Quoted from Davi:Correct!
The ball trough design by Data East is not the most reliable mech in pinball. I have tried new microswitches, old Cherry switches, finetuned the angle - without stable result. I have also sanded the ball trough.
Then, I started to think about a non-contact based solution. There is a reason why Bally/Williams introduced opto boards, and the answer is not cost saving.
My goal was to create an opto board, without any modification of ball trough (no drilling): this means a transceiver and receiver in 1 board, 2 in 1. Therefore, the classic solution (infrared light interrupted by ball), doesn't work here.
No more waiting after ball drain, no more ball search due to clogging. I guess it works in GNR, Tommy, Last Action Hero, Tales from the Crypt, and WWFRR.
