This is a project started back when Killer Cabs was around. The purpose was to unify all components needed to play MAME emulated games on a standard JAMMA cabinet. The controls and I/Os all pipe though the one PCB to the integrated JAMMA card edge and the PC's hard disk and motherboard screw directly to the board for convenience.
The boards are no longer available but this page serves as a way of troubleshooting problems owners may have.
This page will be updated soon.
