Well my Illustrator Trial is just about to run out.

I think I might have gotten a little carried away with it, but here are the CP overlay and Side Art that I came up with. Comments are welcome.
First the CP.
Those little white holes on the top row of the overlay are for a spinner, 2 4-way joysticks, 1 converted flight stick. On the bottom row there are 2 8-way joysticks. The large white hole in the middle of the bottom row is a trackball.
This used to be a TMNT 4 player cabinet, although when I got it had been converted to an early version of Golden Tee Golf. That is why the control panel is so large.
