<I have just done a search in the Jameco catalogue and although there are <some 8080A for sale the 6800 seem NOT to be available anymore..... I just got hardcopy catalong this week and also checked on line. They have it! The 8080A is the same thing and the 6800 also came in a B part (different speed). Allison

Kim Help

by jrkeys＠concentric.net

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 !!!

Victor 9000

by jrkeys＠concentric.net

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 !!!

System/34

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

6800

by allisonp＠world.std.com

<Well I want it for my CPU collection and therefore it is QUITE different <to me... < 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!

Bogus CD drive

by SUPRDAVE＠aol.com

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. david In a message dated 11/13/97 10:05:55 PM Eastern Standard Time, engine(a)chac.org writes: << My primary computer has a Toshiba 3401 (couple-years-old) caddy-type SCSI CD drive in it. This is from back when they were expensive and built like tanks. It is now generally choking on software CD's and skipping horribly on audio CD's. My Wintel guru says that it is literally not worth trying to clean the thing, that the cost of a cleaning will exceed the cost of a new 8X or 10X SCSI CD drive, and the bother of going inside the case, removing, and re-installing will be the same. I hate to pitch this drive, it's worked so well; is there anything non-invasive I can try before I give up on it? thanks much, __________________________________________ Kip Crosby >>

[11/34A] ARRRRGH!! <sound of head banging on wall>

by dseagrav＠bsdserver.tek-star.net

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...

11/44's

by JAiken8269＠aol.com

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. John Aiken JAiken8269(a)aol.com
