[sdiy] Yamaha PF10

[anthony]

Today at a local music store I found an old Yamaha PF10, "electronic piano" 
for $100. AT first I was turned off because it wasn't MIDI, a key was 
obviously broken and the knobs were off the sliders. But I played with it 
anyway. The voices sounded pretty good, but what I really liked was the 
"stereo chorus". It was a bit over the top, but in a really good way. So 
that appealed to me and there was tons of empty real estate up top - I 
figure I could add a MIDI interface and maybe some voltage controlled analog 
synth module guts. If anything I could just patch in my QY10 into the 
chorus.

Does anybody know what BBD's the PF10 used? Or where I can find schematics?

I don't think I've ever heard of a PF10. Is a beat up specimen worth $100?
