Thanks for the feedback guys. markvp, you did a hell of a job on your 4 player cp. You gave me alot of inspiration. Anyway, It is big, I agree, but I want it as comfortable as possible for players 3 & 4. Once I get everything layed out I will see if I can make it a bit smaller. Thanks for the suggestions. I will make most if not all the changes.
Now I was toying around with the idea of putting an 8 port USB hub in the CP so I would only have 2 wires to connect when switching CPs. I know the controllers will have a USB interface, not sure about the spinner and trackball, but I assume they can be hooked up via USB as well. The only thing I would need to worry about is fitting all the interfaces in the CP, hence the large CP. Decisions, decisions.
