no i dont.  i didnt really create a layout or plans or anything, i just built it.  i know that sounds weird, but i guess everybody has to start somewhere.  although i was inspired by TalkingOctopus's cab and cp.   if you like my 4 player setup, you will definitely like his.  its on an upright cab, so the joysticks and players are squeezed in a little more than mine.  dont have a link, but google for "talking octopus mame" and youll probably find it.
