The Computerist's Video Plus board

by jlewczyk＠his.com

I just dug out an old single board computer which was made by a company called "The Computerist" which is called a "Video Plus", probably around 1981-82. Its a 6502 based board with the same form factor as the Kim-1 and I believe the same pin outs on the two 44 pin edge connectors. It has some 6522 vias and some video signal generating chip, a composite video output, sockets for eprom, four 2114 ram, etc. Does anybody have documentation on this board? I lost mine years ago when I sold off my old KIM-1 stuff :-( and would like to resurrect this board. Its in very good shape, but is missing some socketed chips. Need docs though to get anywhere. Any leads would be appreciated, even a contact to someone who ran the company or worked there could help. They had a lot of neat products! The COMPUTERIST, INc. P.O. Box 3, S. Chelmsford, MA 01824 Thanks! John Lewczyk jlewczyk(a)his.com

new addition: modified <?> PCjr <!>

by SUPRDAVE＠aol.com

in addition to getting a very clean PS2 80 and 65, i found a pcjr with strange modifications. a switch was added to the front of the jr that says: OFF/ON PC MODE. the computer sits on top of a case that's about XT form factor and it is called an EXTEC 1. It appears to have a hard drive, serial port and RJ11 jacks on it. a wide cable connects the jr to the extec. the jr also has 3 carts; one is jrVideo by pc enterprises, the second is pcjr clock cart by integrity tech, and one that says hardbios jr by MSC (HDD BIOS routines for the jr and RIM HD system it says) . also got an adaptor made by synetics sw and systems that allows two carts to plug into one cart slot. havent tested it yet since it rode home in the back of the truck and needs to acclimate to room temp before testing.

Again with the OT, free software

by af-list＠wfi-inc.com

Hi, Sorry to post nothing but junk, but I've been contacted by people on this list before who are active in donating/setting up computers for charities. Anyway, I recently came across 20 or so copies of Aldus PhotoStyler version 2.0 which are completely Spanish language. If there's anyone on the list who is doing work in Mexico/Latin America and want's these, let me know and I'll ship them out to you. Cheers, Aaron

MicroVAX 3 Question

by allisonp＠world.std.com

<OK, question of the day, how many RAM boards can a MicroVAX handle? It's <living in a Sigma Rackmount chassis. You have three limits. Available power, max address space and Q/CD slots. I cant tell you home many Q/CD slots you have or how much power. The max address space for the Microvax depends on version. So you can in many cases run out of addressable space if the other two parameters are not a limit. Microvax1 4mb (Q22 limit) MicrovaxII 16mb (implementation limit) MicrovaxIII/Cvax (32 or 64mb I forget which) Allison

My Y2K wishlist

by dylanb＠sympatico.ca

I am still looking for the following items and I hope someone out there can help: Centronics 704 printer (I think it's 704, maybe 104.. anyway, it has 4 heads, upper case only, 800 LPM) CalComp 563 or 565 or IBM 1627 Plotter MicroVAX 2000 (loaded) That's it. Please address any wishlists to me to wishlist(a)pdp8.com . That way I can catalog them and be able to fill them easier. Ie: someone asked me for docs to an RH11... I now have them available... who is it? john PDP-8 and other rare mini computers http://www.pdp8.com

Oldest machine I've ever seen for sale...

by aek＠spies.com

"Yes, and the current high bid is by about the best person I'm aware of for it to go to. He's got the space, and it *will* be safe. " No argument there!

by aek＠spies.com

"There is still 1 day, 5 hours to the sale close!" Which means the current high bid is meaningless.
