Disklavier

I have been asked to convert an imported Japanese Disklavier to local 
(Australia) voltage (240V AC 50 Hz). Not so difficult but I am 
curious to know the exact model of this unit.

What I know:-
1. The piano is a U30A Serial No. 48xxxxx manufactured c1990.
2. The controller has PPC-10MR written on it in English and is not 
mounted in Piano but is separate unit.
3. The innards look like MX100.

I would also like to know if remote control might be available 
anywhere.

Many thanks in anticipation ....................Leigh
