I had one of those, "It seemed like a good idea at the time" moments and brought home an old empty cabinet to convert into a Mame machine.

It wasn't until I got it home into the garage that I realized just how much work it'll take to get it into shape. The cabinet is rock solid, but cosmetically it has seen better days. The control panel tells me it spent some part of its life as a NeoGeo, but closer inspection leads me to believe this was a generic cabinet or a kit.
The Marquee brackets are a little bent but still usable, what's with the incandescent bulb?

When I first looked at the cabinet I figured I could replace the broken t-molding, but it looks like the groove was routed left of center. I think they wanted to use half inch t-molding on 5/8". The funny thing is, it is left of center on both sides.

One of the first things I need to do is patch the t-molding groove and cut a new one.
There is a lot of extra "Security Iron" on this cabinet, I'm guessing it wasn't in place at the world's nicest location. There were two heavy duty brackets bolting the Control Panel closed.

And the Coin Door had its own Vault Door.

Something is very odd about this control panel. There are holes for the classic fighting game six button layout as well as joystick holes. However, new holes for the NeoGeo button layout were cut as well as slightly different joystick holes. The NeoGeo control panel overlay was stuck on over it and the plexi on top of that disguised the old holes.

Remnants of the wiring harness are visible inside. It is a Jamma connector, but there are also a number of severed wires and other wires spliced together with electrical tape. It looks like an old blue button is still wired to the harness, but wasn't needed for the NeoGeo layout.

Now, where to start...
