Yes finding a way to share the information you have would be a big help. Consider http://imagebin.ca if you can get the schematics scanned. The part of the schematic showing the motors/tachs/amps would be helpful, as would photos of any information on the servo motors. The more you can share, the better. Also, if you say where you are, maybe you'd be lucky enough to have an experienced retrofitter nearby who could have a look. Yes Seb and I used Mesa hardware for the interface. This machine had differential encoders on the servos already - we hooked them directly to a Mesa 7i33.
