The Namco System 21 "Polygonizer" is an arcade system board unveiled by Namco in 1988 with the game Winning Run. It was the first arcade board specifically designed for 3D polygon processing. The hardware went through significant evolution throughout its lifespan until the last games, Cyber Sled (1993) and Attack of the Zolgear (1994), were released. It was preceded by the Namco System 2 in 1987 and succeeded by the Namco System 22 in 1993.

System 21 Specifications

The System 21 consists of four PCB's housed in a metal crate, including a main CPU board and a GPU graphics card.
