit the () button. I never use the equation writer
myself, but I am sure that other people do. Does anybody know
how to easily get the equation writer to allow a function?
These are all written in User RPL, and turned into a library
via CRLIB on the calculator.====> When scanning for keys

interrupt.The reason the interrupt are disabled after youıve
performed ST=0.15 (the ofŜcial name of this ŝag is
sALLOWINTR) is because it is checked by the interrupt handler
which will do a simple ReTurN instead of doing a ReTurn
Interrupt (RTI). So hardware-wise youıre still in interrupted
mode so no new interrupt can be generated.The only way (and
ofŜcial) way of re-enabling the interrupt is to call the
entry point =AllowIntr.In your particular case, youıre lucky
that your calculator works again because one of the Ŝrst
thing the kernel does is to re-enabled the interrupt (it
would have been a different matter on the 48G!)But try

#1000000000000000b. I know the> program is written horribly,
but still.Youıre missing one important point. in fact maybe
two.Doing INTOFF will not prevent the interrupt to happen,
just that a keypress will not generate an interrupt or other
maskable interrupt. Clock, ON key etc can still occur. If any
interrupt occurs the keyboard will still get scanned.This is
the reason why even though you speciŜed a OUT mask you still
get to read when another key is pressed.When the interrupt
handler scan the keyboard itıs changing the OUT mask in order
to scan all keys. Once the scan is completed the interrupt
handler will restore the OUT mask stored in the reserver
memory.So in theory, your program is dirty (tm) Before
changing the out mask you should Ŝrst change the =ORghost
variable, then perform OUT=C.That way you can be sure the OUT
mask will not change without your knowledge, or more precisely
it will change but will be restored at the end.If you perform
ST=0.15, then you wonıt see the problem. But forbidding
interrupts is not always a good thing. You can endup with a
very inaccurate clock if you do so.====> Is there any

Original Question------------------------------I just
purchased a 49G last week. So far, I donıt know how I ever
gotalong without it!Iım starting to write small programs, but
noticed an annoying problem:Page 10-3 in the manual says that
if you invoke a program youıve savedby pressing its button
from the ŒVARı menu, parentheses should beinserted for you,
ready for your arguements.This *never* happens for me, I
always have to enter the parenthesesmyself. Iım disappointed
because it would be a great help. Perhaps Iımdoing something
wrong, but I havenıt been able to Ŝnd any info aboutthis
on-line...Can anyone help me? Maybe this is a know bug and I
just need to upgradeto ROM 1.16 (they shipped mine with
1.10).-Chris====> Happy new year for all.>> There was The

then,> Is there no other way?> Nobody can make udf that
warking just like Œ1/xı.> (Is this limited by OS?)XYes====I
want to thank you all for the input on the SRECV
question.Iıve done a bit of testing as James suggested
between devices (Emu48 and a48gx) and found that DOBUFLEN,
GETSERIAL and PUTSERIAL are sysRPL commands forBUFLEN, SRECV
and XMIT. Well, maybe. I donıt know if GETSERIAL or
PUTSERIALwill send Xon/Xoffs if IOPAR is set for pacing.
There is also the commandDOSRECV which probably does mimic
SRECV in the sense of having a pacing option.This is not
important now; since the 49G doesnıt have pacing, I canıt use
it. Istill might need to make my own form of Xon/Xoff.As a
side note, James noted that the Xoff and Xon signals just
toggle back andforth in SRECV pacing. This seems to mean that
the sending device does not haveto decode the signals, it can
just toggle between On and Off upon receipt of astart bit. Or
so I think and had planned to use in my device since it
savestime and hardware.The testing has also allowed me to
begin to get a handle on the timing issue.However, additional
testing has been put on hold until I Ŝnd out how to do
anindeŜnite loop in sysRPL. The instructions in Kalinowskiıs
book are simpleenough - BEGIN <loop clause> UNTIL where the
loop continues as long as theloopclause returns TRUE - but
for some reason I canıt make it work. The formBEGIN <test
clause> WHILE <loop clause> REPEAT does work using the
originalloopclause as test clause and a NOP as the loop
clause. Sigh. I hope to havetime this evening to Ŝnd out what
is going wrong. If unsuccessful, I willstart a new thread
asking for help on that since it might be of
generalinterest.By the way, the device Iım building is a
simple data logger. It stores a timestamp in memory (8k
bytes) whenever an event (a 3v pulse) occurs. It
willinitially be used with a rain gauge, an Œeventı being
when 0.01in (or 0.1mm) ofrain has fallen.Again,
thanks.Robert====> Lithium batts works Ŝne for a short time,

learning rpl now and my handbook already now (afteronly a day
or 5) looks like I have used it for a year because I very
often needit while learning rpl. Itıs a Ŝne and really very
powerful language with whichyou can do very much, if not
almost everything. (Well, it doesnıt make a cup oftea though,
but apart from this lack of functionality it satisŜes many of
mynumerous needs) But I think sometimes that the syntax is
somewhat overdone. Ithink that things sometimes could be a
little easier. I mean: The input commandfor example is
something like: Type 2 numbers {:A: :B: {2 0} V} INPUT
OBJ->-> A B Yes, I think this can be simpliŜed among other
things. Itıs confusing.Also the INCR command works strangely.
I all the time get a Bad argument error.Also itıs a very
tiresome task to compute an improper integral with the 48G.
ButI can manage this.Well, maybe in may or so Iıll head to
the shop again to buy a 49G+ and use my48G on the road. Then
I have a powerful computer (the 49+) at home and a
decentcalculator (the 48G) whereever I need it outside my
place. Aagje====> ... Also the INCR command works strangely.>
I all the time get a Bad argument error.INCR only allows an

ŝickering.However, the colon giving the seconds in the clock

I agree. Besides the noisy keyboard (I almost got killed
bystudents in a test, having angry looks saying :how much
noise do youmake....) the calc is really great. I tried to
return to my oldhp49g, and after 10 minutes I put it back
into the drawer, thinking tomyself: how did I used it for 4
years ?I just hope that the ŝickering issue is solveable with
the new ROM...Happy New Year everybody !

Cole====I have not used HP-IDE lately, but from the sounds of
it there are one oftwo problems:1. You have not installed
SASM.exe the Saturn Assembler, i think that youcan get this
and other tools from the HPGOODIES disk 4. (which is
deŜnately onHPCALC.org)2. You have not set the correct paths
from HP-IDE to the dir in which SASMis located. Iım not sure
exactly how you go about doing this (SASM may even need to be
inthe same directory as SASM) but read the readmeıs, they will
say for sure, how and where toput
everything.M@------------------------------------------------

free to use the more convenient HP function ASINH(X)

times.Some friendly advice: if the calculators canıt
integrate a functiontry a math package like matlab or
mathematica so that you can bereasonably conŜdent that you

do this integral it seems that you may have to be creative. I
usedintegration by parts and designated:u=
ln(x+(1+x^2)^(1/2))dv = dxThis can be done by hand but on the
hp you will write in RPN mode:level2:
ln(x+(1+x^2)^(1/2))level1: xIBPWhich yields:
x*ln(x+(1+x^2)^(1/2)) <--- this is u(x)v(x)
-x*sqrt(x^2+1)/(x^2+1) <-----this is -uı(x)v(x)Then you need
to integrate -x*sqrt(x^2+1)/(x^2+1) again to
get-sqrt(x^2+1)Finally you can add these two together to get
x*ln(x+(1+x^2)^(1/2))- sqrt(x^2+1).====> OK THnx for the

Daniel====am looking for a tableof Rom Libraryıs/Commands for
the DOROMP SysRRLl object.In more detail:AFAIK, the DOROMP
object takes two arguments, the LIBRARY ID and the
COMMANDID(both 3 nibıs) I am working on a diss/assembler for
Aplets/E-leasons for thecalculators and would liketo Ŝnd a
table (or similar) documenting the librarys and thier
commands.For instance, I know that library 002 conains
commands like 036 (+) and 039(-) etc, but I have found these
out by manually decomplining symbolicobjects of known
composition. I would rather not have to go thorough theenitre
compliment of the calcs functions since Iım sure that I would
forgetsome. Is there anyone who has an entire list (ie not
just lib 002)

Those HPıs are likepeople. Iıve begun to love them.But HP has
a smart marketing strategy... They Ŝrst come with a buggy
HP49G andas soon as many people bought it they come with a
better HP49G+.Soon everybody has that one and then theyıll
come with a certainly again not yetperfect HP50G and then the
HP50G+ etc...So for the time being Iıll stay with my beautiful
cute HP48G although I agreethat a 48G+ would be a little bit
better.But thatıs just what they want. This way they can be
sure that once Iıll buy anew HP. Or not: Because HP users are
smart people and understand theirstrategies.So the memory is
already there. The speed not yet, because they
deliberatelytake it easy... HP invent i read somewhere
lately. Iım waiting for it! Ichallenge them all. Aagje ====I
have 2 questions:1. When I connect my 49g+ USB port to my PC

pagemanual but havenıt found a fool-proof way of turning off
the port. I amunsure if it is waiting for a time-out or
something. Pressing ON or turningoff the calculator does not
stop the communications indicator.2. Is there a how to or FAQ

Fred Valdez, head of the HPcalculator division. It is mostly
about the 12c, but there is a lot oŜnteresting information in
it.Some choice tidbits, and then the link:intuitively RPN is a
lot more straightforward, and I think once peopleuse it and
understand it, they will realize that RPN is truly an
easierentry mode.The other thing is that thereıs a kinetic
experience with our 12c. We havewhat we call the Œrotating

press the keys. People look for that; they seek it,
theydemand it, so itıs more of a personal experience with a
