Bob,
You seem like the Z80 master. Regarding your comment about the P600 upgrade. I think rather than have a few wires added to a teensy board, that someone should just make a drop in replacement board for the Z80 (could be otherwise the same or nearly so to the teensy). I don't know if it would be better for developers to write code from scratch for that CPU (is it an ARM or PIC?), or if Z80 emulation is possible?
There are so many synths, especially from the US, that used Z80 The 8051 has nice upgraded versions with so much more speed, memory etc.
