I've got a couple of cubic feet of MULTICS manuals, here. Should I put them in the "to be scanned" pile or the "to be shredded" pile? -- Check what's already been done on bitsavers.

Microkernels (WAS RE: New to the list.)

Not sure if it's IPC or cheaper hardware, but large network operations on my Macintosh (System 10) bring the machine much closer to it's knees than any monolithic UNIX or even VMS on a VAX 4000/200. NB - I haven't used the microkernel based Tru64 yet. Microkernels are neat in theory, but a well-trimmed monolithic kernel seems to do pretty well with not too much space.

Genrad 2294 + PDP-11/44 In Atlanta

by jcwren＠jcwren.com

I went over and checked out that Genrad 2294 tester here in Atlanta. The auction includes equipment not shown in the picture, namely the whole Genrad test platform itself, and the PDP-11/44 shown in the picture. There are 4 DEC drives in the rack, plus one CDC drive (over the CPU), the CPU box itself, and two 8" floppies. Either I don't know the "trick" to getting the CPU box to slide out on it's rails, or it's jammed. In any case, I couldn't get a picture of it's guts. I do have some closeups of the exteriors of the CPU box, the CDC drive, and one of the DEC drives. Maybe by looking at them, sometime can determine what model they are. I'm going to pass on the unit, as it's just too damn big for me to put anywhere, and while they have a fork lift to load it, I have no way to get it off. The company bought the system while one of the Rockwell Missile System Division buildings either closed or moved. From what I gather, this Genrad was used in some phase of the Hellfire missile construction, although he wasn't clear if it was the manufacturing process group or the development group. There's also a bunch of good older test equipment, but nothing I have any use for or don't already have. The box hasn't been running in at least 3 years. I didn't get a look inside the chassis, but overall it looked pretty clean, no dents or major bashes. Seems like a damn good deal, for someone with the right equipment to transport it. --jc

Misc SCSI cards

by THX1138＠dakotacom.net

Hi, I'm digging through boxes in an effort to "lighten the load". Are any of these worth keeping? Future Domain TMC-840 TMC-850 STB Systems (no P/N... a pair of S3 *display* controllers onboard along with a DEC DC1040F -- which I assme to be a wide SCSI controller?) IBM (no P/N... three adaptec AIC7880's, a PowerPC 403GA, IBM "Viper" and "Rattler" chips. Lots of FRU numbers but no idea which applies to the *assembly*!) Thanks!

DEC 3000/400

by THX1138＠dakotacom.net

Hi, This box has a little fold down door in the front (below the half height CD-ROM/tape drive). It is the size of a second half-height drive bay. But, I'll be damned if I can figure out why it's there! Behind the door there is no way that anything *could* be installed (even if the opening into the chassis was NOT blocked). Perhaps this cover assembly is used for some other product(s) which *could* make use of the space behind it? (obviously, this isn't a material question -- just something trivial.... why go to the expense of putting something there that *only* serves as a place to hide the model number, etc.?) Thanks, --don

Nixdorf LK3000 (OT?)

by jim.isbell＠gmail.com

I hope this qualifies for a classic computer. If not then wipe it out. I have a Nixdorf LK 3000 and LK 3500 module that I was preparing to put on E Bay but discovered it didnt work. Examining it I discovered NO BATTERY, Inside there are a blue and a red wire that must have originaly gone to a battery clip. But I dont know what size or where it resided. I dont want to get rid of this without fixing it first. Does anyone have any info on what the battery (pack?) looked like on thei personal computer? I am glad I decided to try it out because I had remembered that it DID work. Shows what 70 years will do to your memory. I dont even remember removing the battery pack! -- Jim Isbell "If you are not living on the edge, well then, you are just taking up too much space."

Original boxes...

by wh.sudbrink＠verizon.net

Just wondering whether other collectors try to acquire original boxes to go with their machines. I have several original Ohio Scientific boxes that I prize as part of my collection. Anyway, I just got a nice Koyo 9 inch monitor (built 1979, IMSAI blue) in an IBM PS/2 Color Display 8515 box. I know that there are a few PS/2 collectors on the list. The box is not in the best shape, but it isn't awful either. Anybody interested in it or should I pitch it? Located in the Maryland suburbs of Washington, DC.

Compaq Portable III fails POST?

by Watzman＠neo.rr.com

I have a Compaq Portable III here, worked the last time it was powered (years ago), may or may not still work. I also have a file called "SP0316.ZIP" that contains "SP0316.exe" which, I THINK, is a utility (service pack) that makes the setup disk for the Portable III. However, it needs to run on a PC with a 360k 5.25" floppy drive. I THINK.

bad keyboard wires

by rtellason＠verizon.net

Just a thought on this subject -- do pretty many of these boxes have that _fuse_ that I've seen mention of in some contexts, which would kill the +5V to the keyboard if the old one had that bad of a cable? Something that may end up needing to consider here, depending o how bad that original cable was. -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, a critter that can be killed but can't be tamed. --Robert A.

Compaq Portable III fails POST?

by spectre＠floodgap.com

I think this one is on-topic. I got a Compaq Portable III dumped on my doorstep (more or less literally, actually), and while I don't really collect PCs, this one's form factor fascinated me. However, it seems like it's failing POST or its equivalent -- when I turn it on, the caps lock light on the keyboard (literally hanging on by a few threads) blinks, then the three lights on the front bezel and the 5.25" floppy light blink three times accompanied by three beeps from what appears to be the power supply?, and it just sits there, doing three beeps pause three beeps pause ..., until I turn it off. Nothing else spins up and nothing shows on the screen, even with me messing with the contrast. Any suggestions, or is there a troubleshooting manual to give me some starting points to see if I can refurbish this? Is the fact that the keyboard is probably incompletely connected to blame? -- --------------------------------- personal: http://www.armory.com/~spectre/ --- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- Klein bottle for immediate occupancy; inquire within. ----------------------

I need to get rid of a microVAX 3900 and some disks

by henk.gooijen＠hotmail.com

Hi all, I have a microVAX 3900 in a small cabinet (approx 90 cm deep, 105 cm high) that is taking up place that I really need. AFAIK, the 3900 is in working order, and I have also an RF215 (?) smallish tower with some disks in it. I need to check if you are interested. If you don't want the cabinet, you can get the PSU and the 3900 "crate", but given their weight, I am not going to ship it! That would get costly, but you could try to talk me into it :-) Contact me offlist (gooi AT oce DOT nl). - Henk, PA8PDP. _________________________________________________________________ 500 foto's per maand uploaden, GRATIS! http://spaces.live.com

I want to get rid of a HSC70

by henk.gooijen＠hotmail.com

Hi all, I have a HSC70 in a small cabinet (approx 90 cm deep, 105 cm high) that is taking up place that I really need. It's too crowdy. AFAIK, the HSC70 is in working order, and a tech told me that it is fairly equipped internally. I can't tell, I don't know anything of the HSC70. If somebody is interested, I can rip boards etc, before it goes to the trash :-( Somebody who wants the whole thing, comes first, as I am still hoping it can have a good "life".

Marginally on-topic (?) -- the watchman is "old", and the intended application is a "computer" ;-) I'm looking for a working Sony WATCHman (NOT *walk*man) for a wearable I am hacking together.

IBM 836 Keypunch

by roger.holmes＠microspot.co.uk

I don't suppose anyone can help, but I'll ask anyway. I have an IBM 836 Keypunch, which is similar to an 026 keypunch but has a patch panel in a pedestal to the left of the users knees. It also has three 40 pin connectors on the back panel. Does anyone know the capabilities of these? Where can I get matching plugs? The logic levels are presumably suitable for the relay logic within, but any idea what actual voltages and amperages are?
