So what is it with computers and Mondrian? http://www.computerhistory.org/revolution/the-web/20/390 (A little joke for those who remember a very old thread.)

Smoke From PSU Socket

Should I just be thinking of replacing the socket? Many "IEC sockets" are more than just sockets, and incorporate EMI suppression components as well. The euphemism becomes "power entry module" instead of "socket". The EMI suppression components (especially capacitors) in them are specced for AC line voltage applications and UL rated such, but they still let out their magic smoke every so often :-). Even if it's just a socket, some debris can get in there during storage, you plug it in, the debris trips a fuse and vaporizes, and all you're left with is a charred socket. Tim.

ohio scientific haul

by starbase89＠gmail.com

Hello! Yesterday I brought home a pile of OSI equipment. I got a Challenger II (in the blue, rectangular case,) a Challenger 4P case with keyboard (seems to connect to the main box as a keyboard,) two 5.25" disk drives in the style of the 4P and two joysticks. Inside the challenger are the following boards: 505 Rev B CPU/IO/Floppy 527 24k RAM 540 Rev B Video 567 Votrax Speech Synthesizer w/ external module; The Challenger II seems to have a well modified power supply, including and an added circuit board with two transformers, as well as four volt meters, mounted in cardboard and taped to the inside of the case. My first question in what is likely to be a long series is: If I intend to try and get it running, what is my first step? I'm not entirely sure what I'm going to do with the system yet. Its the first time I've had something of this caliber. I have no idea what its worth Thanks Joe -- Joseph Giliberti Jackson, New Jersey Come Visit the InfoAge Science History Learning Center and Museum Get more information at http://www.infoage.org

HP 82321B BASIC LANGUAGE PROCESSOR (VIPER) for $625 ?

by glen.slick＠gmail.com

Things that make you go hmm? HP 82321B BASIC LANGUAGE PROCESSOR (VIPER) http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=390281098409 Sold for $625 Are these really that hard to find? I think I paid somewhere around $30 or so each for my Viper and Hyper-Viper boards on eBay a while back. Maybe someone had one in a production environment that failed and absolutely needed one to get back online? With that sale price maybe a few more will show up on eBay (maybe I should list mine...)
