I just finished repairing a SCI Model 700 Programmer first version. There is some information on the Rev 1 version but I could find no information on this first version. I created a web page with some documentation, photos, and scope and logic analyzer waveforms. Hopefully it can help someone else working on theirs.

I was unaware of these units until I got this one - it's got some nice features.
