New pictures; UYK-20 Computer and Millennium uProcessor System tester

by rigdonj＠cfl.rr.com

I've added some more pictures to my website. The first ones are of one of the UYK-20 computers. These were made by Sperry Rand and are militry versions of the Univac and use core memory. <http://www.classiccmp.org/hp/UYK-20/>. The other pictures <http://www.classiccmp.org/hp/millennium/> are of the Millennium microproccessor tester that was discussed here a few weeks ago. I took these pictures in a hurry and they aren't real good, particularly the ones of the Millennium. It was in the back of a dark warehouse and the pictures show it. One item of interest on the Millennium is the pullout drawer on the side. It has the CPU and all of the CPU spcific items on it. In other words, you can change it from an 8080 system to a 6800 system by merely changeing that drawer. I have two of these and IIRC one is 6800 and the other is 8080 based. Joe

Altos 686

by bmachacek＠pcisys.net

I just noticed I have an Altos 686 (without a cover) PC in my stack of 'old computer stuff'. It's s model 25A with one 5 1/4 inch floppy drive and a Seagate ST225 hard drive. Is this one of Altos computers that people are interested in or something that needs to be scrapped? Thanks for any help you can give me. Bill Machacek

DECmate II

by aw288＠osfn.org

Another item that will be leaving my collection (mostly because I never did anything with it) is a DECmate II - the micro version of the PDP-8 (Intersil 6120 based, I think). A couple of questions, as I would like to test the thing out before I offer it to anyone. 1) Whay kind of video is "video"? Some sort of odd tube? Whatever it is, I don't have it so I am hoping the box supports a dumb terminal. 2) Will I boot this up from a dumb terminal (VT100, my guess)? What are the specifics? This machine is in decent condition, with an RX50 and a hard disk of some sort. I have no manuals. William Donzelli aw288(a)osfn.org

Lear Siegler ADM3 terminals

by MTPro＠aol.com

<< I recently sold one in good condition for about $50 or $60 I think. >. Oops, I sold an ADM 5 on vintage.org marketplace for $79. That was in mid-February. I guess these are worth more for the lower case text? Best, classiccomputing.com

Manual for HP 82928A System Monitor?

by dan＠ekoan.com

Hello, This weekend I picked up a Hewlett-Packard 82928A System Monitor, which is a plug-in module for the HP 85 desktop computer. I have the box, the cartridge and a two-page "Installation Sheet", but no manual. Does anyone have a manual for this module? Cheers, Dan www.decodesystems.com/wanted.html

Sun Ultra 1 questions

by julesrichardsonuk＠yahoo.co.uk

See my other post about the Ultra 1 I found. (I think it's a couple of years too new to be on-topic - sorry!) I put the pair of memory sticks in there which I got in the same day and tried powering the machine up using a terminal as the console. Amazingly, it's alive! At the moment it's set to boot from the network - any idea how I can interrupt that and get into the boot monitor in order to switch that off? I think there's some key combination to do it from a keyboard, but of course I don't have one handy at the moment - just the console. There's a clear perspex bracket above the CPU for holding a fan, but no fan. As this machine had been stripped before I got it, I don't know if it should have one and someone had taken it out. The CPU has a large finned heatsink on it - on the web I saw a vague report that Sun may have stopped putting fans in the machines on later ones and just used a larger heatsink. Any ideas? Finally, any clue as to whether the Apple SCSI CDROM I got will work in the Ultra? It's a 1993 vintage drive, an "AppleCD 300 Plus". If not, I do have a SCSI drive that'll do both 512 and 2048 block sizes, but it's in a running machine at the moment... No idea why this machine was thrown out. It seems to work so far. Maybe it has an intermittant fault when it's been running for a while, or maybe the network interface is dead (according to console messages it notices when a cable's present or not though). cheers Jules

DEC RK07 drive interface specs wanted

It's also worth pointing out that by the '80s, some of the boards required diagnostics and equipment that it wasn't practical for every field service guy to carry. A lot of companies did as the one I worked for: field service engineers were trained (quite carefully) to pin a problem down to a board, replace that, and send the faulty one to their central workshop (ours was in Stoke) where it would be repaired and tested. There's nothing wrong with swapping a board providing you know which to swap (implying "why", at some level) and the faulty one gets fixed (assuming it's economic). -- Pete Peter Turnbull Network Manager University of York

DEC ROM and RAM boards

by Lee.Davison＠merlincommunications.com

Remembered to bring the details ... The ROM board is marked .. "5419803 5019802-01 A1" and "ROM DWT CARD" .. and holds 14 27C010 1Mb EPROMs. The back has a label saying "VT1000 2.2" I can use these EPROMs so if no one needs them or the contents they'll be recycled next week. The RAM card is marked .. "5019806" and "5419807" .. and has one 1MB SIMM marked .. "5419805" .. I have no use for this at all.
