Red toggle at the top is power, it's lighted when the cab has power. The silver piece right below that is a key lock- on allows you to push the coin reject for credits, off the only way to get credits is insert coin.
THe red below that is a mini-momentary thats mapped to P or mouse button1.
You can almost see a black circle at the bottom of the clear part. THats the volume control. Theres a knob that extends out thru a hole in the plexi
The clear part itself is a scrap of the tinted plexi I used over my monitor. Without the flash it's almost opaque black, looks pretty slick
edit-

I need a aluminum/black knob, gonna raid some old stereos
