    Notes:
        1) Facing the CPU board, with the two large IDC connectors at
           the top of the board, and the large and small IDC
           connectors at the bottom, DIP switch #1 is upper right DIP
           switch, DIP switch #2 is the DIP switch to the right of it.

        2) Facing the Sound board, with the IDC connector at the
           bottom of the board, DIP switch #3 (4 bank) can be seen.
