So as you may have figured out, I have an arcade cabinet in my living room. However, there was an issue with the control panel so I need to get another one cut, this time out of 3/4" plywood rather than the melamine.
Without a control panel to wire I was still able to test the other components. The sound system that I tore apart, ripped the PCB out of, cut wires off of, glued the face plate to, and then screwed to the back of the cab actually does work. As does the monitor and computer. I played a couple of games tonight using a regular PC keyboard. Not quite the same experience though...
I still have the ocassional seemingly random focus issue. Sometimes when exiting out of an arcade game and returning to the front end the front end does not get focus back. This means you must press alt-tab or click the mouse to restore focus. Not exactly easy to do on a control panel without a mouse or a tab key...
