Quoted from xsvtoys:I was thinking about this recently. What do you think about re-purposing the stuck coin return push button? If you are not going to use the coin mechs you don't need it anyway. You can pull that button out and replace it with something that could be wired into the coin switch. Then you would have an easy way to add credits, from the outside, without any significant mod to the cabinet or coin door. The original button could be saved and put back on if desired in the future.
This is a bit how ya doin since things didnt line up right, but i made the slug reject button add credits to a gottlieb system 1 game. I snuck some fish paper in there to isolate. As the slug reject button is pushed the metal bar comes down and pushes the top leaf into the bottom leaf. Been this way for years now and no problems besides people asking me how to add credits on Buck Rogers.
I would avoid drilling holes in the cabinet to add a switch. My Dolly Parton I am working on has a doorbell switch to the left of the cabinet. Looks like hell, but I will probably leave it since the rest of the game is a bit of a beater.
