Kinda sad actually, once Cray left CDC they didn't have a clue as to what to do afterwards, the big iron Cyber 6000s went nowhere, the company wound up running payroll services (the remnants of CDC are now known as Ceridian, a batch payroll services company).

Freebies up for grabs!

by kyrrin＠jps.net

Time to clean out at least part of my garage, especially in light of the new arrivals. All offerings are freebies, though it would be nice if I could get -something- in trade. ;-) Please bear in mind two things. 1). I cannot ship anything other than the books. The disk and tape drives are too darn big and heavy, and would require specialized packaging in any case. 2). Dave Jenner has first pick since he E-mailed me this morning before I posted the list. I'll post an update if he wants any of the stuff. With that in mind, I have the following to offer: 1). HP 7974 9-track vertical tape drive, with all mounting hardware. 1600 BPI, Pertec interface, supplied with the hardware to convert it (if desired) to a GPIB interface. Excellent condition, powers up and loads fine, have not actually tested it with a working system. 2). (Definitely a freebie!) 83-84 vintage System Industries SMD disk drive. Spins up, makes lots of noise, don't know if it works. Comes with mounting rails. 3). Cipher 880 tape drive, dual-density (1600/3200). Condition: Who knows? Freebie. 4). Books! I've got spare copies of: DEC's 'Microsystems Handbook' for 1985 DEC's 'Introduction to Minicomputer Networks' vintage 1974 Everex 'Step 386' owner's manual DEC PDP11 'Programming Card' quick-reference, vintage July 1975 DEC DHV11 Technical Manual. Any takers? -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Sysop, The Dragon's Cave BBS (Fidonet 1:343/272) (Hamateur: WD6EOS) (E-mail: kyrrin(a)jps.net) "Our science can only describe an object, event, or living thing in our own human terms.

Junk sale (new offer)

by fmc＠reanimators.org

Doug Yowza <yowza(a)yowza.com> wrote: > I don't remember ever seeing a desktop PC coming from them. Anybody know > how rare this box is? Sounds like a keeper. Yup, they made desktop PC-compatibles for a while. I remember a dealer in College Park, MD selling them (Software'n'Things if anyone else out there remembers them; to the best of my knowledge they aren't operating under that name anymore if at all). One of the big selling points was that they were upgradable by virtue of the passive backplane. Buy an XT-compatible now, later on you can upgrade to an AT-compatible just by swapping the CPU card for the '286 flavor. BTW Doug, is that your face I saw gazing up at me from this morning's San Jose Mercury News? If not, there's some guy calling himself Doug Salot who has some stuff in his collection that's an awful lot like things you've mentioned on this list. -Frank McConnell

Sam Ismail <dastar(a)wco.com> wrote: > Yes they were dot matrix. I always equated line printers with dot matrix > printers. Is there a difference? When someone says Line Printer I think of something with the type on a chain (or a drum) and the ribbon in front of the paper, and then a bunch of hammers behind the paper. When the right character is in front of the right position, the printer fires the hammer for that position and pushes the paper up against the ribbon and chain/drum. But the real definition is in how much data you have to send to the printer to get it printing. If you have to give it a full line to get it going then it's a line printer. If you only have to give it a character to make it print then it isn't. -Frank McConnell

Well the F8 while known was not hobbiest fodder being aimed at embedded systems. Same can eb said for z8. The 9900 as I refer to it was not the TI99/4a(have those too) but a Technico SBC, due to a lack of TI support it was not that popular. However the TI99/4a is still quite popular. Others I've worked with 78pg11(uCOM78) were aimed at embedded applications. I might add that my time as a product engineer at NEC in the early '80s had me designing in that part as well as supporting it along with ucom4 and ucom75 4bit micros. The RCA1802 was sort of a square egg. It had popularity for a short while. People lost interest after that, partly as RCA discontinued it by the mid 80s. Also because it was slow and had a relatively poor(primitive) instruction set and a total lack of high level languages other than tinybasic. The advent of more complete systems like apple and trs80 and decreasing prices helped focus the market on two key players 6502 and z80 and it would remain that way until the 68000 and 8088(x86) would displace them.

Well, do you know if it's oiled or unoiled? I'm not sure but I think I may need the oiled. I need to ask someone. My wife says that this tape I have has the distinct smell of machine oil. It should make the punch block last longer. I was just going to order a 1/4 case from Western Numerical Control (http://www.westnc.com/paptape.html). That's 7 rolls for $33.00, in all kinds of colors. And they are close by in Grass Valley,CA. I also want to ask them about the toxicity of paper tape.

Info on Teletek SBC-1

by allisonp＠world.std.com

< Does anyone have info on a Teletek SBC-1 Z80-based single-board <computer? Copyright is 1981. It's loaded except for RAM (from what I can <see). It has a Z80 CPU, PIO, SIO, and CTC. There are a couple of blank <sockets, and a TMM2016P-2 memory chip (a 2716??). It appears to be built <a S-100 card. First off 2016 is a byte wide ram. I sounds like someone stripped the card. The SBC-1 was a complete Z80cpu(4 or 6mhz)/64kram/eprom/IO card it was designed to be used as a slave to the Systemaster cpu card. The 2016 was used to create a FIFO so that block IO coul be used to communicate with it. the only thing it lacked to be a complete S100 cp/m system on a board was disk IO. The system master card had all that and FDC as well. Allison

Logic State Analyser

by jolminkh＠nsw.bigpond.net.au

I have been rearranging my storage area and uncovered a HP 1611A Logic State Analyser fitted with a Z80 option that I picked up a few years ago. I have no idea what one would do with this. Should I cherish it? Play with it? Does one need the specific manual or are these generic and perhaps explained in standard texts? There are a number of plugin points for various types of probes, none of which I have off course. It powers up fine though.

What a haul!

by kyrrin＠jps.net

Indeed, what a haul (at least if you're into DEC stuff). Thanks to the kindly folk at St. Martin's College about 40 miles south of me, I am now the proud owner of: * A PDP-11/44 and its rack... * A Fujitsu 'Eagle' drive (and it's weight!) * A Cipher 880 front-loader tape drive... * Numerous distribution tapes for several versions of RSTS/E, including one for ver. 9.7(!)... * Various bits of documentation. Unfortunately, not a lot on RSTS itself (much of it got trashed along with the -- get this -- distribution kit for RSTS 10! Dang, I was pissed when I heard about that...) And, thanks to my friends at RE-PC, I have also acquired a pair of M4 Data model 9914 9-track SCSI tape drives. These are neat boxes! Quad density (800/1600/3200/6250), autoloading, neat front panel with alphanumeric display, etc. It's been a busy weekend. Now, if you'll pardon me, I need to go collapse and snore my brains out. ;-) -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Sysop, The Dragon's Cave BBS (Fidonet 1:343/272) (Hamateur: WD6EOS) (E-mail: kyrrin(a)jps.net) "Our science can only describe an object, event, or living thing in our own human terms.

Junk sale

by william＠ans.net

...mostly because I do not want to throw the stuff out/scrap it... (1) Miniscribe 8425SA drive, removed from a Mac Plus. I assume it works still, but do not quote me on that. It seemed to power up fine just a few minutes ago. The Mac was in very poor condition, so that got scrapped. (1) Kaypro 81-045-02 PeeCee. This appears to be their version of the XT (oh, joy), but unlike most clones, is a little better built. It uses no motherboard, just a passive backplane with a CPU card. This one has a 20 meg Seagate drive and a Samsung (yuck!) CGA tube. It works, and has only DOS 5.0 on it. The nice thing about this is that most of the chips are socketed! (5) Ink ribbons for the IBM 5103 printer. Still sealed, these come with a goofy plastic glove for the CE. OK, so there are probably not even five 5103s left in the world... (1) Computer Wharehouse Store catalog, Spring-Summer 1977. SWTPC! Imsai! Kim-1! $1200 floppy drives! A slice from the "good old days" of the micro. The pages are a bit yellow, but in good shape. The cover is also nice, but the previous owner scribbled his name on the top. Really, if _anyone_ wants any of this stuff, speak up and make a SILLY offer. I will ship anything but the Kaypro (I could deliver it to RCS/RI in Providence, RI, however). Trades are good for the stuff as well. Not first come first serve - I will decide "winners" in a day or two, just to give those with restricted or slow email a chance. William Donzelli Carmel, NY 10512 william(a)ans.net
