Discussion about the Korg PolySix synthesizer

If the crystal oscillator is running, reset in is high but no signals on the bus:

I would say the CPU is dead. Maybe someone else has an idea here, but that is my conclusion.

I have a lot of spare key assigners here, because I replace them with my ModyPoly mod. I could probably send you one if you are willing to pay the postage..

Thanks I checked them out.

Nothing on pins 12-15, the rest listed show something (a voltage)

Thanks again
