Lew,
Here is one from CP Sketcher. The trackball is a Beston 3". The two buttons in the upper right will be the player 1 & 2 start buttons. I don't know if I want to put the NavaGemCDR on the center of the front or the bezel. near the start buttons. I did another 2 hours of work on the artwork tonight while the girls had their voice lessons so below is the current version. This is closer to what I was thinking about but you are welcome to start from the first version and work you way up to something like this. It night not be a bad idea at that. I used a lot of covering blocks and copy/paste to extend the starburst.
TTFN and THANKS,
Kaytrim
edit... Since you know the cab that I am working on I got exact measurements of the cp for you. from the top edge to the front hinge is 10.25" From the top edge to the joint between the top and front is 7". The CP is 16" wide. I hope that helps.
