The Kawai & Teisco Analog Synths Group

When you replaced the components did you also fix all the eroded traces on the PCB around them? Also, it's very important when you do this that you clean that whole area of the PCB thoroughly, or it will continue to erode over time.

After doing that I could get the interface to sort of do something, but I still couldn't get it to respond to the "panel check" command. I've got a ROM chip coming from Kawai because it was cheap enough, I'm just waiting for it to come in the mail. I'll let you know if that fixes it.
