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". Contact me offlist (gooi AT oce DOT nl). - Henk, PA8PDP. _________________________________________________________________ Gratis bellen van PC naar PC?

ISO: Sony "WATCHman"

by THX1138＠dakotacom.net

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. Doesn't need to be in good cosmetic shape since I will disembowel it, regardless... Apologies if I have *stretched* the on-topic-ness on this one :-(

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?

It is a great day today (bought a vax 3800)

by vax9000＠gmail.com

After I dragged it home, I found there was not 1, not 2, not 3, but 4 MSCP disk controllers installed in this BA213 cabinet. They are, KFQSA, viking VIA/QTA, CQD223/M, USDC 1108. What a good day today! This is my maximum VAX 3800. My existing VAX 3900 is the minimum, by the way. vax,9000

Anyone recognize this PCB?

by elf＠ucsd.edu

Previously posted: >> Next, someone else is going to ask, "what's sex?" > Other than the 6809 did any other computers have the memonic > SEX - Sign EXtend? SDS/XDS and their Sigma 7 computer (and possibly ran on some of their other Sigma series computers?) had a hardware diagnostic program called SEX -- which was short for System EXerciser. -eric

TRS-80 Model II

by cc＠corti-net.de

Hi, A friend of mine needs to repair the power supply of a TRS-80 Model II. I've found a schematic but without part numbers and values! He needs to know the type of transistor Q1, there are no markings on the case of the transistor. I've checked the power supply of my Model II, and there are no markings, too. The Technical Reference Manual has all schematics for the Model II, but the schematic for the power supply is useless without component values. Might a BU208 for Q1 do the job? Christian

Ancient Genrad system

by kahrs＠caip.rutgers.edu

Looks like this contains tasty tidbits but it's too far away from me: http://cgi.ebay.com/genrad-2294-central-station_W0QQitemZ320017707724QQihZ0… At a minimum, it has some really deluxe 8" drives.

If it's purely by name then it can easily be switched for something much nastier without the user finding out. There used to be a fake "datatypes.library" for Workbench 3 on the Amiga. Instead of containing various datatypes functions/data (say for JPEG's, GIF's and IFF's etc.) it was a nasty virus. Personally I prefer Workbench 2 and have mine set up with my own custom icons and mouse pointers :) NB: For those that don't know, Workbench is the Amiga version of Windows - or should that be Windows is the PC version of Workbench :) Regards, Andrew B aliensrcooluk at yahoo.co.uk
