Our club has had a Celestron CI700 donated to us. It has one issue, the slow motion control for Declination does not work in one direction. I have eliminated the motors, cables and am down to the circuit card. I can't find a schematic for the board, but am fairly confident that the issue is with the programmed chip (U3) on the track control board. It is a Atmel AT89C5216PC which you can still buy, but I would have to find a way to program it. The Celestron part number is #60830.

If anyone has any ideas on how I can fix this, or have electronics for this mount or parts, I would be interested in what you have..

If I can't fix it, I may list it here later as a fixer upper. Ping me if you are interested in that as well.
