Poly-800 Schematics?

[Glen]

I just acquired a broken Korg Poly-800 synth and I'm hoping to find a
schematic for it. The unit's VCF, noise generator, envelope generator, and
modulation generators all seem to work. The big problem is there are no DCO
signals present!

Does anyone know of an on-line schematic for the Poly-800? If so, please
either post to the list or email me personally.

Thank you,
Glen Berry
