I've been wanting to do this since Mame came out around 1997, so roughly 16 years later, I finally picked up my empty cab. It's a 1982 dated Robotron 2084. came with the sides laminated in a red color formica. Also came with the original Coin Mech Inc. coin door and mechanism, and front smoked glass. It diid not have any control panel attached, so I was going to have to build my own.
I opted to remove the laminate since it made the sides a bit thicker and sticks out just past the existing T-molding.
Here is a drawing I made to scale in sketchup of the cab and what I am doing for a control panel.
I'll post more pics later when I get them off my phone...
