Background
Beginning with the release of the original PlayStation in December 1994, Sony has gone on to develop many PlayStations and several versions of the PlayStation Portable (PSP).
Identification
Sony game consoles are usually easily identifiable, since the name is displayed right on the front of the unit. However, the hand-held PlayStation Portable line looks very similar to one another, with the exception of the PSP Go. If you're not sure which PSP you have, you'll have to remove the PSP's battery and look for the model number underneath.
