Namco System 12

The Namco System 12 is an arcade system board released by Namco in late 1996. In hardware, it is an upgrade from Sony's PlayStation-based System 11, the MIPS R3000A microprocessor is 50% faster, and the C76 sound processor is replaced by the H8/3002. Like the System 11, the System 12 used surface-mounted ROM chips, meaning the boards were unique to each game.^[1]
