Player 2 Flap isn't working on my Joust. I put the game in switch test, took off the connectors on the Interface board and jumpered ground to the player 2 flap pin. Nothing. I got my logic probe and checked for a pluse on IC7 pin 7 and got a low pulse when closing the flap switch. I swapped out the interface board with my Robotron and still not working. I guess the problem is on the CPU? I don't understand the schematics enough to locate the problem any further. Please help, thanks.
