Re: Four Unibus boards from radiation dose measurement system.

There is two different kinds of test. One is to give them a fixed dose and then check to see if they are still operational. The other is to zap them until they fail, and then diagnose the failure/s. Dwight From: cctalk on behalf

The circuit board material of the straight 8 front panel is fragile. The resin used melts at soldering temperatures. As a consequence my front panel was munged up before I got it. Foils lifted kind of thing. I decided when I next took it apart I would replace with LED's. Around 1995 I had

Hello Folks. In the continuing saga of sorting through a big batch of Commodore stuff from my collection, I've listed 6 different early revision Commodore 64 computers for sale. Complete details and links to photographs are on the VCFed forums here:

Four Unibus boards from radiation dose measurement system.

Hello! I have four unibus boards that came in a 11/34 which was used for radiation dose measurement at a hospital. Three of them are made by Computer Design & Application inc and is a three board set interconnected with over the top flat cables. It has some kind of AMD 29xx based bitslice
