RE: free play coin up circuit.

Don't know if this is applicable, but on most games I used to own, I would
take out the coin mech, and put a microswitch in so it was activated by the
coin return mechanism, and wire that to the coin input. Worked especially
well on Bally style doors like Pac-Man

It does; however, that feature can be disabled by jumper.

John doesn't yours add a credit on power up? If so that would change the
attract mode on some games to be a static waiting for p1 or p2 screen.

Kevin,

I designed a 555 timer circuit a couple of months ago:

I used it on the Captain's chair for Texas Pinball Fest this March.

It's open source. I imagine it could be adapted to credit two players. In
"volume" the components should be cheaper.

Thanks for the link but id rather not spend the amount of money it would
take to get 10 of those. Id rather build something.

There are also people that provide rom hacks for those games that don't have
freeplay.

Also, some games don't even have start buttons (pole position, eliminator
4player), so either a romhack or separate physical switch is needed.

Sorry for those on both lists if you get this twice.

I'm wondering if anyone has built a coin up circuit for games that don't
have free play.

So when P1 is pressed it adds a coin and starts a game.

When P2 is press it adds two coins and starts a game.

I'm not much of a designer of circuits, and I figure there is probably some
timing that needs to be worked out between coin pulses and 1up.

Thanks,

Kevin
