I recently removed a PianoDisc player unit from a vertical piano.
It's complete except for the control unit (where you put the discs).
It's not marked, but I think it is a PDS-32.  The circuit boards
are dated 1992.

I plugged it in and the power supply hums like they normally do.
I think it works.  The solenoid plungers have a very light rust
which can be easily removed with a 3M Scotch-Brite pad.  Asking
$100 plus postage.
