 ===== Introduction =====
-ZRC is derived from the [[builderpages:plasmo:zorc:zorc0|ZoRC]] experiment. The basic notion is that large RAM and fast serial upload enable a diskless CP/M SBC. However, just in case that idea didn't work out, ZRC has an optional compact flash interface. The targeted software for ZRC is ROMWBW
