Working with Gottlieb EMs: Fixing Scoring Problems & Score Reels

I had a chance to spend some time with a 70s era Gottlieb EM machine I recently picked up. This game came to me in non-working condition, mostly complete. For the complete video series with the early “first look” footage see this article.

In this series I spend most of my time diagnosing issues that are relating to the score reels.  I also take some time cleaning various contacts and relays which end up solving a variety of problems from games that never end to problems properly scoring shots and bonuses.   I hope you enjoy as I dive into this game getting it back to playing condition and learning along the way.
