Does anyone have a service manual to the Fisher AD-850 CD player they
would be willing to sell? This is an early model from 1983 that I'd
like to get going. I need to repair an apparent control logic
problem. The laser reads the disc fine, but it seems to get stuck
reading the TOC. It will play the entire disc as if it's reading the
TOC. I suspect that either the TOC data isn't getting to the micro
controller, or that the RAM used to store the TOC is not working.

I can use it on paper, fiche, or a pdf.
