This interface allows you to plug any retro one or two button joystick with standard DB9 Atari wiring into a PC or emulation hardware such as Raspberry Pi or similar.
It was designed with the A500 mini and The Spectrum in mind and is unique in that the interface features separate buttons for the Menu and Home screens of these consoles. These buttons also work with other systems as Start/Select/coin etc.
The interface is based on the RP2040CE project and as such is updatable and configurable on a PC or laptop via a web browser.
This device comes already set up so just plug in and play.
If you do need to access the menu system to reconfigure or update, simply hold down the HOME button on the adapter while plugging the device into a USB port on your PC/laptop then open this webpage http://192.168.7.1/
