    Burroughs EF315-I220 bank teller terminal

    These 8-bit terminals were used by banks before they were displaced
    by cheap PCs.  There's an external customer PIN pad with its own
    ROMs, and a keyboard for the teller.  Unfortunately the teller
    keyboard was missing from the unit that was dumped.  These terminals
    contain a hardware DES chip which was a controlled item due to trade
    restrictions on encryption technology.

    The main system consists of three large boards in a stack: D8302
    (I/O board), A8301 (memory board), and C8209 (CPU board).

    The MICR/OCR unit appears to be an off-the-shelf unit built by
    Recognition Equipment and has a single board mounted in the top
    case.  Its main CPU is a MOSTEK MK3870/42 which has an undumped
    4032-byte internal mask ROM.

    Onboard peripherals:
    - Small "green-screen" CRT display mounted on an adjustable "stalk"
    - Thermal printer
    - Card swipe
    - MICR/OCR for reading cheque numbers (swiped the same way as cards)

    Rear panel connectors:
    - J1 (25-pin D-sub male)
    - J2 (25-pin D-sub male)
    - J3 (7-pin MIL-C-5015 connector)
    - J4 (5-pin 180-degree DIN female)
    - J5 (25-pin D-sub male)
    - J6 (15-pin D-sub female)

    TODO:
    - Check designation of MICR board.
    - Does U2 on the MICR board exist?  I can't find it on the overlay.
    - Finish parts list and ASCII art for CPU board.
    - Do IC50 and IC56 on the I/O board exist?  I can't find them on the overlay.
    - Work out how clocks are derived.
    - Hook everything up.
    - Emulate DES engine.
    - Photograph the guts of the PIN pad and check ROM labels.
    - Find way to dump MK3870/42 in MICR reader.
