From the project

Drop-in replacement for the Sega 837-10539 I/O board (Daytona USA twin, Model 2), built around an Arduino Mega 2560. KiCad 10, CC BY-NC-SA 4.0.

A drop-in replacement for the Sega 837-10539 I/O board of the Daytona USA twin cabinet (Sega Model 2), built around an Arduino Mega 2560. It lets an emulator drive the original cabinet: controls, lamps, meters, the original drive board (force feedback) and the original arcade monitor.

The idea is simple: pull the Sega I/O board out of the cabinet and put this one in its place. It has the same size, the same mounting holes and the same connector names, so the original harness plugs straight in. Nothing gets cut or rewired.
