1960s Big Iron

by lproven＠gmail.com

An author friend has just put up one of his occasional retro-futuristic photoblogs. But this time, he has a selection of '60s mainframes which might amuse. They're the bottom section of tyhe post... -- Liam Proven ? Profile: http://lproven.livejournal.com/profile Email: lproven at cix.co.uk ?

More DEC things available

by paulkoning＠comcast.net

Since others are running ?DEC things available? I?ll add a few of mine. Free; I?ll mail them inside the USA. Outside the USA, please ask. a. Three Unibus jumpers, M9202 ? the kind with 3 feet of Unibus cable folded between the two circuit boards. b. One DEFPA-DA dual attached FDDI NIC, PCI interface. No software for it, but it should be ok though I?ve never used it myself. c. Two DEC Pro hard drive controllers (device code 401). One is labelled ?bad? though it looks physically intact; the other is not so labelled and also appears ok. Not tested. paul

Bernoulli 10 MB packs free if you can read them

by akb+lists.cctalk＠mirror.to

I have a stack of maybe ten 10MB Bernoulli box packs. I'm not sure what's on them; I think they came from a clean-out of a business I did in the 90s. If there's anything interesting on them, I'd like it to get archived someplace. Would anyone with a working drive be interested in reading them in exchange for keeping the packs? I'll pay shipping in the U.S. --akb

More DEC stuff I'm getting rid of

by elson＠pico-systems.com

Hello, I have the following items to get rid of: 1 KA650 with two M7621 memory boards and cabinet kit (without battery). 1 KA630-AA, cabinet kit, but no memory. 1 KA630-AA, M7608 and M7609 memory boards, cabinet kit. 1 VCB-02 with keyboard, mouse and VR290DA monitor. The monitor would be really difficult to pack for safe shipping, however. 1 DHV11 serial multiplexer. 1 CQD-223/M SCSI disk controller (made by CMD). 1 Dilog DQ153 G. (Pertek tape controller??) 1 AVIV mag tape control, might have been for Storage Tech tape drives. 1 M3106 4-line serial mux with dirty cabinet kit 1 Dilog ESDI disk controller (I think) 1 M7607 memory 1 Andromeda MFM disk and floppy controller 1 MSC Q-bus memory board 1 MSC double-widw Q-bus memory board 1 M7264 LSI-11 1 M7950 parallel interface board 1 Dilog DQ132 2 M7941 parallel interface 1 M8027 LP interface I can send photos or do other research to try to confirm the identity of some of these boards, if interested. I have some Q-22 and maybe Q-18 backplanes, too. Jon

"The search for the lost Cray supercomputer OS"

The original Cray OS (COS) was basically a batch OS. More than just a framework, but less of an OS than, say, OS/370. They were indeed front-ended by a host machine (the one at Pittsburgh had 2 (I think) VAX/VMS hosts) where you'd write and compile your Fortran, stage your data, and write a script to get everything submitted to the Cray run queue and collect the results. Later (mid 80s) they came out with UniCOS, which was a SVR2-ish Unix port which let you eliminate the front ends. I recall some vi-v-emacs level internecine warfare between the "UniCOS is awesome" and "all that Unix overhead is a waste of a perfectly good Cray" camps. Internally, Cray was committed to UniCOS, so that's who "won".

I've never really considered that it might be rare. > I suppose I should have also grabbed all the spares at the time I got tape. Yup. I know more than one FPS that ended up getting tossed because no one kept the software (and in one case, because the software was for a host that no one had any more). Unfortunate...they're really interesting devices.

Talking to Dave McGuire

by dgriffi＠cs.csubak.edu

It has been at least a year and a half that I sent my IOB6120 board to Dave McGuire for assembly. I haven't heard from him in a while. Does anyone know what's up with him? -- David Griffith dgriffi at cs.csubak.edu

External 5-1/4" drive for Tandy 1000EX

by drlegendre＠gmail.com

Does anybody have a spare external drive for a Tandy 1000EX XT clone? If not, is there a way to make a 'generic' 5-1/4" drive work with it? IIRC the 1000EX connector is a basic card-edge deal, probably 34pin. When I found the machine, the ext. drive wasn't sitting that far away from it, but not realizing they were a pair, I just walked away from it. Been bugging me for years, what a PITA with one drive, lol. Gotta gotta get it working. Thanks for any & all assistance!

MARCH's UNIVAC

by evan＠snarc.net

For the past couple of years we in MARCH have been teasing people with the knowledge that we have a UNIVAC mainframe. :) It's a model 1219-B (1965 transistor system) used on Navy ships for things like radar and weapons system control. This weekend we finally got around to taking some good pictures of it in our storage warehouse. The computer was a gift to us from the Johns Hopkins University Applied Physics Laboratory. Here are the five main racks: http://snarc.net/1219b/all_comp.jpg. Left to right: A/D converter (ignore the cable spools on its pallet), data recorder / IO hub, one of two identical tape drives, both CPUs. Here are three of the four IO consoles (paper tape below, TTY above): http://snarc.net/1219b/all_io.jpg. All are identical. The second tape drive and the fourth paper tape/TTY console are on on display in our museum. Now for some close-up pictures. 1. A/D control panel: http://snarc.net/1219b/close_control.jpg. 1a. Details: http://snarc.net/1219b/close_control_detail.jpg 2. CPU: http://snarc.net/1219b/close_cpu.jpg (unfortunately both CPUs are missing the top UNIVAC nameplates.) 3. Tape drive: http://snarc.net/1219b/close_tape.jpg 4. Data recorder and I/O hub: http://snarc.net/1219b/close_datarecorder_io.jpg 5. Paper tape / TTY console: http://snarc.net/1219b/close_io.jpg No, we haven't tried to power it up ... it might be another few years before we get there, plus, we're missing the core memory, software, various important cables, and most of the manuals. We also don't have the electronic terminal or the line printer. Still, it's one damn impressive-looking computer, and we're very proud to own it! For context: each CPU weighs about 1,500 pounds. Each tape drive cabinet weighs about 1,000 pounds (you can see it has two drives inside the cabinet; each is a 7MB, 7-track tape.) We hope to be able to take this out of storage and put it on static display at VCF East but that depends on a bunch of other factors, like whether our forklift is working, etc.....
