From the project
MiSTer user port MIDI output and input PCB
This repository contains the KiCAD project files for a custom MIDI Interface Board, designed to connect to the User IO port of the MiSTer FPGA. It enables MIDI input and output functionality for cores that support MIDI, including the Atari ST, X68000, PC, and Minimig.
