Turbo Touch 360
From Wikipedia, the free encyclopedia
The Turbo Touch 360 was a series of aftermarket third-party controllers made by Triax for the Nintendo Entertainment System, Super Nintendo Entertainment System, and Sega Genesis. What separated them from other controllers on the market was the fact that instead of a D-pad, they had a touch-sensitive panel, much like the touchpad on a modern notebook computer. The idea was to reduce repetitive strain injury to the player.
Other than the touchpad, the controllers had a standard set of features for controllers of the time, with turbo support.
