Closeup of action buttons wiring, plus smaller Coin and Exit buttons from Radio Shack. (I don't recommend using these types of small buttons -- I'm never going to use them again. I'll use regular concave arcade buttons for Coin, Pause, and Exit in the future.) Notice the latches on the left side of the picture. I yanked those highly ineffective "pinch clips" (you can still see the screw holes) and replaced them with simple brass latches to connect the panel to the cabinet. This turned out to be a bad idea too -- they were still too loose, and the panel would shimmy and wiggle when yanking the joystick around. I ended up having to scrap them and install steel L-brackets with thumb-screws instead.
