Yamaha CS80

David, just curious, what's the problem with the MIDIboard?  I have a V3 MIDIboard that went haywire.  After a short warm up the display "strobes" and the instrument spews out MIDI data commensurate with the strobing.  It's got the short logic board with daughter card.  I tried reseating chips and ribbon connectors.  Maybe one of the EEPROM's has failed.

I bought a V2 MIDIboard a few weeks ago.  It works great, and I can't tell any difference between the two.  I never used the arpeggiator on the V3 anyway.  And this V2 revision supports sysex.  Neither board has the Suzuki action, so don't know what I'm missing there.  I had thought about upgrading the V2 with the V3's EEPROM's, but everything is working so I kinda don't want to mess with it.

Hope you get yours working.
