The original IBM PC had a 5-pin DIN connector. The IBM PC AT kept this connector for its keyboard, but the signal was changed to a newer bi-directional protocol to support the keyboard LEDs. Later on, IBM released its PS/2 line of computers, but this time they kept the protocol and changed the connector to a 6-pin Mini-DIN form. The end result is that PC AT keyboards can be plugged into any PS/2 port using the appropriate adapter.
