Hi Doug,
I also bid on it but I decided to let you have it since I have several of
them already.

It uses HPL. HP's version of APL and BASIC crossed. Assign variables
like this "A <- 2" "B <- 2*A" etc.

There's at least three vesions, the A, the B and a T. The latter ones
had most of the optional ROMs built in. BTW I just bought another one, it
has a big warning label on it not to use any plug in ROMs other than the
Matrix and String (I think). It says that the others are already built in
and if you add a plug-in one that you may damage the calculator. I have
lots of docs for these and 6 other 9825s but this is the first time that
I've seen that warning.
There are also two very different keybaords used on them. The 9825 at
the bottom of your picture has the full travel keyboard. They're more
desireable.

Yeap! If it's only stuck you can usually pull them up and fix them.

Yes, HP did except they used a CRT. The HP 9826 replaced the 9825. The
9826 was shaped like an oversized Apple computer and had an integrated
keyboard, 5" monitor and 5 1/4" disk drive. You can see one on my webpage
at "http://www.intellistar.net/~rigdonj/hp9000.htm". The 9826 used a 68000
CPU and could run HPL, BASIC or Pascal. All of the languages were USUALLY
stored on disks and loaded from there but you could get the languages on
plug-in ROM cards. You could have any or all languages on the same drive
and/or in ROM on the same computer and you could select the one that you
wanted the computer to load. I have a drive with all three languages on it
and BASIC in ROM on one computer.
The 9826 was also called a 9000 226 model and was part of the HP 9000
series 200 computer family that included the 9836 (aka 9000/236), 9836C,
9816 (aka 9000/216), 9000/220 and 9000/217. Even though the 9826 was
designated as the replacement for the 9825 all the computers in that family
are generaly compatible. The primary differences were the number of
expansion slots, integrated vs. modular construction, overall size, number
of built in drives and wheather they had monochrome or color displays. I
have pictures on several of them on my website.

I took a gander at this page; is the mindset related to the MAD
computer? If so, then I have a Floppydrive/powersupply "upper half",
if you want it.

Finally acquired a MindSet pc this weekend, way cool. So now I'm looking for
anyone who has _anything_ for this unit (docs, specific software, carts,
anything). Any useful links would be handy too.

Hi guys & gals!
Uhh, lets not confuse .308in bullet size with bullet caliber.
The .308 Winchester cartridge was introduced in 1952 and adpoted in 1954 by
the U.S. military. It was designed with a reduced overall weight(a little
shorter).
The idea was that a G.I. could carry more ammo into combat! The correct
military designation for this cartridge was 7.62x51mm NATO.
BTW, I believe it's "aught" with an A!
Sorry, computers are not my only hobby.

The point is that it's possible to just "figure it out" by looking.
If you don't know what a cam is for, by process of elimination, it's
possible to eventually understand. On the other hand, if you're
staring at a board of custom chips, you'll never figure it out without
a computer to read the code in them.

If I remember right, those were the 1st computer manuals I ever got my hands on as a kid,
it was incredible stuff and caught my interest. Might even still have a few in Mom's attic.

Most of the computers were very hardy things and rarely broke down. When
they did, these highly trained technicians would be called in to do the
repairs, using all sorts of special tools (like really thin wrenches and
other "not-at-Home-Depot" type things.

:-) Someone has mentioned Jacquard, I think. He didn't invent punched
cards, afaik, he got the idea from a Brit. I'll try and find out more,
but I don't think either was a computer. The Jacquard loom doesn't run
a program - it transfers data from cards to fabric. Full stop.
I'd give the honours of 1st computer to the Zuse Z1 - a relay machine
between the Wars, I think. But some mechanical calculators at that date
were quite sophisticated. Comments, anyone??

They may have done, but the Manchester SSEM (Small Scale Experimental
Machine) was the first computer to STORE ITS PROGRAM IN MAIN MEMORY,
i.e. answer 4.
Again, Konrad Zuse's pre-war relay computers were digital. Go and watch
them running the Z4 in Munich...

Heh. I spent a couple of evenings trying to figure these things out
(have two, an A and a B) with mixed results. HPL is definitely case
sensitive.
The little dinky manual that fits under the printer cover is not enough
documentation to learn how to program it. That is all the docs I have
though.

In spite of what the hpmuseum.org web pages say, there are at least
two 9825Bs out there with the calculator-style keyboard. Mine's like
that too. I'm not sure whether it's a 9825A->B field upgrade or what.

I doubt it...those little dot-matrix LEDs were expensive compared to a
CRT.

Well all I have are the basic Alphatronic PC units (three of these I
think, although I seem to remember that the keyboard status on two of
them is far from perfect - these things used to be really abused when
used as terminals), one original shipping carton, two manuals, and
that's it.
Oh, did these things come with monitors at all? Most of the ones we had
at university had 12" mono screens hooked up to them, but I don't know
if they were original or not (I have a couple of these - similar shape
to DEC VT320 terminals).
The manuals I have (IIRC) both mention that the systems can be expanded
to run CP/M, but no mention of how or what was needed; there's no
pin-outs of the expansion port, cartridge slots or anything.
>
>> Owning a Alphatronic PC and 2 Alphatronics
hmm, so what's the difference between the two? Mine are all badged
"Alphatronic PC", but I checked with the university staff before I left
and they never had any floppy / hard drive systems with them...
(This is where I really hate not having my collection around at home,
it's been so long since I've powered one of these things up I can't even
remember what CPU they had. I vaguely recall that they had a lot of
fairly non-standard chips inside though; the CPU may have been a
rebadged part of some description)

My comment was that apple format is not unlike hardsector in that it's
not readable with most softsectored controllers. For all intents it
was not unlike the usually vendor unique hard sector formats.
Also DBASEII ran well on apples with floppies. The only penelty of
reading an entire track was memory space. The payback was speed as
there was an implied track level caching.
