The Big Board (1980) and Big Board II (198 … The Big Board (1980) and Big Board II (1982) were Z80 based single-board computers designed by Jim Ferguson. They provided a complete CP/M compatible computer system on a single printed circuit board, including CPU, memory, disk drive interface, keyboard and video monitor interface. The printed circuit board was sized to match the Shugart 801 or 851 floppy drive. This allowed attachment to up to two 8 inch or 5 1/4 inch floppy disk drives . The Big Board II added a SASI interface which could be used to drive hard drives, enhancements to system speed (4 MHz vs. 2.5 MHz) and enhancements to the terminal interface. One version of the Big Board was used in the Xerox 820.f the Big Board was used in the Xerox 820.
