Hey Gang, I am putting my 6 PCB jamma cab back together (got a BEAUTIFUL 38" Max Force Showcase over the weekend)

I have a set of Namco Recoil Guns, the solenoids are fried but I have taken the mech apart and using spacers I could easily fit a different solenoid in that runs on whatever voltage/amperage I want to feed it.

At first, I want to rig the trigger pull to fire the solenoid every time for every game. Then as I learn I want to get the games that have a recoil built in working off of their correct circuits (i.e. point blank)

Either way, I think this board:
https://ksarcade.net/rottendog-pop-bumper-driver-for-gottlieb-system-80-pbb080.html
Is going to get me real close to my goal.

BUT does anyone what the pins on J1 are for?

and what are the odds I'd be mostly finished if I hook up a power supply and replace the "button switch" on the board with an opto-isolator wired to close on the game's trigger circuit (jamma button circuit).


Thanks Gang!
