Circuit Overview:
     A digital synthesizer with fairly comprehensive workstation capability and expansion options. Many versions released with 61 to 88 key movements and racks.

Service Tips:
     I've found most of these units to be fairly rock solid circuitry wise. Watch for loose screws under the main board shorting things out. Glue those down!

While Yamaha normally does not keep parts around more than 5 years or so, they still support most motif I think.
