2 AristotlePagaltzis 1 [PS/2] was originally the name of a new range of [IBM] [PC]s which were not [IBM] [PC] compatible. [IBM] tried to reclaim the [PC] market from the clones with this move. Instead, it cost them whatever dominance they had left. Nowadays the term is used to refer to the compact connection ports for keyboards and mice introduced with the [IBM] [PS/2] line of computers, as opposed to the much larger XT/AT ports for keyboards and the serial connectors for mice. Now largely replaced by [USB] peripherals.
