Hi All,
Looks like I did a huge mistake, when I was young I did not buy HP
calculator.
Now I have two of them, but none of them the old  what You guys mention .
I have one 48G, one 32S. I just wanted to know they are really that bad ?
Thanks,
PeterS

What??? HP's are the best calculators on the market. RPN rules.

That's what I always have believed... but a look at HP's website
shows that they now make only ONE RPN model!  Has market
demand really dropped down that far?
Sorry for the wanderings.

Hi,
Sorry, I do not want ot confuse anybody. It was a different discuss about
calculators and few poeple
mention and older HP ( I think it was HP 16 ) and they said that was the
last good HP calculator.
That is why I was worried . Actually I really satisfied with my ones ( both
of them RPN ) especially with the 48G.
First I purchased a CASIO color with graphics, almost the top of the line
and returned next day. After I both the 48G.
Cheers,
Peters

I have an HP48G and just love it.  I build my own cables too, the
connectors on the inside are 2mm which are kind of hard to find, but
Digi Key has them.  They are also kind of hard to work with.  I don't
know if it is illegal or not, but I build them and sell them at my
school.  I have also interfaced the 48g with a pic.  I built an A/D for
it.  It has kind of slow seeing as the data collection is real time, it
would faster if I did the data collection then did a serial dump to the
HP.  NOw I'm just rambling....I guess the point is I LOVE MY HP!!! If
that's any help to you.

Actually, they may only be actively producing one calculator at the
moment, but various sings say that they will be releasing a new one
sometime. hopefuly soon.

Hi!

Even with the lastest high end Casio or Texas calculators,
the HP48G and GX remain the most versatile and powerful
calculator on the market.

their qualities are not (only) based on the fact that
they use the RPN rules, but also because they have a
powerful processor (the Saturn) lots of memory, a
programming language between Pascal and LISP and the
possibility to program it in assembler. It's the only
calculator I know that can open cars locks and run
video games like a gameboy.....

I still prefer my Sharp EL9000.  It has a 15X4 character display.
Does graphing of functions, solves matricies, does the number
conversions, has two programming modes, stat data entry, and
26 user memories - each with it's own button. And it prints and
transfers data too.

Two of my co-workers have these super calculators that can do
just about anything, but it takes them 5 minutes to do the calcs
because there are just too many features!

The discussion was about "programmer's calculator" - calculator for
computer programmer, not about the "programmable calculator" :-)

HP48 is very good scientific calculator, but I am affraid that this
calculator lacks the programmer's features like rotate through carry,
unsigned - signed arithmetic etc.
For "scientific" purposes (mostly sin cos tan ln) I am using TI-92. Not
RPN, but good enough. But I would like to buy old HP-41CX if I will fond
some in good condition.

For what its worth, I have one too (many engineers probably have).

Without going and looking I think it includes
- a core memory or two (300 bytes in A4 size area)
- a one valve radio control transmitter (galloping ghost?),
- several rotary telephone exchange switches (electromechanical using
centralised motors and electrically operated clutches,
- Ye olde crystal set (adjustable crystal!)
- 6CW4 nuvistor (as found in MIG29s? :-))
- Calculator with core memory.
- Calculator memory using wire coil as memory.
- Originalish IBM PC (clone?) motherboard board with 16K RAM.
- Pre OC71 (OC640?) glass transistors.
- ZX81 (80?)

Much more, but mind grows dim. Must go and refresh memory.

What other interesting things are out there in museum boxes
Maybe someone should add a PIC or two to keep this not too OT.

Unfortunately, the only people that tend to appreciate these museum
boxes are other engineers, or students (the U has some display cases of
old stuff). So, I stopped collecting things and just threw them away.  I
still have a bunch of old motherboards and stuff, kept thinking that
someday they might be of good use, but with prices so low, it doesn't
make sense to even keep it around.  I keep things that might be
collector items by the masses....

Take a look at some of the games that people (mostly bored high school
students) developed for the TI-85 and TI-86.  BTW, I am partial to the
TI-86.  It maybe that I am just used to the TI way of doing things, but
it seems easier to use than the HP48.

Hi Andy and others,

I suspected that they might use power tubes such as magnetrons, but I never
knew that they used miniature tubes such as nuvistors. What is "wrt"
impulse radiation?

A comment was also made that with such tubes, a MIG-29 might still be able
to fight after a near nuclear miss, but an F-16 could  only fly. Actually,
that F-16 probably couldn't even fly if its electronics were so affected,
considering that it is fly-by-wire with an inherently unstable airframe.
Don't they shield the electronics from radiation? I suppose that it is not
very effective. Also, I would think that tubes would be somewhat
susceptible as well due to charge excess build up on the elements/
ionization of the gas inside (if it uses one).

I read an artcle years ago about hydraulic computers.  I think it was
showing how aircraft could use them as backup if the electronics was
detroyed in a nuclear blast.

There are nuclear hardened versions of IC's and transistors.

I believe the problem with semiconductors is that radiation impulse
flattens out the hump on the junction making the device a conductor
(resistor).

Of course, I can be entirely wrong about these things!

I think that no modern fighter is inherently stable enough for a safe
landing without assisted attitude control (i.e. at least rate gyro systems
and controls, or more). So even if it keeps flying it is not very useful
anymore.

The main problem is, people die slowly vs. electronics when the reason is
EMP or radiation. Also, scores of fighters would be totally useless if
caught on ground by a nearby nuke outside shelters, even if otherwise
undamaged. I don't think that the valve trick serves to protect them
mainly in the air.

Hydraulic 'computers' (more accurately automatons) have seen widespread
use in certain household implements, such as automatic washing machines,
and watering systems where they do an excellent job. Pneumatic automatons
are very ubiquitous in modern CNC and robotic plants.

The only serious problems are, speed and interfaceability. It's pretty
hard to make a hydraulic computer drive a CRT display, and it had better
operate at speeds below the speed of sound in its innards, which is a
fraction of the speed of light, but fast enough to move control surfaces
way faster and smoother than one can believe.

No hydraulic Pentiums are planned for the near future ;)

I also have this thing. I had a Spectrum 48K with rubber keys :-))
But the most valuable piece of my collection is two modems which I built
for ZX81 and ZX Spectrum.
First one is build around 4046 PLL chips, opamps and russian copy of 8251
300 Bd
Second unit is much more advanced, build around East Germany copy of Z80
SIO and Am7910 chip (pretty expensive chip, back in 1986. My friend brought
me this chip from former Western Germany). Modem has 1200 Bd and 300 Bd,
automatic pulse dialing via relay driven by DTR line.

Both units was built in 19983 - 1986 when the "modem" was forbidden word in
communist East Europe. Both units are working like a charm till today, with
ZX81 and Spectrum, with proprietary assembler programs. The Spectrum
program can also transfer files via X-modem protocol.
