After doing a quick search on Pinside and Google Groups, I did not see a posting about this issue. Knocker goes off twice with a slight delay between the two. Numbers are correct, credit wheel rings up both. Logis on the schematic seems pretty straight forward. Four ways to award credits-coins, high score, hole special, and match. I haven't spent a ton of time looking at all these circuits, figured I'd throw it out to the group if someone has encountered this before. (I never have!)
TIA
