Discussion about the Korg PolySix synthesizer

I think I may have stumbled upon an old Korg MS-01 pedal in a pawn shop, I got it for $10 in a non-working state (I have yet to test it).

   It's a korg pedal, and has the same design as the MS-01 but is missing nameplates.  Maybe i'll post a picture when I'm home from my trip.  

Is anyone aware of alternatives to using the MS-01, or have the schematics for it?
