Does anyone have any info on the I/O port on the back of the HP9100
desktop calculator? I believe that HP once produced a manual telling you
how to link up homebrew/custom peripherals, but I don't have it, alas
What I really need is a pinout, brief signal descriptions or timings, etc.
I want to be able to output a few on/off signals (I don't care if they're
binary or BCD encoded).

If this ends up being a duplicate, my apologies. The first one was sent
while I may not have been subscribed under my new address.
In any case... yes, a new address. I had to ditch the old one due to
spamming. Please note the new one: kyrrin2(a)wizards.net.
Caveat emptor!

Sounds like a National semi development system. The NSC800 is a cmos z80
that is 8085 bus compatable if I remember right. Generally speaking
development systems tend to be scarce as they are not hight volume.

Hi, folks,
Well, it had to happen eventually I guess. I've had to change my address
due to spamming of the old one. Please note that my new address will be
kyrrin2(a)wizards.net.

Hi
I found a scrap place today that ahd a few computers - got on good terms
and now they are going to ring me whenever they pick one up. :) Apparantly
they just scrapped an old Xerox box, but no details, and they get the
occasional Altair and stuff. Anyway, they had little on hand that
interested me (I already had their Amstrads, and the Commodore 128D's had
no monitor or keyboards, so I thought I would think about them), but I did
pick up something - I just don't know what it is. It's about the size of a
original PC/XT, but the case is blue - with a blue clear panel on the
front. Has two com ports and a vdu port, and two 8" drives. I opened her
up, and she has a rack with everything plugging in at teh back, inc lots of
controllers. There was a NSC800 cpu module, and when I removed it, sure
enough, there was a NSC800 N-1 cpu. No idea what that is though. Heaps of
switches, leds and stuff behind the front panel, too.
Anyway, this is somewhat outside my normal collecting range, and isn't
probably of much interest, but at a couple of dollars I thought it might be
worth looking into it. Can anyone tell me what it is, or anything about
it?
Thanks heaps,
Adam.
Hello, again...
Well, the Altair scans got here today, and I must say that the quality is
excellent. There's stuff for the 8800b, the 8800, some add-in boards, and the
"computer-notes" pamphlets. All told, with the schematics, there's about 90mb
of info. Based on a quick count, there's probably 750-1000 pages of info. The
files are in Adobe Acrobat PDF format.
As soon Bill can reach his computer again, I'll Fedex them to him to post on
the ftp site.

Last weekend at a garage sale, a guy wanted to sell me three things (kiddie
cars) for a quarter. I gave him $.50.

Yeesh, if you run into any, I'll trade you for them! I have several
friends looking for them.
I know of only two collectors besides myself who have 5100's. In
contrast, there are about 15 Altairs represented on this mailing list.
I do know of an Apple I that's for sale... anybody got $10,000 burning a
hole in their pocket? Yeesh.

Maybe we can help someone sell an old system in the future. I'm just now
fooling around with an internet auction. We hope to do another in the future.
