[sdiy] How to sell a Polly61?

[Ben Stuyts]

Hello everybody,

I bought a Poly61 on a flea market a couple of years ago. It has been 
standing in a corner ever since, waiting for some time to fix it. (As are 
some other keyboards...) Some of the keys, switches and pots have contact 
problems, but it basically seems ok.

I'd like to have the schematics for it, Are they available somewhere? Last 
time I looked on the net I couldn't find any.

I also understand there is some sort of cassette with the factory-presets. 
Anybody have this?

Thanks,
Ben
