The ball gate switch is a very important switch, indeed! It tells the bingo with a time tree that it should throw a trip relay based on the position of the timer unit. Without the trips tripping, the timer will no longer advance, and you will have crazy gameplay issues, including issues with registering replays, locking you out of various timetree-driven features, etc.
Bally and United were both manufacturing bingo pinballs in the 1950s. Since starting this show, I've been increasingly interested in the differences between the two manufacturer's machines. United's mechanics and circuits are engineered differently than the Bally ones, and I like 'em both!
Another deep tech episode - how to remove the unit (could be anything, score reel, search disc [I know, I know], bonus stepper) and safely reattach. Also a cautionary tale about fuse blocks!
Dennis Dodel is an influential bingo and flipper pinball collector that has many notable pinball credentials. He started the Pinball Trader newsletter, which became/inspired the Pingame Journal, and continues to contribute to various pinball publications. If you've ever been to ipdb.org, you've most likely seen a photo credited to Dennis.

One of my favorite bingos - Sun Valley - this 1957 beauty has great artwork, and is jam-packed with features.
Magic Squares and a single Magic Line row allow the player to move every number on the backglass.
The challenge is in getting those features lit, along with a time tree that actually allows you to reposition your numbers well, without tilting!
I love everything about Sun Valley - the knocker that goes off as you get awarded features and scores is particularly gratifying.
Mini episode! Interview with my shy younger daughter.
Gottlieb's Vari-Targets were, as per typical Gottlieb fashion, simple yet sophisticated mechanisms that allowed for a new dimension of play. Hitting the target with differing speed/accuracy provided different point values, and would send the ball flying back to your flipper.
Tonight's topic is Roto-Targets - my favorite toy from the woodrail era, that carried through the metal rail era and into some early solid states.
Ball Bowlers (contact and non), shuffle bowlers, and mannikin bowlers are all unique games. In this episode I go over some of the differences between the various types of bowlers.
