Re: free play coin up circuit.

For a lot of games, all you have to do is add a wire from the coin switch to the player start button. The first press adds a credit, the next adds another credit and starts a game. If there are two coin switch inputs, wire one to P1 and wire the other to P2. This is how my home-use-only Sega Pengo was wired from the factory to hardwire it for freeplay.

Some people like to add a leaf or push-button switch behind a coin reject button such that pressing the reject button adds credits. This elminates drilling a hole for an additional button.

  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
