Controller Pinout[1]

Notes: Male is connector at the controller. Female is connector at the console. Diagram pictured is of the connector at the controller end. The Jaguar controller interface acts like a keyboard matrix, scanning across the column pins and reading the row pin output to determine button pressed. Pins 5 and 15 are the analog pins which only function on boards with U16 (ADC0844) present.

Cartridge Pinout[2]

Note: Side B faces towards the front of the console (towards the controller ports) and side A faces towards the rear of the console (towards the AV connector). Pins A13, A14, B13 and B14 physically do not exist, and are blocked off to act as a key for cartridges.
