The keyboard does not use a QWERTY style layout and has special keys oriented towards ticket sales. A keyswitch on the keyboard has OFF, ON and MGT (management) positions to secure the terminal against unauthorized ticket sales. The cable connecting the keyboard to the terminal uses an 8-bit parallel connection for key codes and a 2-bit parallel connection for the state of the 3-position key switch, as well as power, ground and control signals.
