Unfortunately, the chances are that it will _not_ work.

My experience is this: last summer, we went to the zoo.  I had my
HP95LX in a carry bag along with a water bottle.  Someone forgot to
close the bottle an some water leaked.  The 95 was on end in the bag,
and the end with the power connector and serial port connector was
down.  It got wet.  I estimate that less than 0.3 cm^3 of water was
"wicked" into the 95's innards.

Now, if the 95 had been off, I could have dried it out (as described)
and I expect that it would have worked fine.

HOWEVER: THESE DEVICES ARE NOT OFF!  THEY ARE DRAWING CURRENT TO
MAINTAIN THE CONTINUOUS MEMORY!  I would have had to remove _all_
batteries _immediately_.  I (and chances are you) did not.

Actually, the inside looked neat.  There was this gray fuzz that had
grown among all the chip leads...

The 95 was totalled.  $325 to repair (ouch!).  I now have two carry
cases for it (one at home, one at work) (I really like the Sparcom
case.)

IEEE Spectrum had an article on how water affects electronics.  I
think it was sometime in the spring of 92.

One advantage of the 48 is that its ROM routines would be the 
C library/kernal, so code needn't be that big.

if the student is guilty of cheating, then you have to prove that.
Even if the matter doesn't wind up in court, shouldnt the same standard of
justice and fairness apply to the university's conduct against the student?

Forcing a student to retake an exam, when the professor or university
can not otherwise *prove* the student's guilt, is arbitrary and unjust.
It is not up to the defendant to prove his innocence! Perhaps you need
to re-think some things here; I think you are losing sight of
some fundamentals, in the process of solving a problem you face as a teacher.

You need a terminal program that speaks Kermit, or the Kermit file transfer

Hmm?  Generally alarms will cause the calculator to turn itself back on and

Yes, try the HP-48 FTP site seq.uncwil.edu.  If you decide to look at

I've found the program IR_SAMP (available at seq.uncwil.edu) to be very
successful in recording IR remote signals.  With it i can now completely
control my VCR.  I even made my user keyboard like a remode control with

BTW use redundancy fighter because it compressess the Remode data strings

           PIN CONNECTIONS FOR HP48 TO MACINTOSH CABLE

               By Darren Cokin (cokin@scf.usc.edu)


There are 1680 possible combinations of pin connections.  I found a
description of the HP pins in the comp.sys.hp48 FAQ, and a partial
description of the mac pins in the CapNet document by Nate Hawthorn.  I
was thus able to narrow down the combinations to a dozen or so.  Testing
one at a time gave me this combination, which works well.  You're on
your own finding connectors to fit the jacks, but at least now you know
which wires to solder together.  Just match the numbers.


Looking at back of HP48

    ---------
   | 1 2 3 4 |
    \_______/


Looking at back of Mac serial port (modem/printer port).
This type of connector is called a "9-pin Mini-DIN" (the 9th
pin is the outer ring).  X marks pins that are not used.

     -------
   (         )
 (  X   1   X  )
(               )
(  2     4   3  )
 (             )
  (   X   X   )
    --------

This has worked well for me, but I make to guarantees.  Use at your own
risk.  I take no responsibility if you damage either your mac or your
HP48.  Feel free to distribute this document, I place it in the public
domain.

No need to think about it. The claim was made that microwaves are tuned to heat
-water-. This is not true. This was the point which I was attempting to address,

You might look around for an isopropyl alcohol that is a high percentage
of alcohol.  In other words, many isopropyl alcohols that you get in the

Don't worry too much about that. You can use all the relevant tools on any
computer for that exists a C-Compiler. You can connect the HP48 to every device
with a RS232. Furthermore, you can emulate a PC on nearly every computer, but
you can emulate nearly no computer on a PC.

Blablabla. If there is *anything* needed in 5 years in Windows No Technology,
everyone will be sad it runs on machines that only allows [insert incredibly
good feature like 4 Terabyte RAM, 256 GB Harddisk] and is as cheap as those PCs
are.

But that's another story, we shouldn't talk about other themes than the HP48 on
this board. As far as I remember, I never said which computer I use in this
group, and it just doesn't matter.

This is almost right. Actually, the location of the reset switch has
changed at least once. When I had my version A, it was under the upper left
foot (with the lcd facing down). When I upgraded to a version E, the reset
switch was under the upper right foot with the calculator in the same 
orientation. Its better not to go by what side people tell you, its better
to just pop off the feet and see which hole has the 'R' beside it.

I just got my HP48sx last week, and made a serial cable.  If anyone wants
the HP to Mac pin connections, I can post.

There is a lot of software available on seq.uncwil.edu and hpcvbbs.cv.hp.com
and way to much for me to wade through.  I'd like suggestions of stuff you
all think is good or essential.

I have already gotten asc, schip, Joust and Blinky.

I'm mostly interested in games, but would also like a good program for turning
the calc into a universal remote, vector analysis, physics (kinematics,
electricity, magnetism), calculus, and anything at all to do with Mechanical
Engineering (my major).

I'd like a way of working with vectors that have variables as components.

	Sometimes when I transfer from PC --> HP 48SX it takes several tries.
I type send at the KERMIT prompt and recv on the 48 menu and it continues to
retry until I abort and try again.  Eventually there is a connection and the 
transfer is flawless.
	Does this happen to everyone or just me?

I just started a digital logic class and we are doing number systems and 
conversion.  The hp48 works great when you have whole numbers but if you
add a decimal IT CAN'T HANDLE IT!!   WHY?  I can do it on a sheet of paper
why can't the HP do it?  If the ROM can't handle it, is there some software
out there that can do it?  I was stunned that the HP couldn't do it....

It is simple math to do the conversions....

Example:
--------
To see what I mean try to convert 757.25 (base 10) to octal and binary.

The program you want to put in takes alot of memory.  You will
probably have to check you memory and erase stuff to fit it
Off hand I can't remember how much K it takes, but it took alot
I got it to work just fine, but since I don't have a ram card
yet I did not think it was very good utilization of my limited
memory.  If this isn't your problem, E-mail me.

Cheers, eh,
