	Does anyone know the pinouts on the HP48SX's serial link connector?
Does it run in standard RS-232 levels?  How much is the HP adapter?

					Thanks.

Do you mean compact enough that your professor will not be able to tell

Try right-shift (the blue one) followed by the decimal point (if you look at the left-shift character of the decimal point, you will notice that it looks like the symbol on many computer enter keys, i.e. an arrow going down then left).

Date: Sat, 19 Dec 1992 18:24:00 GMT

  I'm looking for some feedback on the attitude different universities have
to using calculators like the HP48 in examiniations.
  Over the past 2 years then number of HP's at Concordia University has 
probably tripled.  The problem is the teachers are really unaware of their
capabilities and view them as merely an expensive electronic crib sheet.  
Due to this there is much opposition from the professors to allow students
to use "programmable" calculators.
  I'm interested in hearing about experiences that other students have had 
relating to this.  Do other universities allow them, encourage their use or
maybe (god forbid) actually teach students how to use these tools?

Ok, here's another in the rapidly lengthening list of Things The HP48
Should Do But Can't (Yet) ...

Why not have a ROM card with a dictionary or spelling checker
(or both) on it?  I was sitting here just the other day, considering
buying one of those hand-held spell-checkers, when I thought "Geeze-
I've got this hand-held computer, why don't I use it for that task??"

Anyway, just another thought...  I clearly don't have the resources
to create one of these, but may someone reading this does.

Or, try Elek-Tek (1-800-395-1000).  They sell the Owners Manual (ver. 1.2)

Hi I made the remotecontrol program that you are looking for.
Look at seq.uncwil.edu under hp48/comp.sources.hp48/volume05
(I think it is volume05). There you will find remote_bg.

If you can't get it mail me, and I will mail it to you.
But at the moment I am very busy, so it can take a while.
I am trying to improve the progams so that the hp48 can learn new remotes
without having to use an oscilloscope to see the waveform.

Yes.
Try EduCalc (1-800-677-7001 or 714-582-2637, Laguna Niguel, CA, USA) and
ask for a catalog to be sent immediately. If you just put in a routine
request, they'll wait and send it out in the next quarterly bulk mailing.
If you ask really nice, they'll send it out immediately.

Among the gems to be found are Jim Donnelly's "HP 48 Handbook". Stock # 2246,
$19.95. This is *the* book to have. There's dozens of others, too. 

Feel free to call if you have questions.

	You need a null modem adapter to swap the send/receive lines,
that should get you going, but I recommend 'mlterm' over nrts myself,
mlterm is the only one I've found yet that's fast enough to be reasoanble
to use, but it doesn't emulate a VT52/100/102/etc like some other do.
I does process CRLF's correctly though. Have fun! BTW Be sure to get
the handshaking set right or the HP will miss a lot of characters. :-)

HP 48: Same method as simultaneous real equations:

       [ constants ]  [[ coefficients ]]  /  -->  [ solutions ]

HP 42: If MATA, MATB and MATX are not complex matrices, recall each to
       the stack, press ENTER, COMPLEX to make it complex, and re-STO.
       Then use the SIMQ function as usual, entering complex numbers
       for each matrix element.  The MATX solutions will be complex.

transmitting without registered equipment a Federal Crime? If not, What 
frequencies would be able to transmit and at what power level? I was thinking 
that we might be able to use those "TOY" frequencies, I.E. Radio Cars in the 
49MHz range. With all the "Dime size" FM transmitters out there, It 'ought to
be easy to make the "cheater" or "networker" small enough... 8-)... SMT 
{Surface Mount Technology} is great, isn't it 8-)!

                                              sampling programs v1.0

I would go ahead and get the ZIP files and search through them.  They have
plenty of programs that will keep you entertained.

Instead of giving only one guess for x, try giving it 2 or 3.
For example, put { 0 4 } on the stack and press the x menu key (in
the solvr menu).  Then solve for x.  It should give you the correct
answer of x: 2.64454252521 .  Or you can put { 2 0 4 } on the stack
and do the same.  The first method involves 2 guesses: the calculator
tries to find a root between the two guesses.  The 2nd method is
similar, but the first number in the list is a "best-guess" at the root
and the other two are the same as in the first method.

All this is in my manual on page 17-32 "How the Root-Finder Uses Initial
Guesses".  (The new all-in-one-book manual, that is)

By the way, the equation you have is strange... { 2 0 6.28 } gives
a sign reversal at 5.4428....
