Abstract: A digital joystock is interfaced to a video game by utilizing diodes for isolation and providing means for strobing the digital joystick. In this manner, the number of conductors required in the cable coupling the digital joystick to the video game circuitry is significantly reduced. In one embodiment, a matrix-type keyboard is included in the remote control unit without adding a significant number of additional conductors. Furthermore, the multiplexer ordinarily required to couple the conductors from the digital joystick and the matrix keyboard is eliminated by this technique.
