I'll hold off bidding on this in case someone else wants it more than me: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=4193&item=5134822428… Starting bid is a stimulating $2,050.00. But you Instant Gratification types can take this gem home for a measly $3K - Buy It Now and save yourself the stress of a damn auction!! Let's see if it stays this way, or if somebody hits the seller with a clue-stick. Cheers Granino Vanevar Bush-Korn

new find: an Intel MDS 800

by klemens.krause＠informatik.uni-stuttgart.de

I have a white MDS 800 System. It was sold in Germany by Siemens and they relabelled it to SME 800 ("Siemens Microcomputer Entwicklungssystem"). It has an external 8"-double drive and a dumb terminal. Inside it is all Intel. The only thing they changed internal: The glued "Siemens"-labels over the original Intel-logos on the PCBs. You can see it: http://computermuseum-stuttgart.de/dev/sme800 We are running ISIS-II inclusive KERMIT on it. One time Christian Corti succeeded to boot a CP/M 2.?. But in the meantime this disk was damaged. I found a very old CP/M source, dated "11/21/75" in the net, written in PL/M and was able to translate it with the original PL/M-compiler written in FORTRAN (dated: JAN 1975) on our SUN 4/260. What is needed: To adapt the original BIOS for single density disks to the double density drives on our system and to make bootable floppies.

I have the 135-U/A model, but no manual so I am a bit lost as to how it can be used. Does anybody have any information on how to use this multiprogrammer? Thanks **vp

DEC qbus Q/CD

QBus backplanes are normally soldered, with short pins, not wirewrap. I don't know if that's true for H9270, though (which I assume is what you have). There's a diagram with the info you need for Qbus in most QBus processor handbooks, in the chapter on the bus. The CD interconnect is described in the chapters on backplanes in the Microcomputer Interfaces handbook. If that won't do, most of the info is on my QBusConns.ps diagram at http://www.dunnington.u-net.com/public/PDP-11/ . In essence, almost all the signals on A and B are bussed all the way down, pin for pin, except the following: SSPARE[1238]: AE1, AF1, AH1, BH1 are normally not bussed MSPARE[AB]: AK1 is connected to AL1 at each slot, but not bussed; ditto BK1+BL1 SSPARE[4567]: BDAL18-21 on Q22, are bussed on Q22 backplanes PSPARE[12]: AU1 and BU1 need not be bussed - nothing should use them BIAK[IO]: BIAKI (AM2) on each slot is connected only to BIAKO (AN2) on the slot below BDMG[IO]: BDMGO (AS2) on each slot is connected only to BDMGI (AR) on the slot below (I'm not absolutely certain about the last, but I'm fairly sure that's right.) On C and D, pretty much everything on C2 and D2 of each slot is connected to the corresponding pin on C1 and D1 of the slot below, except: CA1 on each slot connects to CC1 on the next slot down CT2 on each slot connects to DT2 on the next slot down CA2 and DA2 are bussed to +5V CC2, CD2, CT1, and DT1 are all ground On the top slot only, there's a jumper between CK1 and CL1, and another between DK1 and DL1. -- Pete Peter Turnbull Network Manager University of York

Subject: Big Iron available - Data General Eclipse - plus lots more

The circuitry is all TTL (but there's a lot of it!); the manuals for operation and service are on the Internet; I restored two and got new CRT's for them (around $40 each shipped, as I recall, in black and white, natch). I really hate fooling around with CRTs but it was fairly easy. They are also very small, considering when they were built. One of mine didn't have the lower case option and I made one out of a 2716 and a little adapter board. It is possible to put in a metal plate or recreate the LSI logo on the switch cover (I did both). If I had room, I'd get a few more; it would be a shame to see these get crushed. They are the quintessential 70's generic terminal, are a perfect match to 70's pioneering home computers, and they have a certain Eames era look. Did I mention that I like them? ===== -Steve Loboyko Incredible wisdom actually found in a commerical fortune cookie: "When small men cast long shadows, then it is very late in the day."

Wrote some useful tools for PostScript

by msokolov＠ivan.Harhan.ORG

Hi folks, In case anyone is interested, I have just written and released some useful tools for PostScript lovers. These are: t1free - A toolkit for working with Type 1 fonts antidistiller - A special for those who (like me) love PS and hate PDF You can find both on my anonymous FTP server ifctfvax.Harhan.ORG in the directory /pub/PostScript . Enjoy! (Hopefully this isn't too far off-topic: after all, Level 1 PostScript is on-topic even by the stricter 20 y rule.) MS

VCF stuff for sale

by marvin＠rain.org

With VCF comming up in about 8 days, I am planning on bringing a bunch of stuff up there to get rid, er, sell :). In that vein, is there anything special those of you who will be attending are looking for? My plan is to reduce my collection to things that are primarily in the 70's to very early 80's, and I will mostly concentrate on CP/M and S-100 systems. Things I have that are not in my area of interest or expertise include: SparcStatation2 w/ external CD-ROM, Color Monitor, Keyboard, Mouse, Working Wang computer (don't remember model), about 10"w x 24"h x 30"d., untested Xerox computer, Model 8???, w/ monitor/keyboard. About the same size as the Wang, untested Phillips computer, about 24"w x 24"h x 30"d w/ 8" drive(s), untested Make a reasonable offer, but I won't be bringing the above stuff unless someone wants it! As usual, I'll post a link to the list of stuff that I'll be bringing up.
