I am looking for a cheap, simple (non-programmable) RPN calculator.
Something like a TI-30, but in an RPN version. Does such a thing
exist?

I am saddened by the fact that even HP seems to have lost faith
in RPN... none of their entry-level calculators use it anymore.

Are there non-HP RPN calculators out there?

All RPN calculators I know of are programmable.

When did RPN become entry-level, calculator-wise? The most entry-ish HP
I can think of is the 32, which is RPN, but also programmable. Not
exactly entry-level, but it served me well in 9th/10th grade (the 32S,
not S II, at the time).

If you happen to have a palm pilot or the like, there are RPN
calculators (also programmable) available on the public domain.

If you meant "HP" intead of the first "RPN", take a look at the HP 6 on
their Web site: http://www.hp.com/calculators/scientific/6ssol_info.html

Nice toys, but nothing can replace a real keyboard for extended use.

Not that I know of. It's looking more and more that HP is giving up
RPN. Their current line only has _ONE_ non-graphing RPN calculator, the
HP 32SII. I have one, and it certainly is an excellent calculator, but
it certainly was a lot of money ($45, I think).

If you look at the new HP-49, it looks even worse. Where's the big
"enter" key? Gone. Oh, there's a small enter key, tucked away in the
corner, but it's obviously not designed around the RPN user.

<sigh>

My advice: start stocking up on old HP calculators! I also have an HP 15C,
which is my absolute favorite. It's the same form factor as th HP 12C
business calculator, which I find super convenient to use.

I meant "RPN".

I agree re keyboard. The Palm has some nice things available for it,
though, including a fairly good spreadsheet (it helped solve a database
problem this morning), and realtively well integrated PDA apps. What
would be nice would be a mini-SQL for the 49... ;)

I haven't played with exal since (a few years ago) -- do the
calculations still propagate step-wise, or is it at the desktop level
now (all calcs update fully, no intermediates)?

I have a PalmIIIx and run RPN2.56 on it. It is a great, programable, RPN
calc. And the registration fee was not bad US$15.

That's what I got on a regular Palm3; haven't done any scripts yet.

The HP has one very simple, very significant advantage over the Palm --
you can program on the platform itself. If the Palm3 had a better means
of writing programs w/o requiring runtimes than code-warrior, I'd be
much happier.

Makes me wonder why they haven't bothered with C, which among other
things is very readily available, with quite a few very tasty math
packages available. I specifically chose not to take Fortran, and
substituted C instead, when I got my degree.

What about Java (the *real* Java, I mean)? I gather the Palm Pilot was the hit
of Java One. And I heard Bill Joy say that one of the earliest requirements to
be established for the next version of the language was greatly improved
features for numerical, scientific and technical programming - apparently many

scientists and engineers have been telling Sun that they would like to get away
from FORTRAN and like the look of Java but not the number-crunching
performance.

When I bought my last handheld, it was a tossup between a 48GX and a Palm III.
The 48GX won, but only because Java was not available for the Palm. Today, it
would be no contest. . .

Best,

I really wonder how much of a difference the smaller ENTER key will make.
We shall see. The lower right corner is hard to miss.

If I had Bill Gates' money, I would start a company that would make
new, improved versions of all the nice geeky things that disappeared
or are becoming harder to find:

- A solar 32SII in a 15C-like case (I share your taste in calculators).
- A *really* programmable remote control, like Woz's CORE.
- An avatar of the HP 200LX with a 486SLC inside, running Linux.
- A projection Vectrex with laser beams.
- A computer keyboard with the exact feel of a Selectric.
- A compact, white LED flashlight... oops, those already exist
(www.photonlight.com).
- An electric fan with metal blades, quiet and powerful.
- A Canon CAT, if it is as sanely great as I think it is.
- That cool Fisher Price toy camera that recorded on audio tapes.
- A QUIET refrigerator. Why are they all so noisy nowadays?

I'm sure the denizens of these newsgroups can think of many things
to add to the list...

Hmmm. This one ought to be easily doable with off-the-shelf parts.
Could be a big hit at conventions and whatnot. Imagine playing
asteroids on a 100 foot screen (i.e. a convenient building).

Might just look into this one...

Asteroids might be more suitable (and well-received) in a lasarium. The
sound system would also be much better, and they already have the lasers
setup (in color, even).

How about the 8-bit Atari "Star Raiders" or the old Star Wars game?
Warping with a wrap-around screen has its possibilities

Funny -- twelve years ago, some friends an I where into playing Astroids,
we had recycled some old boards and came up w/ at least one configuration
that worked pretty well (and still does). We came up w/ exactly the same
idea, playing it usen the wall of the house over the street as projection
area. We got a ruby laser set up as the projection heart (laser diods where
sort of uncommon that days :), but finally wheren't able to set up a high
speed X/Y mirror configuration -- there where a unit on the market that would
have worked, but for ~$10000... Maybe I should dig up the stuff again.
