Recently acquired a 68-channel logic analyzer with inverse assembly capability. I need to make an adapter board for the 68k though... the ones online are either for the PGA version or very expensive.
I've started to go through and see what the other address areas are to make a list (MIDI IN/OUT, foot pedal, LCD). Curious about the backlight timer code too.
I noticed in the VS owners manual that mode 4 aftertouch messages are treated like the mod wheel. Wonder if there is enough room in the code to make it either poly-AT or poly-AT-->chan split compatible. Maybe I can drop some of the diagnostic code like they did :).
