Going through a stash of parts I stumbled upon these.I know they work in Q Bert and possibly other Gottlieb / mylstar games. Gonna mount one off the board to see if it still works
Honestly not sure, bought a bunch of drawers of IC's and other parts and they were in one of the drawers. I am guessing pretty old but we'll see if they work or not. I wired one outside of my qbert, the worst it could do is not work.
