	I've been playing with the Proffesional Devolopment Link demo for
a while now, and have come to like it, I'd like to get the real thing, but
the cost is a little more then I can afford, hence I've started to save my
pennies, but I also noticed that the kit includes a disk, cable and 
programmers reference, but I already own these three things (legit cable
too, from the Back to School promo) and was wondering if anyone knows if
I can get a price break? The README file with the PDLDEMO program says
I can get it for $30.00 US, but it doesn't mention if that applies to the
promotional back to school kit, plus it says US only and I live in
Canada. Further I still will have an extra Programmers Reference, does
anyone know if I can get a bigger break still? I can kinda guess the
answers to the questions, but I'm hoping someone will surprise me.

	2nd. Part:
	The PDLDEMO has the limitation that it can't save files, but I
made a program up that when copied into the PDL directory will allow
you to save your current application. It doesn't require any modification
of any of HP's PDL files, and I've been using it succesfully for some
time now. My question is, is this type of thing a violation of copyright
law? It certainly violates the spirit in which the IPLDEMO was released,
but how about legally. I'm wondering because I'd like to upload it to the
group and to seq.uncwil.edu if there's general agreement that it's legal
and if most people seem in favour of it's upload. Anyone?

P.S. Flame me if you want for making such a program, but I feel no guilt
     as I will buy the real thing as soon as I can afford, and I feel that
     basically makes it all right, at least for me it does.

Howdy,
  I recall when the HP48sx was first released back in 1990 that many
  people noted that it did not have a very flexible alarm system. I don't
  recall the particular models that people mentioned but the bottom line
  seemed to be that the 48sx's repeating alarm are very basic.

  Well, I'm working on writing a complete repeating-alarm system for the
  48sx and would like some ideas of what to incorporate. (This started out
  as a project to turn my 48sx into a fancy alarm clock. With a few
  extensions here and there, I've gotten quite a bit of code.) Before
  proceeding any farther, I would like to see what HP has previously done.

  Things that I have already incorporated:
    o weekday/weekend detection
    o public (Canadian) holiday detection

  I think that many people would like things like "2nd Thursday of every
  other month"-type alarms. What else?

  I would also like to find out how alarms worked in previous HP models.
  What syntax was used to specify the repeating intervals?

George

	   Of course, keeping in mind that there is also the HP-48S as well. 
   I'm not sure about down in the U.S. but in Canada our minimum wage is
   ~$6CAN, that has to be taken into account as well (University co-op student
   make more than that usually, often quite a bit).  Food for thought.

I think minimum wage in the US is lower than this in most states
(we're a less developed nation than Canada).  On the other hand, "take
home pay" means after taxes.

The real pain is that if you are a student with a $4/hr (take home pay)
job, you are probably working as many hours as you possibly can and
barely meeting your expenses.  Thus, $275 doesn't represent "70 hours
of work", but rather, several MONTHS of your discretionary income.
(I dropped out of school because of this phenomenon, and worked full
time until I'd saved up enough to go back and finish).

Sorry, I don't consider a Powerbook 100 a real computer for engineering use
(since you have been talking about running Mathematica).  I can get a new
Powerbook locally for $500, and try looking at Educalc...they sell the 48S

Coupla years ago I wrote a triangle solver just for fun that had a
very simple user interface, led internally to only a handful of cases
(was it 9?) and appeared to run instantaneously.

Here's the idea; feel free to implement it if you wish.  The six
softkeys are SIDE A, ANGLE A, SIDE B, ANGLE B, SIDE C, ANGLE C.  Type
a number, press a softkey, and it turns black-on-white to represent
that it's got a value.  Press 0 and a softkey to "turn it off".  As
soon as the third value is entered, the program automatically
calculates the other three and puts them (tagged) on the stack and
sets up for another go.  It wasn't a very big loop.

I remember now; the cases called subroutines that contained all the
necessary trig, like the law of cosines, in its four basic forms, and
the law of sines, in its two basic forms.  Local variables obviate the
need for "duplicates" like these three:

         a = SQRT(b^2 + c^2 - 2*b*c*COS(A))                     (1)
         b = SQRT(a^2 + c^2 - 2*a*c*COS(B))                     (2)
         c = SQRT(a^2 + b^2 - 2*a*b*COS(C))                     (3)

These are "formally" identical, so they can be coded just once, using
local variables, and then called from anyplace and passed any values,
even if the variable names don't agree; only the stack position would
be important, not the names.  Of course, this subroutine would be
called SAS, and take two sides and their included angle as input, and
yield the third side as the output, e.g.

         b c A SAS 'a' STO          for (1) above
         a c B SAS 'b' STO          for (2) above
         a b C SAS 'c' STO          for (3) above

The SAS routine could be as simple as this:

<< -> a b C 'SQRT(a^2+b^2-2*a*b*COS(C))' >>

Good grief, I'm doing your homework for you.  ;-)  -jkh-

If you are able to hook your HP 48 up to another computer or to a
printer, there is a nice pretty-printer that is automatically
invoked when you print an HP 48 program object.  It is not much
different from the pretty-printer used when you edit a program
object, except that it doesn't wrap lines at only 22 columns when
sending output to the serial port.

I have set an alarm that does an automatic backup.  If I goof and

go to the backup to restore.

To backup:
  setup an alarm, some infrequent time like 3am, with a repeat of one day

The really interesting thing is that it appears that you can have alarms
go off while changing batteries, and the '48 doesn't turn on or lose
memory, but runs the alarms only once it has enough power to do so.

(At least, I haven't been able to reproduce what happened the first time
I changed batteries with an alarm going off and I had to give it a
hardware reset to come back to me, with memory unperturbed.  I concluded
that I must have done something else wrong. :-)

The longer I've had HP calcs, the '48 in particular, the more I realize
that the higher price for an HP calculator turns out to be a bargain at
their quality level.

The only class in which I have ever been prohibited to use my 48SX was
a freshman-level half-credit chemistry class (which I took recently as
a junior). The major part of the final test would involve numerical
approximations and something to do with matrices.

Heh Heh.. revenge time!

I used my "non-programmable"  old 15-C (if it doesn't have an alpha
keyboard, it's not programmable), and as a protest I spent about 6
hours writing two 'do-it-all' programs. I think I even developed an
entirely original algorithm for one of the methods. Of course, I could
have just studied the material for one hour and would have done just as
well in the test.

What some professors fail to understand is that a student with a good
calculator (i.e. an HP) is not in advantage unless:  1. He knows the
material thoroughly; AND 2. He knows the calculator thoroughly and has
the extra time  to program it.

Fortunately, here, all the EE professors can see that!

1) Is there a portable (or, barring that, Atari ST compatible) sys-RPL compiler
 like HP's RPLCOMP for the PC's?

2) Has RPL ever been implemented on a system other than an HP calc? I think 
 it's a pretty neat language, it might be interesting to program with it on
 a more powerful system.
