New to forum. New to Pinball. I stumbled on a Black Hole machine and now i'm learning on an early system 80. Recently replaced the sound prom on sound board and got most of the speech to work. Tested per Clay's website and guessed problem to be A1-J4/ A3-J1 connection. Rebuilt it and still didn't work so bought new Docent connector. Now machine won't start game and won't accept coins. I'm at a loss now and getting frustrated. Can anyone help me? Thanks in advance.

Find a pinball machine website. We seem to be getting a lot more of these but I'm afraid it's outside of our expertise. Sorry chap
