# Episode 79 - Lighted Scoring **Source:** For Amusement Only EM and Bingo Pinball Podcast **Type:** podcast_episode **Published:** 2015-05-29 **Duration:** 4m 17s **Beat:** Pinball **URL:** https://foramusementonly.libsyn.com/episode-79-lighted-scoring --- ## Analysis Nick Baldrige discusses the history of lighted scoring systems used in early EM pinball machines from the 1930s-1950s, before the adoption of score reels. These systems used backlit scoring on the back glass controlled by steppers, with scores integrated into the artwork itself. The episode explains the mechanics of how steppers advanced scoring displays and introduces upcoming episodes on score reels and mechanical reset systems. ### Key Claims - [HIGH] Pinball games in the 1930s, 40s, and early 50s used backlit scoring on the back glass rather than score reels — _Nick Baldrige, host of For Amusement Only EM Pinball Podcast, opening segment_ - [HIGH] Lighted scoring systems used steppers to control which numbers lit up on the back glass, with one stepper per scoring category (hundreds, thousands, hundreds of thousands, replays, millions) — _Nick Baldrige explaining the mechanics of lighted scoring systems_ - [HIGH] When a stepper reached 900, the next step would trigger the next higher stepper (e.g., from hundreds to thousands) via a carryover switch — _Nick Baldrige describing stepper mechanics and carryover functionality_ - [HIGH] Scores in lighted scoring games like Humpty Dumpty and Jack and Jill were integrated into the back glass artwork itself with rudimentary animation — _Nick Baldrige citing specific game examples with lighted scoring integration_ - [MEDIUM] Reset relays were an invention from the 1940s used to automatically reset scoring steppers to zero position after a game ended — _Nick Baldrige noting he has never seen a 1930s machine using a reset relay, implying 1940s origin_ - [HIGH] Machines from the 1930s used mechanical reset systems rather than electrical reset relays — _Nick Baldrige contrasting 1930s mechanical resets with later electrical reset relay systems_ ### Notable Quotes > "In the 1930s, 40s, and the early 50s, games were not yet using the iconic score reels that one usually associates with EM pinball machines.

It's For Amusement Only, the EM and Bingo Pinball Podcast. Welcome back to For Amusement Only. This is Nick Baldrige. In the 1930s, 40s, and the early 50s, games were not yet using the iconic score reels that one usually associates with EM pinball machines. Instead, they used backlit scoring on the back glass. The way that this worked was pretty much universal. It only varied in the number of steppers which controlled it. So even though you don have a stepper for each digit of the score you do have a stepper to indicate hundreds or thousands or hundreds of thousands and a stepper for number of replays or if set in novelty mode number of millions or whatever other indication there might be that you have achieved a special. The slided scoring is controlled purely by the stepper, so a different set of numbers will light up based on which position the stepper is in. As the stepper reaches its peak, its apex, once it gets to 900, the next step will trigger the thousandth step. This works in almost precisely the same way that score reels work, which I'll be getting to very shortly in a series on score reels. but there a carryover switch which is hit and it will tell the machine that once it reached this position it needs to step the other stepper As the steppers are actuated and the score starts climbing the lights on the back glass will change. And the scores are typically integrated for the lower scores in the back glass artwork itself. So, as in machines like Humpty Dumpty or Jack and Jill or any of the fairy tale series from Gottlieb, there's back glass animation. well, most of the lighted scoring games used a very rudimentary back glass animation to display the score until you reached a certain threshold, say 100,000 points and at that point it would light up the appropriate spot on the back glass and that would remain lit when the game is reset the steppers release and go back to the zero position In some instances they will continue to step until they reach the zero position On these machines that's governed by a reset relay, an invention which came about in the 1940s, at least as far as I know I've never seen a machine from the 1930s that used a reset relay in order to reset the scoring to default. Machines from the 30s were reset mechanically, and I'll get into those in a later episode as well. But one thing that these machines all have in common is the lighted scoring, which lit up the back glass. Well, thanks again for joining me. My name again is Nick Baldrige.
