This is some awesome engineering, and an equally as awesome result. Does anybody know if the author is going to put these boards on sale or what he does with his designs? I'd imagine from the look of the PCB (2 layer with no solder mask or silkscreen) that they're designed & printed with ExpressPCB - they look similar to a few I've done with them before. This really makes me want to start tinkering with older gaming systems.
