Controller Port

This connector is only found on the Intellivision II and Sears Super Video Arcade, as they are the only Intellivision consoles with removable controllers. All controller pins except for GND are connected to the data input pins on the AY-3-8914 sound chip, and each direction and button shorts a different combination of these pins to GND, which are detailed in the matrix below.

Note: Female is connector at the console. Male is connector at the controller. Diagram pictured is of the connector at the controller end.
