Allows you to connect and play your Atari Liberator PCB to a JAMMA cab or supergun.

Liberator was released by Atari in 1982. Game concept is the reverse of Missile Command, where instead of defending cities and bases, you attack them from above. Liberator had some interesting pseudo 3D effects and was graphically quite advanced for the time, but the gameplay is quite simplistic and probably one of the main reasons why Lberator ended up being a marketing dissapointment. Production numbers were less than a thousand units. 

Like Missile Command, this game uses a trackball, but now only 2 buttons are used, one for missiles, and one for shields. This adapter can however utilize a standard JAMMA joystick setup with at least 2 fire buttons, using a built-in microcontroller for joystick to trackball emulation.

Like many Atari games from this period, Liberator has a unique pinout and is the only game that be converted with this adapter.
