There is nothing special you need to do, except to make sure the switch on the coin mechanism is set to the normally closed position. It runs with new coin mechs also. The top two mounting holes match the original board mounting, but you might need to drill the other two into the table to use them as well. When the table powers up, the board instantly sets the counter displays to "0", resets all the logic states, and is ready for the coin. When the board receives the pulse from the coin mech, the table starts up.
Each time the counter scores, there is about a 1 second delay before it can count again, making it impossible to accidentally double count (if the microswitches on the table have bad contacts for example). This board will run both type tables with either microswitches or opto-couplers. It replaces both types of board shown in two of the photos.The counters continue to score until the first one gets to "7", then the table turns off, and the score is held, and cannot be incremented further. When the next game starts, the counters reset again to "0". There is a 7 minute timer built in so that if the time reaches 7 minutes, the table turns off and the game comes to an end, and it waits for the next game to start.
Any special other functions that used to be programable in the original board, are not programable in this replacement. The display plug plugs into my board the same way around as on the original board, but mine has no locking connector to prevent it accidentally being put on backwards, so you need to be sure to plug it in the right way around, the same orientation as originally.The original header sockets seem to be obsolete. I couldn't find any. I can have more boards available, but they are hand made so it can take a couple of weeks to have more made. I personally make the boards myself, from design to finished. I can answer any questions you might have.
I guarantee the boards work.
