Page "Namco System 22" Paragraph 1

The Namco System 22 is the successor to the Namco System 21 arcade system board co-designed with the assistance of graphics & simulation experts Evans & Sutherland.

It was first released in 1993 with the game Ridge Racer.

It was essentially a continuation of the System 21 hardware design, where the main CPU provides a scene description to a bank of DSP chips which perform all necessary 3D calculations.

Additional graphical improvements included texture mapping, Gouraud shading, transparency effects, and depth cueing thanks to the Evans & Sutherland ' TR3 ' chip / chipset,
