Stern Electronics' origins: Chicago Coin bankruptcy, board copying, and early solid-state games.
Chicago Coin was founded in 1933 by Sam H. Gensberg as a division of Chicago Dynamic Industries, operating a trade-in business model for coin-op conversion kits.
high confidence · David Dennis directly states this as documented history in the episode
Stern Electronics acquired Chicago Coin Machine Mfg. Co. manufacturing assets at bankruptcy sale in December 1976 after Chicago Coin defaulted on a loan, specifically to avoid assuming Chicago Coin Machine Mfg. Co. debt from Magnavox patent litigation.
high confidence · David Dennis explains the bankruptcy asset sale mechanics; Gary Stern's legal background enabled this strategy
Stern reverse-engineered Bally's solid-state circuit board design by acquiring Universal Research Laboratories (URL) and copying the board architecture, resulting in boards identical to Bally's that used the same CPU, solenoid driver, lamp driver, transformer, and rectifier components.
high confidence · David Dennis provides detailed technical breakdown; notes that reproduction boards like Alltech work on both Bally and Stern machines of the era
Bally sued Stern over the copied board design, and Stern was required to pay Bally a royalty for each solid-state system sold, though specific royalty details were not found in research.
medium confidence · David Dennis states this occurred but could not find detailed terms; describes Bally's strategy to control industry standards
Sam Stern purchased 49% of Williams Electronics from Harry Williams by walking into his office with a business proposal; Williams later flew his personal airplane around Chicago to consider the offer before agreeing.
medium confidence · David Dennis recounts the 'famous airplane story' but doesn't provide a primary source; framed as anecdotal industry lore
Jerry Koci, head engineer of Chicago Coin, worked in the pinball industry from 1936-1977, designed over 30 games, and repositioned Chicago Coin into wartime manufacturing of sub-assemblies, with NASA contracting Chicago Coin for manufacturing in 1950.
high confidence · David Dennis cites Pinball Compendium book as source; systematically documents Cokie's career and contributions
“I felt we could make a business, meaning pinball, but we couldn't do commodity pinball. One that looked like it was the same as everybody else. So we created wide bodies and these various other innovations which allowed us to price them anywhere we wanted.”
Nolan Bushnell (Atari) @ Early in episode — Explains Atari's business strategy in pinball; cited by Dennis Creasel from Pinball News article explaining widebody choice
“I've bought some pinball companies, but I've never bought a pinball machine, and that's a true answer.”
Gary Stern @ Mid-episode discussion of Stern family — Reveals Gary Stern's purely business-focused relationship to the industry, contrasting with typical collector mentality
“Whatever's on the line.”
Gary Stern @ During Gary Stern profile — Illustrates Stern's pragmatic, operator-focused mindset—his favorite game is whatever generates revenue
“A bash toy and two ramps, really though. What else do you need? That's what John Borg says.”
David Dennis @ Opening segment — Humorous reference to John Borg's design philosophy; establishes tone for discussing early Stern designs
“He would much prefer doing that as opposed to actually running the ins and outs of a company. Those are two totally different skill sets.”
Ron Hallett @ Discussion of Harry Williams vs. Sam Stern roles — Articulates the division between innovators (Williams) and business operators (Stern) in early pinball
“Bally, when they came up with their solid state system, they tried to trademark it, not just their system, but any solid state. So if you made an electronic pinball game, you had to use their system.”
David Dennis @ Solid-state technology section — Documents Bally's aggressive IP strategy to monopolize solid-state pinball industry standards
“You can use it on any Bally or Stern of the era. Well, what are the odds of that? What are the odds that Bally sued them?”
David Dennis — Rhetorically highlights the near-identical board architecture; foreshadows legal consequence

Gary Stern has never purchased a pinball machine for personal use, only pinball companies, and when asked about his favorite game stated 'Whatever's on the line,' though Jeff Patterson of This Week in Pinball obtained a quote where Gary mentioned enjoying Flight 2000 and Steve Kirk games like Meteor.
high confidence · Direct quote from Gary Stern cited from This Week in Pinball article; David Dennis verifies this unusual detail
Stern's first releases were electromechanical holdovers from Chicago Coin (Stampede, Rawhide) designed by legacy Chicago Coin engineers, followed by their first solid-state game Pinball in 1978, with 594 EM units and 1,650 solid-state units produced.
high confidence · David Dennis provides production numbers and designer credits; games are documented in Pinball Compendium
“He was probably like, ah, I've kind of had it.”
Ron Hallett @ Discussion of Jerry Cokie's career end — Speculates on aging engineer's retirement during industry upheaval in mid-1970s
personnel_signal: Jerry Cokie, longtime Chicago Coin head engineer (1936-1977), designed 30+ pinball games but receives minimal recognition in industry history; represented transition from wartime manufacturing to pinball design
high · David Dennis dedicates segment to Cokie's career, sourcing from Pinball Compendium; notes his work from Bermuda (1947) to Stampede (1977); cites NASA manufacturing contracts in 1950
industry_signal: Chicago Coin unable to compete with Gottlieb and Bally in 1970s; chose non-flipper game focus and video games rather than direct competition; patent litigation with Magnavox on video knockoffs precipitated financial crisis
high · David Dennis documents Chicago Coin's pivot away from flippers to gun games, shuffle alleys, and video games; notes 1974 Magnavox lawsuit along with multiple companies; financial trouble led to bankruptcy
historical_signal: Sam Stern's acquisition of 49% Williams Electronics from Harry Williams; anecdotal account of Stern proposing deal, Williams flying personal plane to consider, then agreeing; represents early post-war pinball consolidation
medium · David Dennis recounts 'famous airplane story' as industry lore; not primary sourced but presented as known anecdote; documents Sam Stern's role in building foundation for post-war pinball
design_philosophy: Division of labor in early pinball: Harry Williams as innovator/engineer (score reels, multiplayer, tilt bob mechanisms) preferred design to business management; Sam Stern as operator/businessman handled company operations
high · Ron Hallett articulates distinction; David Dennis documents Williams' transition to semi-retirement in 1960s to focus on personal tinkering projects; Sam Stern documented as business-focused executive
