Ok, ive been messing with this area 51 longer than i would like. I could not get a gun to work aon it, only got flashes on the screen. Ive messed around with enough and finally got it to resgister on player one side. But gun 2 will not do anythin except flash on the screen. Ive swapped the wiring around and both guns will work on gun 1. But both will only flash on gun 2. Ive replaced the entire wiring for gun 2 as well with no help

Any ideas what would cause gun 2 to not register

thanks

Ok, this is from memory (couple of years ago at least). Near the connector for the gun on the pcb, you will see some very small (because they are surface mount) 7404 chips. Those chips will go bad causing that input to not work. So at this point, chances are likely you need to have some SMD work done to replace the chips. The good thing is the chips are super cheap, the bad thing is you need someone to do the surface mount soldering.
 
I saw these crop up on ebay actually. just run a search for Area 51 in the arcade collecting section, you'll see them.

punt if the seller has less than like 99% feedback however. not sure where the hell they get these things from.
