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.

(Despite my ASCII art, the main boards are actually all the same size.)
