Just relax.  Christophe Nguyen was planning on posting all this stuff,
but it turned out to be a longer process than he had anticipated.  I helped
him get TRON finished, and then he suddenly lost access to this newsgroup.
I am not sure what state the other games are currently in, but you will

	I got the connection between my HP48 and the IBM worked
yesterday.  However, I experienced some problems with it.
In order to maker sure that the transfer will do a safe job,
I tried to load the pacman.dir from HP48 to computer, and
the computer to my VMS/VAX account, then reload them back
on my HP48 by using ASCII fromat in I/O setup.  However,
when I loaded them back, pacman would show the startup screen,
but fail to run, displays "bad argment...".  
	So, I was wondering, do I have to ASC-> a program everytime
when I upload it to my computer and use ->ASC to decode it, or can
I just use ASCII without doing any other changes? (notice that
when I transfered the sting "sin x^2" from HP48 to computer and
back, it worked just fine.  I don't understand what's wrong with
a directory like pacman.
	Any help  would be greatly appricated!

    Actually, Eveready (I think, some big battery manufacturer anyway)
    announced a 1.5V AA size lithium batteries about a month ago.  I would
    presume that there's some funky chemistry going on inside the cell,
    different than that of "normal" lithium cells.  They claim it lasts just as
    long as what we're used to in lithium, though.

These cells were reviewed in Popular Photography a month or two ago.
They seem to win over alkaline cells mostly at high current drains.
For a calculator, they wouldn't be much of an improvement.  I haven't
heard of any being made in AAA size.

    They also announced that they're going to mass-market AAAA batteries,
    which'll be useful.

AAAA cells are already available, just take apart a 9 volt alkaline
battery.

Hiya folks, 

I've got a cable for my HP48SX to my Apple IIGS, and a friend would like
to purchase a cable for his MS-DOS.

I see two cable packages available:  

One is a developer kit bundle, with software and a cable.. What exactly
does the software do?  Does it act as a microEMACS or something like that,
or does it have a transfer program included with it?

Also, I see just a cable listed at Elek Tek, I'm guessing that's simply
a cable for the HP and nothing more?

Thanks! :)

>Thanks.

Standard DB-25 and DB-9 RS-232 connectors have a shield pin on them.  It's
pin number one on both connectors.  (The shield pin should connect to the
braiding of foil wrapping on your serial cable; EM fields crashing into the
metal braiding or foil are cancelled before they hit the inner conductors
and induce noise.  Thus, the braiding or foil "shields" your signal from
noise.)

Inside the HP-48, the shield pin is AC coupled via a capacitor to the
HP-48's ground.  This has to be done because many PCs use the same wire for
the RS-232 ground and shield, whereas the HP-48 uses it's +4.5V supply for
it's ground pin.  Connecting the two together at DC would make sparks
fly... :-)

Keywords: HP48 innards Alonzo memory

I am starting to explore the internal operation of my 48, now I have over a
years experience in "normal" use. I have pulled a number of files from 
seq.uncwil.edu, mainly innards by Alonzo Gariepy and Internals by Derek Nickel.
Both are excellent insights into internal operation but...

I am confused about the Memory Layout, and modification of the layout in the 48
internal memory scanner mode. My 48 does not agree with Alonzo, in that the
first object in HOME is near memory address FFFF0 (in scan mode). I have
labouriously decoded manually my memory in that area, and identified that
it contains part of my directory structure, deep in the tree, not HOME.

Also, Alonzo mentions that the address of the screen's second line in scan mode
is F0A8C. Experiments make me think that it is F0AA4 (screen mode, not plot!)

I suppose my question is,
1. What am I doing wrong, Alonzo and Derek's work is detailed, I can't fault it,
   however these inconsistencies make me very nervous.
2. I am using HP48 rev E with 32K extra RAM in the slot closest to the screen,
   would this make a difference?
3. Where can I get more information on memory structure?
4. Where can I get more information on machine code programming for the 48
   either actually on the 48 or on UNIX machines?

one, and/or don't plan to buy one really cannot give an ACCURATE opinion of
whether their Casio, or TI is better than an hp48 and should not keep dragging

I just started development with RPL48.  My fist question is about WHILE
syntax.  RPLCOMP manual says that their compiler automatically puts the code
between WHILE and REPEAT in an object, ie WHILE <stuff> REPEAT is compiled
as WHILE :: <stuff> ; REPEAT.  Does the RPL48 compiler do that as well?

Also I'd like to do "DEFINES" in sys-RPL.  Currently I'm includeing
the EQU statements between ASSEMBLE and RPL directives, but that puts
an empty code object in the compiled program.

Is there a "good" list of sys-PRL commands in the RPL48 compiler.
I'm using the RPLCOMP manual now but find its index lacking and orginization
poor.  I'd like some kind of quick reference guide.

Finally, anyone have a list of array commands in sys-RPL, such as the
equivalent to IDN, TRN, array multiplication, addition, and negation?

Yep, New Media specifically told me that their interface is proprietary

The HP-95LX apparently does have a Type II cavity.  However, the only
internal jack I know of, the "X-jack", is patented by Megahertz, so you
probably won't see that on anyone else's modems.  Considering the
breadth of patents these days you may not see any kind of fold out
RJ-11 on a PCMCIA card.  Maybe the card attachment is rigid enough
for a module rather than a pigtail cable?

UWO has had (in courses I've taken) several different policies and problems
have arisen

1. Engineers are required to own HP48's.
   -this happened a few years back and profs have adjusted their exams to 
    reflect this (average on first year calculus is still mid fifties)
2. Statistics/Actuarial science doesn't allow programmables at all.
   -last year on a numerical analysis exam, a student protested that some
   classmates had programmed the entire exam into their calculators (very
   easy to do, although I didn't have my HP then :-)

3.  Stats/Act Sci states that the only acceptable calculator is the equivalent
  of the SOA calculator.

Several of my own points of view on this
a. I learned RP to use my HP (which was required for the engnrng math I took)
   so why should I be punished?
b. I was allowed to use my HP after agreeing to clear the memory before the 
   exam (I archived everything to PC)
c. Shouldn't a distinction between 'programmable' and 'programmed' be made?

Hi,

I sent the brand new QED 1.09 public evaluation release to
hp48@seq.uncwil.edu, so I hope you'll soon find it in
comp.sources.hp48. A really nasty bug has been fixed that could
have caused system crashes.

This is an excerpt of QED.TXT:

1.08  01-09-92   Only a very small change has been made compared to
                  version 1.07: If you've got lots of libraries
                  installed, you won't see QED leave with an
                  insufficient memory error - QED now allocates
                  some memory to save the ROM-entry table for
                  this case.
                 NOTE: Only registered versions of QED are changed,
                  the evaluation version stays 1.07

1.09  21-12-91   Sorry to anyone who suffered data loss when running
                  QED 1.08 - there was a bug in it that caused
                  system crashes under some low-memory-conditions
                  and on ROM revisions < E.
                  This bug hasn't been in QED 1.07...
                  I spent a lot of hours on QED 1.08 just to
                  reproduce the bug, than another couple of hours
                  to fix it.
                  Now everything should definitely work fine... you
                  may load your 48sx with hundreds of libraries,
                  and even the PICT is not scrambled any longer -
                  only if your PICT is smaller than 131*64 pixel,
                  it will be resized to 131*64 and cleared.
                 The default QED.keys object is now much more complete
                  and similar to the original key-table, especially
                  the right-shift-ALPHA keys have been added...
                 The KEYED has been renamed to KED, put in its
                  own subdirectory and modified a little bit.
                  (see KED instructions)
                 The 6x6 font is now complete, as the 6x8 font has
                  been before. In the 5x6 font are still some
                  seldom used characters missing.


I believe this version to be _very_very_ stable, but I also know
nothing is perfect at all...

I hope you'll enjoy this version of QED even more than the versions
before, and take a look not only on the new executable, but also 
at the default fonts and the reworked key-table, both have been
improved.


Registered users can update from any former release of QED, if you've
got an email adress, just drop me a line, and I'll send you
your licensed executable uuencoded. If you don't have an email
adress, send me a SnailMail with the appropriate amount of US$
for postage.

cu, Lutz Vieweg

PS: In the past there has been sometimes trouble with the submissions
    to comp.sources.hp48. I'll post QED 1.09 to comp.sys.hp48

And from a Professor's point of view, there should be nothing wrong with
your using your calculator for this purpose.  I've had professors who use
the books _they_ originally used for learning something to teach from, and
they use different symbols than the book _we_ use.  Realizing that people
do use different names for variables out there in the "real world," you
ought to pick a set of symbols you're comfortable with and stick with them.
Professors trying to force you to use the set _they_ like would be
remarkably silly.  (beta=k, i=j, etc., etc.!)

My linear systems and signals class exams usually consisted of you _SHOWING
YOUR WORK_ in deriving some of the easier Laplace Transforms, and then
using the properties of Laplace Transforms to answer questions about system
responses.  Since really, actually doing the Laplace Transform is a math
question, and once you've demonstrated that you can set up the integral
properly, it becomes a mathematical operaiton that is no longer linked to
signals and systems in particular.

(I like exams set up in this style... "Given this problem in the field
we're studying, turn it into a problem in another field so that you can
find someone else to actually evaluate it." :-) )

Although your concept is valid, the implementation of it gets sticky
for one very good reason.  Suppose you're teaching a complex topic.
Suppose one of the brighter students programs an HP 48 to do it all
automatically, complete with input prompts, step-by-step output of all
your required "intermediate steps" so that the student can "show the
work"... and then that student beams the program to everybody else in
the class and shows them how to use it.  They pass the exam with full
marks, and learn absolutely nothing.

I personally avoid this by writing the programs myself, explaining to
the class as part of the lecture and homework exactly how the programs
work, and then including on the test some questions not only about the
math at hand and applications thereof but also about the HP 48 program
itself.  I require an understanding not only of the basic concepts but
also of their application to real-life problems and real-life tools.
One of my favorites is "This program gives bogus results with inputs
of thus-and-such; how wrong are they, and why?"
