This is a Joystick Adaptor for the Exelvision EXL 100 computer. This will take the input from an Atari style joystick and convert it to the correct Infrared pulses. It also features the number pad that is present on the original Joysticks.

I decided to make it when I received an EXL 100 computer without the bundled joysticks, these are tricky to get hold of so this is a good alternative.
