The '''JY-1''', '''JY-2''' and '''JY3''' are the original joysticks [[Digital Joysticks]] from [[Amstrad]] for the Amstrad CPC computers.
In order to push sales of Amstrad's own joysticks, Amstrad designed the CPC with only one joystick port which had two different ground levels. The idea was to sell one joystick which forwarded the second ground signal to a built-in joystick port, to which the second joystick could be connected.
