[1] The Turbotronic closely resembles the NES Advantage, a joystick released by Nintendo of America in 1987.
In 1988, Camerica released Freedom Stick, a wireless, 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 product Supersonic the Joystick.
They were contemporaneous with Broderbund's U-Force, a game controller that made innovative use of consumer IR technology.
