"The removal of the parallel port was probably partly because no official add-on had ever been released for it, and partly because it was being used to connect cheat cartridges that could be used to defeat the regional lockouts and copy protection." from here I guess at the time Sony had some ides of using it for expansion and different controllers but later abandoned the plan. Hope this helps...

"This port is used for connecting 2 playstations together. Used for playing games with other people using 2 tvs

Used for Action Replays, GameSharks, VCD adapters, the long-awaited PSIO adapter, and Game Boy (some idiot's probably gonna "correct" me by saying "its not game boy its game boi") Adapters. The only time that is was actually used by Sony was for the debug units' PC parallel port (Or SCSI) adapter.
