This interface allows you to connect a Kempston standard joystick to your ZX Spectrum computer (including Atari/Atari 2600 compatible). The board features an auxiliary micro-joystick with two buttons.

Note!
For proper operation, the device must be mounted on a universal I/O Port card – MUMIO dev. #00.

WHAT IS MUMIO?
MUMIO is the equivalent of Arduino peripherals, adapted for control from a ZX Spectrum computer. These can include sensors, displays, motors, servos, relays, joystick interfaces, clocks, UART, USB, I2C, SPI interfaces, and many, many more…

MUMIO devices are installed on an I/O card (dev. #00), connected to the ZX Spectrum’s edge connector.
