Maybe you didn't update the micro-desktop schematic as much as you
intended to when you changed the EOMA68 spec from 24-pin to 18-pin
RGB/TTL but in v1.7 you did at least connect only the 6 high bits of
each color to the D/A convertors.  The new pins are all connected to
useful sub-circuits on the micro-desktop board:  SPI (expansion
header), SD0 (SD slot), and PWRON (power switch).
