I just got hardcopy catalong this week and also checked on line. They have

The 8080A is the same thing and the 6800 also came in a B part (different
speed).

Today I picked up a KIM-1 with Commodore/MOS label for free they had it in
the trash at the yard. No power supply was with it and they sold these for
169.99 with power supply. Anyone have information or know were I can get a
power supply for this unit?
Thanks John Keep Computing !!!
This machine came with a green-phosphor, slow-phosphor screen that's sharp
and rock steady. The screen tilts up and down and left and right for maximum
comfort. It has a silent keyboard with a large shift key next to the Z, the
return key is also large, and the cursor-movement keys are separate from the
numeric keypad. The disk drives are 5 1/4-inch and hold 640k each and are
expandable to 1200k each. 128k of user programmable memory is standard. It
sold for $4995 new. It had a 16-bit processor like the IBM and you could
buy a plug-in card that increased the memory by 64k for $600 that also had
the Z-80 microprocessor on it and allows you to run CP/M. This was called a
Victor-80 Card. The 9000 does excellent monochrome graphics but it will not
do color graphics. Hopes this info helps John Keep Computing !!!

Do a web search there many rainbow sites that offer software for download.

It's decs a80/8088 powered alter to a PC.

Fall on floor laughing. While similar it's not upgradeable to a XT.
First off it has 768k of ram(or more) possible if not installed. Unlike
IBM they actaully fully decoded addresses for memeory so there are no
"holes" There is a z80 that does IO and it ran both CP/m-80/86(both!) and
MSDOS2.11.
<No video or whatever...
Should have a tube and LK201 keyboard as well as it has video and all. It
was a vastly better machine than the XT but not as accepted due to poor
marketing by DEC(actually none at all!) It was faster than the XT and had
at the time of offering better graphics.
<Is it a PDP relative?
Only in that it came from DEC. No PDP-11 or PDP-8 connection.

I used a System'34 when I worked for IBM in 1985-86. It was old then -
late '70s?. I seem to remember about 224K of RAM, possibly 256MB of
hard disk.
There were a number of posts on this subject on this list in late
September - start with the thread on IBM 5120 on 18th.
I would be very sad to see such a system vanish - I have a certain
affection for it after discovering that I - the newest student - knew
more about system/34s than anyone else in the building (this wasn't much
- the building housed two marketing units).
If you - or someone - do manage to acquire this sys/34, I may have some
spare copies of one or two pocket quick reference guides I could send
you. I'm pretty sure I've got OCL pocket reference (about 1/2 inch
thick) and I may have the Assembler pocket reference.
Finally, where is this machine? If it is in England or Wales I might
consider acquiring it myself...

This machine is in Boston, MA, USA. It also has three very ugly terminals -
anyone know what kind?

Enrico,
What your saying is you want a real Intel 1974 C8080D date code part!
That's the commercial grade cermet package part that was the initial
offering. Not an AMD, NEC or some dozen others, not all identical.
On the other hand if you really wanted all of the various permutations
of the 8080 and there are at least 4 or 5 (all pre 1979) I know of. You'd
have to consider the 8080a a find as that is still pre '79 design! You
have to qualify the vendor and mask set used of or if it was a reverse
engineerd design like the NEC parts the 8080, 8080a and 8080af. Of course
there were subtleties like the round lid uPD8080AFD or the square.
So if you are going to preserve history, you have to be a lot more specific.
Or otherwise an 8080A is really then just another 8080! It's the specific
part, vendor and die level aspects of the history you loose by collecting
those 40 pin slabs of plastic or ceramic indiscriminately.
FYI: the MDS I have has a intel 8080 cermet late 74 date code nonstandard
branding hand written part number. It appears to be a engineering sample
marking. I also have several dated copies of the 8080 and NEC 8080 parts
as they were different both in packaging and specifications. Never minding
the other intel one from my altair(early 75). The 6800D1 board I have has
a MC6800L, that's the cermet 1mhz part circa 1976(august if the datecode
reads right). Since I was designing with and using these parts I retained
samples that I never threw out as I figured some day I may use them again.
they are also part of the collection of processors that includes the DEC
T-11 single chip version of the PDP-11 chips I have with DC310es60
(engineering samples 4 of them). One of the ES parts is in a internal DEC
demo/proto board. Then there are the pre '79 SC/MP, cosmac, Intersil, TI
I know a bit about the history as I was one of the now older hackers from
then!

well, a cd disk cleaning kit only costs <$10. I myself dont even know how one
would clean a cd drive if it was taken apart as the disk cleaner would do
everything.

The BUS ERROR wasn't from the card not being installed. I reinstalled
everything, and it refuses to boot.
Apparently, I've snipped the wrong wires on the UDA50 slots.
Or forgotten to plug things in...
No, that's not it. EVerything's plugged in, the lights on the UDA strobe,
I've cut the wrong pins and boogered this up worse.
I really should stop destroying these machines and just pass them on to
more capable people...
But I like them too much. Where are the pins I am SUPPOSED to have
clipped? I'll rejumper the old ones, it doesn't look hard...
I saw your request for info regarding UNIBUS pinouts. I will try to look
them up for you... no promises though.
I have a complete set of 11/44 boards and a couple of 1 MB memory boards for
it. Would you be interested in them? Reasonable offers or begging will be
considered.
