Atari Xevious to JAMMA Adapter

Description

After licensing Dig Dug from Namco, Atari licensed Xevious, another Namco classic for distribution outside of Japan. As with Dig Dug, they also completely redesigned Namco’s boards while still utilizing Namco’s custom chipset.

The Atari version of Xevious has a unique pinout. The pinout is not compatible with the Namco version of the game, or other Atari games licensed from Namco.
