Hello,
Today a rescued a load of clipper stuff. I've just finished taking everything
out of the car and it consists of the following items:
Interpro 125 + monitor
4x Intergraph 2000 (I already had one of thse myself); I opened one and they
seem to have C300 clipper processors.
2 other monitors
keyboards and mice
2 A3 tablets
lots and lots of cables
stack of documentation (looks complete to me)
and last a lot software. I've got boot floppies, cd's, Informix and
Microstation xx, all with licenses.
I'm now trying to get things running. I've booted the Interpro 125, but had no
succes with the workstations. Will these work with the same monitor as the
Interpro 125? The other monitors are still standing downstairs :(. I tried
connecting the 125 monitor to a workstation, but didn't get a picture. Or maybe
I should sort out the manuals first and look there...
I'm only planning to keep the Interpro 125 and one workstation, so if anyone
is interested in obtaining a machine/Clix, please mail me. I got these for
free, so you can have them for shipping cost only (from .nl).
greetings,
Michiel
ps. Another question, what kind of memory do these machines take? It looks like
standard 30-pins simms, Is this correct?

Also worth noting, a new beta version of OS-9 Level 1 (for the CoCo) was
recently released. It include bug fixes, and back-porting of some level 2
commands.

"Life. Don't talk to me about life." - Marvin, the android
A friend of mine just picked up a Nintendo Family computer at a garage sale but he didn't get the power supply. Does anyone know what voltage and polarity this needs? He said that it looks like this one <http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1372013871>. (The computer is the red and white piece on the left, the burgundy part on the right is a disk drive).

Hey, lets not bash the CoCo 2. It was meant only to be connected to a TV.
People used to sell composite conversion kits. But I haven't seen anything
recently. Except the rare modded CoCo 2 on eBay.
Best place to ask is on USENET: bit.listserve.coco. Someone usualy has
something tucked away in a drawer.

Quadra 360? Is that the not as talented version of the Quadra that can
skate a 720?

Congratulations! A fine box indeed.
I might be able to help ya; I scrapped a pile of Cromemco stuff and Dan
Cohoe's name is on most of what's left, but I believe there is most of a
spare Z-2 cabinet left over, including the front panel (the version without
floppy drive cutouts).
But an S-100 chassis (especially the Z-2) is only that; as far as disk
drives & OSs, that would all depend on what cards are in there.
FWIW, I do have copies of 11-(Z80), 20-(68000) and 30/31-(68010)
series Cromix, CDOS (their version of CP/M), and various utilities and
languages. Also some cards & lots of manuals, at least until Dan cleans
me out.
What kind of info do ya need?

Hi,
I am planning on purchasing a Cromemco Z-2 system shortly, it has some
special purpose Atari designed boards installed and was used within Atari to
develop Atari 2600 VCS games. However the unit is missing the front cover,
disk drive and OS software. If anyone can point me to a site(s) with good
information on the systems and anyone who may have spare parts to sell like
boards, keyboard and so forth, please let me know, thanks.
Curt

I did a little further disassembly and found a miniscule flourescent tube,
but it wasn't broken. I put everything back together, giving firming nudges
to all connections and tried it... the gods must be smiling upon me for,
behold, it works!
I've dodged the bullet ;) the laptop really belongs to my employer.
Regards,
Chris.

I've a pair of 40mb Rodime drives here (RLL'd out to 67mb) that have
been running since 1988 - almost non-stop (on one of the BBS machines).
One is a little noisy (always has been), but apart from that they are
extremely reliable - let's see they must be at least 7 or 8 years past
their "use by" date ? No dead sectors, no power up sticking - the only
drive older is a 20mb Seagate ST225 that has been in use (sporadically)
since oooohhh 86 or 87. Got plenty of spare ones though :-) Wonder
what a hundred or so ST225's would go for on eBay :-)
cheers,
Lance

The PMOS doesn't pull down vary hard. It is usually in the order
of a milliamp. It is hardly enough to cause problems
for a signal diode that are usually rated at 50 ma.
It might be open drain but even so, the pulldown is usually
small enough that, to interface to TTL ( that has an effective
pull up on it's input ), one has to add more pull down to get it
to work well. This is why the resistor. The diode is just to
limit the swing. The voltage is then across the resistor and
any small pull of the PMOS.
The pulldown of the PMOS is a constant current type so it can
be clamped without doing damage.

I was working for a rat-hole computer store when the Kaypro 10s debuted
- Kaypro made a deal with Lal Tandon to buy 10MB drives made (IIRC) in
Mother India - at any rate the 10s of that vintage had about an 80% DOA
rate.
You could (and I did, on numerous occasions) show up in the reception
area of Kaypro in San Diego lugging a 10, and someone would bring you out
a new one on a box, that had been burned-in... no questions asked, just
"Sorry for the inconveience, here's a new one under warranty."
They had a big tent set up in the parking lot complete with mobile
air conditioners to handle all the re-work. It was truly a nightmare.
These were from the batch where you could pay extra to have your unit
'personalized': it was supposed to be a mark of distinction that you had
an expensive portable computer with your name tastefully inlaid. What
happened in practice was the last guy on the production line took one of
those vibrating-carbide-stylus things and scrawled whatever was on the
invoice all over the back plate - never mind the paint or the
silk-screening.... it's funny, now...
AND - my 1988 Mac SE30 came with a CMS internal HD, complete with a nice
copy of nVir - courtesy of a disgruntled quality-control tech at CMS. It
would replicate itself at intervals and grab the speaker and say "Don't
Panic" in that early MacInTalk voice. Then at some point it would say
"Now Panic!" and trash your HD. Pretty tame as virii go today, back then
the store I bought it from had to shut down for two days while they
disinfected every machine and disk in the joint. Mine included. And I
just recently found the original invoice for that machine, which looks
down on me now from the shelf where it sits in snug reirement; it used to
run my music studio.
Cheers
John
