“when they brought Funhouse in... Rudy just was so infuriating laughing at you. I dumped so many quarters in”
Chad Dubovsky @ early in interview — Illustrates his formative experience with pinball and emotional connection to arcade games
“by trade I'm a mechanical engineer and the mechanical side of pinball just, it's really enjoyable to me. I'd like to see why things break, see if I can fix them in a better manner”
Chad Dubovsky @ mid-interview — Explains his motivation for collecting and restoring EM machines from an engineering perspective
“I miss those auctions because they were fun just as you started to get into it... you see all the same people and everybody kind of knows what you're looking for... everybody kind of works together for the most part”
Chad Dubovsky @ mid-interview — Reflects nostalgia for auction culture and community collaboration in the early 2000s EM scene
“the back glass was so peeling, you know, a sneeze would have made it completely clear glass... we ended up picking this game up for like 25 bucks”
Chad Dubovsky @ mid-interview — Describes the condition and bargain acquisition of his Beach Club bingo machine
“They did it all with relays, steppers, and massive discs. It's crazy.”
Nick Baldrige @ discussing Magic Screens — Expresses amazement at the complexity of mechanical bingo machine design
“I really enjoyed it. I went up and down the row and played a whole bunch. I don't think I played all of them because I kept going back to that Nightclub.”

community_signal: Chad reflects on the decline of arcade auctions as a major source for EM machines in the early 2000s, noting that Super Auctions are now rare. This indicates a market shift away from auction-based acquisition toward other channels.
high · Chad states 'I really miss those auctions because they were fun' and notes that Super Auctions are 'still out there and they're still running auctions but they're very few and far between'
restoration_signal: Chad and Nick discuss difficulty sourcing specific EM parts, particularly uncommon items like magic screen mechanisms and complete game heads (e.g., Hi-Fi heads).
high · Chad: 'parts are kind of hard to come by if they're not standard coils' and discussion of Hi-Fi head availability lasting years without success
community_signal: The York Show featured a dedicated bingo machine row organized by Nick Baldrige, generating interest from collectors like Chad. Plans exist to expand this in future years.
high · Chad states: 'I really enjoyed it. I went up and down the row and played a whole bunch' and discussion of plans to bring bingo machines next year in smaller numbers
design_philosophy: Chad approaches EM machines from a mechanical engineering perspective, valuing the design logic and repair/restoration aspects as much as gameplay. This reflects a specialized collector mindset.
high · Chad: 'by trade I'm a mechanical engineer and the mechanical side of pinball just, it's really enjoyable to me... see if I can fix them in a better manner'
restoration_signal: Chad is documenting and preserving rare sound mechanisms from early gun games, planning to contribute audio files to community archives for preservation.

high confidence · Chad Dubovsky, describing the Flying Carpet acquisition and current restoration work
high · Chad discussing Flying Carpet: 'I'm going to contact the gentleman who does that and see if he has access to that... so we can make it... just upload the file for him so he can preserve that'
gameplay_signal: Chad shows strong interest in bingo games with multiplier scoring features (double/triple/quadruple), particularly Magic Squares variants like Nightclub and Sun Valley.
high · Chad repeatedly expresses interest in Magic Squares specifically because of multiplier mechanics: 'I like the aspect of the squares because when you rotate, you can actually go from lining up horizontal to lining up perpendicular'
venue_signal: The York Show and Allentown Show are active annual events where EM collectors acquire machines, share knowledge, and form community connections.
high · Chad acquired Flying Carpet at 'the past Allentown show' and met Nick at York Show; discussion of plans for future bingo displays at York Show
market_signal: Regional variation in game availability is significant; Chad notes he's 'on the edge of six card territory' in Pennsylvania with 'a pretty good selection' compared to harder-to-find games like Magic Squares.
high · Nick tells Chad: 'You're right on the edge of six card territory, but there should be a pretty good selection around you'
restoration_signal: The Ginsburg batch acquisition yielded approximately 10 bingo machines, with roughly 80% successfully restored to working condition despite significant deterioration.
high · Chad: 'got probably 80% of them working. I think there was a variety that the cabinet was just in shambles. We couldn't get that one back to to playing'
collector_signal: Chad collects across multiple EM categories beyond pinball: gambling machines (Joker Ball), gun games (Flying Carpet), puck bowlers, and other mechanical amusement devices.
high · Chad: 'I kind of just anything I see that is different... I always like to have something that may interest just about anybody'
