Today I powered up the Mame console.
DO NOT ATTEMPT THIS
The wiring is dodgy and there is an exposed crt monitor in there with loose electronics.
Currently its using a pentium III
I am looking into upgrading it to a Pi and LCD.
Michael Sharman has done a great job wiring a keyboard controller to all the buttons and installing a menu driven by joystick, so I hope to copy that software and use on the pi.
