Page "Kempston Interface" Paragraph 2

The Kempston Interface, produced by Kempston Micro Electronics, was the generic name for any interface on Sinclair's ZX Spectrum series of computers that allowed joysticks complying with the de facto Atari 2600 standard to be used with the machine.

It was one of the most widely supported standards on the machine.

The interface itself would be attached to the computer's rear expansion port with a single joystick port on the front or top of the system.
