A donation to the museum, this was one of the joysticks that were bundled with the Amstrad CPC464. It has the built in joystick port for two players as the CPC only had one port.
Widely regarded as one of the worst joysticks ever created which led to the development of Y leads so other joysticks could be used instead
The port used two common pins to read the shared inputs from both joysticks together
And unfortunately the rubber feet are missing from this one which somehow makes it worse
