SYSTEM22 POINT ROM PCB

The Namco System 22 is the successor to the Namco System 21 arcade system board. It debuted in 1992 with Sim Drive in Japan,^[1] followed by a worldwide debut in 1993 with Ridge Racer.

The System 22 was designed by Namco with assistance from graphics & simulation company Evans & Sutherland. Graphical features include texture mapping, Gouraud shading, transparency effects, and depth cueing, thanks to the Evans & Sutherland 'TR3' chip/chipset, which stands for: Texture Mapping, Real-Time, Real-Visual, Rendering System. The main CPU provides a scene description to the TR3 graphics processing unit and a bank of DSP chips which perform 3D calculations.

A variant of the system, called the Super System 22, was released in 1995. The hardware was largely similar to the System 22, but with a slightly higher polygon rate and more special effects possible.
