Wikipedia agrees:

	PS/2 systems introduced a new specification for the keyboard and
	mouse interfaces, which are still in use today and are also called
	"PS/2." 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, as was the PS/2 mouse interface.

It's really too bad that IBM didn't license PS/2 architecture, or at
least MCA, to everyone.  It took the rest of the PC world about 7 hears
or longer to fully catch up to what MCA busses and motherboards could
do.
