Any KSR-1 or 2s out there (OT-newer but rare)

by Innfogra＠aol.com

Is there anyone out there maintaining or know of a Kendall Square Research KSR 1 or 2 massively parallel supercomputer. Unfortunately a local scrapper got to the chassis but the cards & power supplies of one are available. Paxton Portland, OR

However the shareware/freeware counting part I agree it's questionable but often there are better out there than from the OS oem. Allison

Well, CP/M came with a good assembler, MS-DOS didn't. That's where I draw the line in my head. Admittedly the version of ASM that came with CP/M wasn't awfully featurefull, but it did work. And you got documentation for writing programs with CP/M. And admittedly MS-DOS commonly was installed with some version of MS-BASIC, but I (personally) don't categorize that as a "real" development tool. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

I missed the top of this, but I think this thread is about some older Modems, Motorola UDS's, yes? If I read what's gone on correctly, a four-wire device is for leased lines. You didn't even dial them. You just hooked them up and squirt away. Older two-wire modems, especially those that move sync data, are also lacking in dialing facilities. There was a seperate box that you routed the phone line through and sent commands via serial or parallel port to make the external box do the dialling. We used one when we were making sync comm equipment for VAXen more than ten years ago. I forget the first part of the designation, but it was a mumble-mumble 850 autodialler, the standard. Much later, ANSI invented an autodial protocol, V.25, IIRC. I have a Motorola 2400 sync/async V.25 _and_ Hayes modem from those days. It would work like a regular modem over a regular serial port, or if you used it in sync mode, you could send it V.25 autodial commands. One of my jobs back then was to retrofit the V.25 command set into our product. It was pretty cool when it all worked, but cool is a relative thing when you are working with stone knives and bearskins. -ethan _________________________________________________________ Do You Yahoo!?

VMS, all of the Unix clones, RT-11 to name a few still provide full development environment. I'm sure some(I would) here would add CPM OS9 and even PC based DOS(MS, DRdos, CCPM...). the amount of freeware or lowcost shareware for DOS/winders is quite impressive and plentyful.

Top 150 Collectible Microcomputers

by kaikal＠MICROSOFT.com

Polymorphic originally called it the "Micro Altair" until MITS threatened to sue them, and they renamed it the POLY-88.

Say Huh? The Poly-88 was not an Altair. It was made by a group in Santa Barbara. I have one, they were manufactured and sold as a product called Poly-88. Dwight

HP7900A drive

by jlwest＠tseinc.com

I talked to a guy that does 7900A repair today. He said from what I described that the heads are probably just in need of strong cleaning with a toothbrush, then touchup with 100% alcohol. As long as the gimbal isn't bent, all should be well. That takes care of the heads. Then you wrote... >I fixed a Plessey RK05-a-like drive years ago using a platter taken from >a standard RK05 cartridge. If you're lucky (and I was), the fixed platter >seats on a machined area of the hub/spindle and doesn't need to be >centred up. Otherwise you have to centre it with a dial gauge before >clamping up the screws. He also said the platter scapes make the platter almost, but not quite, useless; and that I definitely need a new platter. The lower platter on the 7900A does in fact seat on a machined area of the spindle and doesn't need special centering - "just bolt it on? - just bolt it on". He said I could use any 14" disk media that was the right thickness. Can't remember if it was 50 mils or 75 mils. I think it's the same as the RK05. I'll find out the mils number tonight when I compare my 7900 cartridge with my 7905/6 one. All I need to do is clamp a metal micrometer on the platter <just kidding folks!>. So - does anyone have a broken RK05 type cartridge that they'd part with so I can steal the platter out of it? >It's worth trying. Clean the platter as well. It can't do _more_ damage, >after all... True, but if there is so much scraped oxide that the badtrack list is 10% of the platter, why even bother. I've been quoted anywhere from $50.00 to $250.00 for a media only surface (no hub, which is all I need). Hopefully someone here can help out? Thanks in advance!!! Jay West

Does anyone know where I can find a working Commodore 64GS system? I've been looking for the last two years with no luck. Please e-mail me if you know where I can purchase one. Thanks, Bob
