Guys: I just picked up a CDC 9720-500 Sabre 8" drive (SCSI version). Anybody got docs for this thing? Especially the power hook up, and dip switch settings. (Now I have to scare up +24v @ 3A). A scrap dealer near where I work just tossed three of these that were SMD! Arrrrgh! Thanks!

E-Over Pay strikes again! original Altair disk sells for

by allisonp＠world.std.com

< Just remember that they're hard sectored disks with 10 sectors. I just <found a box of them in a surplus store a couple of days ago. Apple or PCC/altair minifloppy? if yes then wrong. They were both soft sectored. It was the 8" altair disks that were hard sectored and it was 26 sectors if memory hasn't lost a bit. Somewhere in the junkbox is a Pertec minifloppy controller for s100 that how I know, it's 1771 based. 10 sector was most commonly Northstar* MDS. Allison

Intel 4040 - was Intel 4004 simulator and tools

by allisonp＠world.std.com

<I'm getting this opinion straight from Ted Hoff himself. I don't know <where my notes are on this and I can't remember the details, but I think <there are some significant differences between the 4040 and 4004. The <8008 was supposed to have been based on the 4004 architecture, extending <it with more instructions and such. The 4040 was, I think, a whole <different design by a different team inside Intel. The 4004 and 4040 are very similar. the 4040 adds a few things like extra registers. The 8008 is really a 4040 stretched to 8bits. The 8080 is really pretty close to the 8008 though not object code compatable. I have the intel books on them so it's not like I didn't check. ;) Allison

Intel 4004

payroll as well as it did 20 years ago. Printers are faster too, I guess, <but since the essential demise of multi-part paper, it takes about as long <to generate the 4-part documents as ever. Huh? The company I work for has 35pc and an intranet but invoices and 6 part sales orders are still punched out using Epson 1624s and Diablo H-IIs! Allison

E-Over Pay strikes again! original Altair disk sells for $102.50!

by joe＠barrera.org

Don't forget to do the same thing for VMS source (alpha and vax): http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=62831750 http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=62837222 These went for $265.00 and $232.50, respectively. Having VMS source would be cool. But were these disks readable? Did they even have anything on them? Who knows. All the seller knew (said) was: Don't know much about this one ... its a four disk set .. I dont have the books or the box it came in. It says on each disk "OpenVMS Alpha V7.2 Operating System" then "Source Listings". Think of the possibilities. NT Source on CDs... Windows 98 source... use your imagination. - Joe

Off Topic? Anyone have manual for IBM 4019

by rcini＠msn.com

I got an old IBM laser printer this weekend from a friend of mine. It's the IBM 4019. It's not a Lexmark one, but one of the old workhorse "leave it running 24/7 and it'll outlive all of us" IBM printers. Weighs a ton. Does anyone have a spare manual for it that I can get? Thanks!

I think the Amstrad looks better :). Whups, 404 is the hospital room # my dad is in... it must have worn off on me. 8^) It's http://www.sinasohn.com/clascomp/altima2.htm all spelled out. But, I'll agree, I do like the Amstrad better. --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

question about a tandy 1000

by roblwill＠usaor.net

I have an original Tandy 1000, a 1000TL, a 1000SX and a 1000TX. The TL is the only one that boots from ROM. The older ones didn't. I agree in the fact that they're not worth much. The SX and TL were complete systems (TL had an EGA monitor), and the SX and the original were floppy models. I got them all for free, all working. -- -Jason Willgruber (roblwill(a)usaor.net) ICQ#: 1730318 <http://members.tripod.com/general_1> -----Original Message----- From: Steve Robertson <steverob(a)hotoffice.com> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Tuesday, February 09, 1999 12:01 PM Subject: RE: question about a tandy 1000 >On Tuesday, February 09, 1999 3:25 PM, Michael A.

[Amstrad PPC512] >Strange looking computer IMHO. It's the only laptop with a full-sized >keyboard (including cursor pad and numeric pad). The thing is wider than >a PDP11.... Nope... How about the Altima 1 and 2? (See http://www.sinasohn.com/clascomp/alt2.htm) Not quite the standard layout, but still a full keyboard, iirc. I think also, some of the new machines with the 15" screens have full keyboards. But yes, the PPC512 (and PPC640) are definitely odd ducks! --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."
