The IR transmitter in the HP 48 can transmit at least 6 feet, at
least for the purposes of triggering a remote or printing on the
IR printer.  It's the receiver that's hobbled.  A repeater might
help the receiver.

I have had the same problem (only once) with a relatively new HP48-E (I had to
buy it to replace the one that was stolen :( ).  I got the calc about four     
weeks ago, and had to reset it because someone (jerk) took out my memory
card.  Anyway, I resetted it and said yes to the memory clear message, and 
waited almost an HOUR before trying to do ON-C.  That didn't work, so I tried
ON-A-F again, which didn't work.  So, I tried the reset in the back of the 
calculator, and that didn't work.  I took out the batteries, and the display 
sort of faded away slowly.  Really strange.  The when I put them back in, 
the display had an hourglass and a single horizontal line somewhere in the 
middle of the screen.  I finally took out the batteries for about a minute,
and then it was OK.  Luckily I had recently backed up the RAM so I didn't lose
much, but it was distressing.  I would be most appreciative to hear if anyone
else has had such a problem...

Thanks,
Matt Paschke

This debate shouldn't really take place on this board, but since it
started here....

I'm sure you've all heard that it's the amps that kill you, not the volts.
That's the truth.  It takes as little as .1 Amps, regardless of voltage. 
The debate about the resistance of your body making the current or voltage
dependent really doesn't matter.  There are such things as current
sources, in which case the voltage is dependent.  There are such things as
voltage sources, in which case the current is dependent.  The only
question is whether a lightning bolt is a current source or a voltage
source.  I'm not sure.  It would seem that the potential between the cloud
and the ground would be a voltage source, but the bolt itself might be a
current source (consider that a person struck by lightning may not be the
primary target - similar to grabbing any conductor with current flowing in
it).

I don't want the above to make me sound like I think I'm an expert - I'm not. 
It's just my opinion.

Gads. As a former EM3 in the Navy (Electrician) they taught us the minumum
was 100 ma. As for voltage, thats simply ohms law. 120 volts can kill you
if you are wet. When you are wet you have lower resistance. 120 volts
might not kill you if you are dry. Fall across 100,000 volts and you are
dead, wet or dry. It also depends on where you take the shock. I took
15,000 in thru my elbow and out my hand while working on a TV. If it had
been in my right elbow and out my left hand for any length if time
I think Id be dead. Your heart cant take much current at all.
The reason people survive lightning strikes is because the duration of
the pulse is so short. Current first flows over the outside of the conductor
before moving in towards the innards of the conductor. 

I dont want it to sound like I know all this stuff, on the contrary Im
just repeating that which has sounded most plausible to me.

Obligatory post:
 
 Can anybody recommend a good book on assembly programming on the 48?

This is just a rumor.  I have no idea if 2 students actually did this or not,
but HP48 calculators are allowed in tests at BYU.  In fact, Dr. Garner, a
math proffessor, uses an HP48 overhead in classes, and gives code to his
students for various math functions.  He heavily encourages the use of
HP48 and HP28 calculators to enhance your learning.

The testing center does have some TI calculators available, so if some
prof doesn't allow HP's, then the student can get a TI for the test, however,
this is completely up to the prof.  There has been no blanket rule for
the entire campus (or even one entire dept. that I know of) to ban HP48
calculators.

If I ever hear such a rumor here on campus about 2 students that successfully
hobbled the HP48 receiver, then I will certainally tell it here.

Well, I guess the question still exists as to whether it can be done.

To quote from the UWM Gopher
  
  "A list of microlabs and hours, along with all the rest of the campus
  facilities can be obtained in either the EMS E380 or Bolton 230 consulting
  sites.
  
  Csd maintains a beautiful public access micro lab in the Golda Meir Library.
  The lab is located on the second floor of the east wing, is for use by
  faculty, staff, and students. It features IBM PS/2 and Macintosh systems,
  and a multitude of software.
  
  Csd also manages several limited access microcomputer labs on behalf of
  the campus for specific divisions."

Take a Mac-formatted disk over there and get both Kermit & UnStuffit
(this process is called "bootstrapping.") Once you have Kermit on the
Mac, you can transfer, via Kermit, files of the kind you mentioned,
side-stepping the Apple File Exchange which, having no reason to
believe that UNSTUFFI.T15 is "really" a Mac executable, dumps the
entire file into the data-fork and, unlike some other brain-dead
systems, will not allow you to execute random junk.

An aside on the use of a Mac for '48 programming: There are a number
of Mac features which make it my personal favorite for user-language
programming. These include the HP48 Fonts, which make programs
transferred in Translate-mode-0 look exactly as they do on the '48
(and print out nicely as well) and can be used in almost any editor.
A second feature is graphics, including the Grober. Making QuickTime
movies from '48 output is nearly trivial, as is digitizing and
transferring images to the '48.  A third consideration is M.T.B.F. (in
a software sense.) I maintain for myself both a 486 PC and a Mac IIx
and I easily spend 5x more time figuring out new and mollifying
exciting new IRQ / HIMEM / EMS / Port / driver / etc. etc. etc.
conflicts on the PC than "INIT" (or any other) conflicts on the Mac.
If you take into account your per-hour charge for your own time, Macs
are _far_ cheaper.
