PC Keyboard Connected to PSP

An anonymous reader writes "A hardware engineer has managed to successfully connect a full-sized PC keyboard to the Sony PSP handheld. It looks as if the hardware modification was done with several different xlink cable connectors modified to interlink with each other. Obviously, the software side of things is not complete, but this is still a very interesting modification." The real question is what killer apps will come out of all this PSP hacking. There has to be more than just MAME emulation.
