I ask you to contribute to the database by inputting the following details of your system to be found on the sticker at the rear of the PS2:
SCPH model number
Uxx - the first two digits of the Serial number
PTxx - the first two digits of the barcode number
Datecode 0x, 1x or 2x
# of screws in the upper rim of the Expansion bay (30001R)**
The name/version of any Messiah class modchip present
