This is two years late, but the terminal the original poster describes sounds like an IST (model 1), a CRT-based CDC product, vintage about 1978. There was a later edition called the IST-II, also CDC. It had two 8" drives and a Z-80 CPU, as well as connectivity to CDC PLATO mainframe systems, either by dialup modem (1200 bps) or multiplexer. The IST is not the oldest PLATO terminal, but it is the oldest that CDC manufactured, I suspect. Even my PLATO IV (Magnavox, 1971) is not the oldest, but only the first mass-produced machine. The earliest ones date to about 1961 and there are probably only two or three still in existence, if we're lucky enough to have that many. A precursor to these would be Norman Crowder's Auto-Tutor, vintage about 1958, which has characteristics very similar to the PLATO terminals (though it is not a computer terminal, it operates on filmstrip media), and PLATO's mechanisms are said to have been influenced by this machine.

MicroVAX equipment

by dan＠ekoan.com

It's been nearly a decade since I really dealt with MicroVAXen, but I came across a guy who has the following: MicroVAX 3600 uVAX 1000 RA81 (2) RA90 and some miscellaneous cards, in four cabinets. He got them in as part of a truckload of de-installed equipment and doesn't have any idea what they're worth. I'm at a loss as to what to offer for them, other than (of course) the lowest possible price. Any ideas on the going rate for this type of DEC equipment? He's also got a DEC MicroServer and some VT 510's. The guy was nice enough to give me an RL02K-DC removable disk pack (since he didn't know what it was or what it worked in), so he seems easy to deal with. (The disk pack did not come with the MicroVAX stuff.) Cheers, Dan

WTD: NEC D4164 DRAMs (CERDIP, with brass cover)

by philpem＠bigfoot.com

Hi, I've just seen an article on using a NEC D4164 dynamic RAM as a quick and dirty image sensor - I'm specifically after the version that had a brass cover. Prices negotiable. I'm after five or more of the little buggers (two to practise removal tactics on, the rest to modify and hook up to different computers). Alternatively, if someone's got a Micron IS32 going spare, I'd be happy to take it off their hands :-) Thanks. -- Phil. philpem(a)bigfoot.com http://www.philpem.f9.co.uk/

Anyone with info on Cipher C8803 tape drives?

by brian＠quarterbyte.com

Hi, I acquired Chad Fernandez's Cipher C8803 tape drive (and with it a lifetime supply of foam peanuts). (Thanks, Chad! Got the drive, the QBus adapter is on its way.) Does anyone have documentation and/or cabling and interface info (physical and/or software) for this drive? Or know of a scanned or other online reference for it? From what I read, Seagate ate Connor ate Archive ate Cipher and there's nothing left. Cipher Tape drive (open reel streamer) Model C880340-96-15250 Part Number 961210-001 Option B Thanks, Brian

Historically interesting (?) 'scope to anyone offeingr me anything interesting worth under $10

by r.stek＠snet.net

Dig out your old BYTE magazines and look for an early Circuit Cellar article about X-Y plotting. In it you will find a picture of a Heathkit IO-105 dual-trace 'scope. Well friends, THAT VERY SAME 'scope can be YOURS! This scope was PERSONALLY owned by Steve Ciarcia and became a fixture at the Circuit Cellar (even has a BEAUTIFUL, PROFESSIONALLY CRAFTED Circuit Cellar mylar sticker adorning the case) - and for an extra $5 I think I can get him to autograph it with an engraving tool ANYWHERE YOU WANT ON THE CASE!!! (sorry - seeing that post about DAK making a comeback has obviously done strange things to my brain) All seriousness aside, I got this from Steve, and it is in very good condition with only one small problem - it immediately blows its fuse whenever you turn it on. I loved Heathkits - they were just my speed - I could follow instructions, measure and cut wire, and I could grab the cool end of a soldering iron over 60% of the time. But without a manual and with no formal or informal training in electronics, to me it's just a boat anchor. I was going to toss it, but if anyone wants it, I can A) bring it to VCF East, or B) have it packed and shipped (it's heavy, bulky and obviously at least the tube itself is breakable). Just to make thing things interesting, anyone who can offer me a book, old computer magazine, Infocom CP/M disk or manual, NEC V-20, anything vaguely CP/M or 8080 / Z-80 /S-100 related, it's yours. No takers - its off to SallyAnn or Good Will (with a note attached stating its fuse-blowing propensity). Decision by the judges is final. Offer good only as long as I feel like it. For a list of the winner, send a SASE to: Bob Stek Saver of Lost Sols
