PS/2 systems introduced a new specification for the keyboard and mouse interfaces, which are still in use today and are thus called "PS/2" interfaces. The PS/2 keyboard interface was electronically identical to the long-established AT interface, but the cable connector was changed from the 5-pin DIN connector to the smaller 6-pin mini-DIN interface. The same connector and a similar synchronous serial interface was used for the PS/2 mouse port. PS mean personal system.
