DEM-3000

The abbrevation "DEM" most probably corresponds to Developer Engineering Model and was used for Prototypes of Vita Development Kits with the model/generation identifier 3000. (Just like DEM-1000 was for PlayStation Portable Development Prototypes!) Why they skipped the 2000, especially since the Vita was even internally named PSP2, remains unknown though.

The tailing letters like Gxx/Hxx/Kxx/Lxx etc, describe the revision followed by the 3rd & 4th digit of the serial number. The only exception makes the DEM-3000JEC which exists multiple times alongside each model after the Slider Design. Its generation can be identified by the seventh serial digit.

Example: DEM-3000H84
