An Intellivision has a left and a right hand controller. Each controller has a disc controller, a 12-number keypad, and 4 "action" buttons (2 on the left side and 2 on the right side). The disc controller can record any of 16 different locations when pressed. It is the grandfather of the D-Pad used in 21st Century consoles, except those tend to only have 8 positions.
