    Fanuc System 15

    2014-01-04 Skeleton driver.

    This is a circa-1990 CNC machine with a very custom GUI, made of a
    bunch of boards plugged into a passive backplane.

    Possible boards include:
    A16B-2200-0020/04B : Base 2 Board (contains 12 MHz 68020 "CNC CPU" and 1 or 2 MB of DRAM)
    A16B-2200-0090/07A : Digital Servo 4-Axis Controller Board (no ROMs on this board)
    A16B-2200-0121/06C : Base 0 Board (1 ROM location but position is empty. -0120 has 6081 001A)

    A16B-2200-0131/11B : Base 1 Board (15 ROMs on this board, 4040, 9030, AB02)
        See detailed layout and description below.

    A16B-2200-0150/03A : Conversational Board (4 ROMs on this board, 5A00, probably for Mill)
    or
    A16B-2200-0150/03A : Conversational Board (4 ROMs on this board, 5C30. 5C for 2 axis Lathe)

        MB81464-12 (x12)
        20MHz OSC
        3 EPROMs. 6082 is common to both mills and lathes.
        600A is a known EPROM version required for lathes with FAPT conversational graphics.
        600B is unknown. Possibly for mills with FAPT.

    A20B-1003-0230/09C : Motherboard (dumb backplane, contains only slots)
    A20B-1003-0500/01A : Additional Graphic Board for 15TTF only (for TT, connects to A16B-2200-0160 Board. No info on this PCB)

    Notes:
          The A16B-1600-0280/02A board contains only 12 DIP32 sockets and some logic and
          bolts to the back of the BASE 1 board. The board extends the boot software memory
          storage space if additional EPROMS are required. Not all sockets are populated.
          Connector CNM1 joins with a 40 pin flat cable to the BASE 1 board connector CNM1
          IC locations are not printed on this board. Only the ROM # is printed at each
          socket location.
