Quickshot Trackball

The Quickshot Trackball is an unlicensed controller designed for a number of gaming consoles, including the Commodore 64, Atari computer line, the Sega Master System and the Nintendo Entertainment System. The joystick is often confused with a trackball due to the similar shape, however its design is not a complete sphere, but a large dome attached to a switching mechanism that slides forward, backward, left, and right. The Quickshot can be changed from right to left hand use via a slider switch on the side of the unit.
