I used a 3.5" disk with the advent personality card configured so it looks like a 5.25 80track dd drive and I get 782k per disk (close enough for 720k(different number of sectors but otherwise legit)! The drive was mounted in one of the two hole vacated but the 360k HH drive using a 3.5" to 5.25 adaptor bracket. The 3.5" drive is an older one that has a select switch for one of four drives. A newer drive can be used but you need to make a "odd" cable. Allison

Windows 1.0?

by todd.osborne＠barnstormer-software.com

I have a copy of Windows 1.01 that I installed on an XT. What I am wondering, was there ever a publicly available 1.0? I cannot recall ever having seen it. Just curious...

photographing olf computers/parts

by lemay＠cs.umn.edu

Does anyone have any suggestions for ways to photograph parts of my collection? All i have is a basic 35mm camera and a polaroid... Should i use high speed 35mm film becasue of low light conditions indoors, or is a slower speed more important? Or is it important to have a white background for contrast.. Or should i try placing things on a flat bed scanner, etc.. Any suggestions are appreciated. I want to photograph some of my rarer items (Teraks, Sun 1, if you saw that Burroughs core memory that just sold on ebay I have one of those too plus a foot long chunk of wire-wrapped boards from that computer, etc). -Lawrence LeMay

Hello all!

by jlwest＠tseinc.com

I just found out about this list so I thought I'd post this here in case someone can help... I appologize if this is a repeat post! Looking for anything HP21MX or HP2000 related - cpu's, peripherals, etc. Many of the HP1000 system peripherals are of interest too. My particular interest is TSB (Time Share BASIC), not RTE, so I'm also interested in IOP Roms, etc. Especially interested in the following: 21mx series cpus and controllers 2748A or 2748B high speed paper tape reader 790x type disk drives (7900, 7905, or 7906) 7970 tape drive TSB 1541 rev c or later paper tape (binary, loader1, and loader2) This is for a private collection, hobbyist use (not business or resale) - does anyone have any of this stuff around in storage they'd be willing to part with? Please reply directly to jay(a)tseinc.com. Thanks! Jay West

Don't use too slow a film; for technical reasons, the slower the film, the more contrasty it's likely to be. Too much contrast loses detail. > I have little experience with lighting computer stuff, but I imagine (say) > a board full of chips might require several light sources to avoid the > chips casting strange shadows. Mechanic/electrical artefacts tend to have a lot of reflections, and it's usually better to use one main (preferably diffuse) light source with a big reflector on the other side of the subject, to fil in the shadows. A big white board, or a bedsheet will do admirably. If you do want highlights off the shiny parts, you can always add a small light once you have the main lighting adjusted. If you're using artificial light, even for colour negatives, you'll get better results if you use a colour correction filter on the camera. -- Pete Peter Turnbull Dept. of Computer Science University of York

Soviet BK-0010

by Anthony.Eros＠digital.com

Wow! That sounds all kinds of neat -- any chance you have a line on more than one of these? I'd love to add a "computer-in-a-keyboard" PDP-11 to the collection! -- Tony Eros Computer History Association of Delaware ---------- From: Andrew Davie[SMTP:adavie@mad.scientist.com] Reply To: classiccmp(a)u.washington.edu Sent: Friday, January 29, 1999 9:23 AM To: Discussion re-collecting of classic computers Subject: Soviet BK-0010 I recently posted about the Soviet BK-0010 computer. I've since found out a bit more information about it. I'm reliably told that it has an actual PDP-11 processor inside it - and I naturally assumed it was a PDP-11 clone. Its not. In fact, it is a computer-in-a-keyboard, somewhat akin to the Commodore 64. The whole thing weighs 2kg or thereabouts. It's a simple home computer. There are two versions - a membrane keyboard (with brightly coloured keys!) and a "normal" keyboard one. More information as it becomes available. And here I was, expecting to have to arrange shipping for something the size of a fridge! I'm trying to arrange pictures - I may extend my site to include Soviet Microcomputers, too :) But that would be "MOSMOW" and it doesn't have the same catchy ring to it. I need a new acronym!
