PlayStation PU-22 8MB RAM daughterboard
This daughterboard replaces the RAM IC on PU-22 PlayStation motherboards, allowing the user to expand the RAM of the console from 2MB to 8MB, same as a development kit.
The modification requires this board printed as a flexible PCB, assembled, the original RAM removed and replaced with the board, plus two additional addresses taken from the CPU via jumper wire.
I repeat, this board must be printed as a flexible PCB!!!
