Kim! you guys are tenacious and detailed! that ChCoin Riviera problem I was having (BCU stepper would advance, but dropped back slightly before advancing) turns out that the bracket on the reset coil had broken, so the coil wasnt supported when it was firing. (Kudos to Mark@ FWPinball for helping identify that)! Ive got some homework ahead of me to get a lot of clean up accomplished, but Im looking forward to getting everything in order. Appreciate what you achieve and share so generously!

Grreat tip!

Thanks Kim, would this be a fix for an occasionally sticking score motor too?
