Arcade board.
Namco System 22 (ナムコシステム22?) was an arcade board manufactured by Namco and Evans & Sutherland, and was first used in 1992; it is the company's thirteenth arcade board, and is the successor to the Namco System 21 board.
The hardware supported transparency effects, depth cueing, Gouraud shading and texture mapping. A variant of the board, Super System 22, was first used in 1995; this board featured higher polygonal rates and added graphical effects. The final game to use the hardware was Prop Cycle in 1996, and the board would later be retired after five years of service.
