XT1 = 16.000 MHz
DP1 = 8 dipswitches
CN4 = Speaker
CN9 = RS232
CN8 = Power Out
CN6 = Magnetic stripe reader
CN2 = Display (dot-matrix, 2 lines x 16 characters, 5x7 each character)
CN7 = Keypad
Status:
- Shows current date and time, then presumably waits for keypad input
- Needs currently unimplemented V25 features (serial etc.)
