It's a big round port about 2cm in diameter that AT style motherboards use for keyboard interface. Not sure how many pins offhand.

It's an older port that isn't used in any newer computers, which use the ATX form-factor, and have a keyboard port thats about 8mm in diamter with 8 pins.

Yeah there is a PS/2 or an AT. The AT is 5 pin (Pretty sure /forum/smile.gif) and the PS/2 is half the size of the AT. PS/2 can also be used for a mouse.
