AT motherboard, why no ps2 ports

[ka_mcginniis]

Just curious why AT motherboard have not ps2 ports for key board and mouse
what is typically used to accomadate mouse and keyboard.
What is the port that is on the board

basically because those boards were popular several years back when PS/2 was not a common option.

On those boards the Mouse used the Serial Port and the Keyboard used a propriety DIN socket.
