Turbotronic is ajoystick marketed byCamerica in the late 1980s. The joystick has twoconnectors: One with sevenpins for theNintendo Entertainment System, and one with nine pins for severalAtari andCommodorehome computers andgame consoles, as well as theMaster System.[1]
The Turbotronic closely resembles theNES Advantage, a joystick released byNintendo of America in 1987. In 1988, Camerica releasedFreedom Stick, awireless,consumer IR version of Turbotronic exclusively for the Nintendo Entertainment System (NES).[1] Nintendo brought legal action against Camerica because of the products' similarity to the NES Advantage.
Camerica later redesigned Freedom Stick with an unorthodox triangular base intended for both right- and left-handed players, and called the productSupersonic the Joystick. The bottom of the joystick's base is fitted withsuction cups to stabilize it on a tabletop.
Freedom Stick and Supersonic the Joystick were among the firstgame controllers to communicate viainfrared beam. They were contemporaneous withBroderbund'sU-Force, a game controller that made innovative use of consumer IR technology.
