The expansion interface for the Model 100 was a z-80 based single
board computer with 780 disk controller and ?6845? (I believe)
CRTC.  It used a parallel 8-bit bus to communicate with the
80C85 in the M100.  If someone got the schematic to the board,
figured out the addressing scheme, wrote a new driver, and added
a parallel keyboard in place of the M100, it would be a standalone
computer.  Anyone want to write the CP/M Bios?
