@patrickl:  Thank you very much 

  Building these is a stress reliever for me from my job.  As far as the miniature ones go, I was thinking of doing a bunch with different themes (Asteroids, Defender, etc.)  I thought it would look cool.   

@CthulhuLuke:  That's because they are!  I picked up a cheap 'Tournament Ready' control Panel for a game system I didn't have, and used the buttons and joystick out of it.  (The joystick is used in a different machine).  I liked how they were labeled LT and RT (for the Asteroids/Deluxe/Space Duel/Ripoff/Space Invaders, etc. setup) and the 'A' and 'B' buttons (for the Nintendo Vs. setup).  The layout I have on there fits so many different games (obviously except the fighting ones), that's the one I've been using.  The only one I have an issue with is Defender and the placement of the 'Reverse' button.
