The Namco System 11[a] is a 32-bit arcade system board developed jointly by Namco and Sony Computer Entertainment. Released in December 1994, it is a successor to the Namco System 22, the company's first 3D arcade system. The System 11 is directly based on the PlayStation, Sony's first home video game console, using a 512 KB operating system and several custom processors. An upgraded version of the System 11, the Namco System 12[b], was released in 1996 and features a faster processing power. Tekken was the first game to use the System 11.


Although the System 11 was technically inferior to Sega's Model 2 arcade board, its lower price made it an attractive prospect for smaller arcades.[1][2] According to the June 1995 issue of Edge:

Namco took a significant risk in basing its Tekken coin-op on raw PlayStation hardware, considering that it would be competing directly with Sega's Model 2-powered Virtua Fighter 2 ... For once, a home system can boast an identical conversion of a cutting-edge coin-op ... Namco's research section managing director, Shegeichi Nakamura ... explains: "When Sony came along we decided to go for a low-cost system—in short, we've left the big arcade stores to Sega and VF2 and Tekken has been sold to smaller arcade centres" ... Namco has a further four titles planned for System 11, all of which are likely to make the jump to the PlayStation.[1]
