==== Amiga CD32 gamepad ====
The Amiga CD32 games console is based on regular Amiga hardware with two controller ports. The gamepad has a [[D-pad]] and seven buttons: Blue, Red, Yellow, Green, Right Front, Left Front and Pause. It would of course work in other Amigas given software support.

Games not specifically made for the CD32 game-pad (such as ports) would leave pin 5 high which makes Red work as Fire, and Blue as the second button.
When pin 5 is low, the button state could be read serially on pin 9 from a 74LS165N shift register using pin 6 as a clock. The register is reset by setting pin 5 high again.
