We could obviously create a v1.8 schematic for the microdesktop and connect these EOMA nets to a header, if desired.
yes. damn. i think it's probably that i didn't update the micro-desktop schematic when i changed the EOMA68 spec from 24-pin to 18-pin RGB/TTL.
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).
