Hello David, I finally got at that info you requested. It turned out that there was some other related info that I thought you might like also. Probably more than you've ever wanted to know about SCSI, up to SCSI-3 info? Of course it was being stored on a SCSI drive that, at the time, wasn't hooked to this system, which is why I asked for your patience. Anyone who is interested must DL and save it within the next couple of days, as I have very limited web space and can't leave it there long. This is the only time I can post it. So, perhaps someone else with more space can host it for a longer period of time. http://members.bellatlantic.net/~vze2mj6m/scsi_info/scsi-info-15kb.htm http://members.bellatlantic.net/~vze2mj6m/scsi_info/scsi_faq-145kb.txt http://members.bellatlantic.net/~vze2mj6m/scsi_info/scsi2-spec-1632kb.txt Sincerely, Bennett

Slightly OT: What to do with a DEC 3000/300?

by ken＠seefried.com

Sorry to be late to this topic. As it happens, I've got a DEC 3000/300X (175MHz 21064, 64MB RAM, 2x2GB Disk, NetBSD 1.5.1 + fixes) in production. I'm fond of it, but probably more for the fact that it comes in a rackmount sled, which appears to be quite rare. It fits nice at the co-hosting facility (it's www.thistle.com, but it doesn't talk to anyone but me right now). What I know: Memory: No...you can't put just anything into it. It's got 8 72-pin SIMM slots, but it will only accept 8MB, true parity, generic SIMMs (giving 64MB). And it's damn finicky about those. My 3000s spits on SIMMs that everything else in the basement has no trouble with. It will also accept Digital custom 32MB true parity SIMMs (giving 256MB). Nothing else that I've found will work, but that could just be me. If anyone has any of these SIMMs they don't want, do let me know... Video: AFAIK, none of the free *nix systems support the built in TC frame buffers. VMS and OSF/1, nee Tru64 do. The 3000 will run X clients and display to another machine. Real men do serial consoles anyway. Speed: Slow. Really slow. Not PC532 slow, but not something I'd trade one of my PPro 200s for (other than the swanky rack-mount sled). Definately useful for low volume web, mail, etc., but "make build" isn't pleasant. My PC64-275 is way, way faster, but still not that fast. There's lot's of good info out there, and I know there are people working to support all that isn't currently supported. Drop me a note if anyone wants to know anything else. Ken

The stringy floppy is flawed the same way an 8-track audio tape is -- it only moves in one direction. As a result, A&J didn't write any OS for their drives, just a couple of simple commands. You search for the file you want, and you either find it (after several minutes) or you don't (after several minutes). > Anyone got a spare QOS wafer? Nope. Glen 0/0

Strange, but interesting, stuff. Ahh, neat! I've heard a bit about Wang VS systems, but I had no idea they were TTL CPUs. Very cool. How wide is the processor? The 74LS181 is 4 bits wide...how many does it use? Have you had a chance to take pics of this system? I'd be highly interested in seeing them if so. -Dave -- Dave McGuire Laurel, MD

Need info/manuals/software - Microtest 14 CD Dicport Tower

MicroTest is still around..

Cromemco Pick-up on 10-13-01

by jrkeys＠concentric.net

This pass Saturday was a long drive MN to IL (12 hours total drive time) to pick up 2- Cromemco System Three's, a Systemv CS-300, one new in the box KB for these systems, lots of manuals and software for them, a Cipher 1600BPI tape unit, a model BRZ-III fan for the units, and some parts. All will have to be cleaned up as they are pretty dirty and need some loving care. The guy had over 1600sq feet of computer stuff he is selling most on eBay.:-( At a local thrift I got some Sega master stuff, like the 3D glasses that have been selling on eBay for $50, I got mine for a couple dollars. Got a Virtual Boy system for $11.99. Got some Atari 2600 stuff also they were selling cartridges for 80 cents and they had two big boxes full. Now I will start the clean-up and entering all the info into the database (my paper notebooks). Keep computing John
