CPU UPGRADE FOR SCI PROPHET 5 REV2
Latest upgrades: 2014/07/10: Prototype board ready. The project for next odd years has finally started.
From the beginning it was quite clear to me to do two versions of the upgrade: One for stock P5 and one with new CPU board having MIDI and other goodies to get around the limits of original hardware. The new CPU board has more RAM and ROM for running more code and having more patch storage, midi in / out, etc.
