hmmm, I don't have pics anymore. We actually shipped the bartop off to someone, and it got destroyed by fedex along the way somewhere (it played great while we had it here though, and luckily we had opted to purchase insurance on the bartop).
If I recall, it wasn't quite as easy to get going as the Jakks board was (the Jakks board is all labeled nicely and is very well documented here on these boards), but it wasn't that difficult either. Once you get it open, you can see what wires are going where and then just replace the wires with ones going to your own controls (if you are swapping out controls).
Getting it to swap between this board and the Jakks Pac-Man board was a little trickier too if I remember. We had to go down to radio shack and get some parts to make the whole thing work, and there was a lot of trial an error, and I think for some reason, it ended up working only we hooked it up backwards to what we thought would logically work (but that is probably due to our stupidity and not the boards

).
I personally liked the space invaders on that joystick, but I think I remember someone saying that it wasn't an emulated version of the arcade, but of some other 80's system or something, so it wasn't the best deal. I'm pretty sure I read that here on these boards, but I could be wrong.
