I found a parallel I/O port at the rear of the PSone. What is it used for?

"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...
