Detailed restoration and gameplay analysis of 1979 Bally's Harlem Globetrotters.
Harlem Globetrotters was released in September 1979 with 14,550 units produced
high confidence · George stated this as factual industry data during the episode introduction
The game was designed by Greg Mayak (not 'Kemic' as George initially thought)
high confidence · George corrected pronunciation after consulting with J.R. from Maine; verified against IPDB
Margaret Hudson served as the screen/playfield artist for Harlem Globetrotters and other Bally titles
high confidence · George referenced IPDB verification of artist credits; Hudson also worked on 8-Ball Deluxe and Frontier
Greg Mayak's signature design element is an opaque red post strategically placed on the playfield
high confidence · Dave confirmed this as a recognizable design signature across Mayak's X-series games
New linear 5-volt regulators (PU5-style) used in WPC ramp games do not work reliably in older Bally/Stern applications due to excessive current draw
high confidence · Dave described technical troubleshooting experience; confirmed by John Day during restoration
George owns an original day-one mylar on his Harlem Globetrotters that he has not removed
high confidence · George stated personal ownership details about his machine from John Toast collector in New Jersey
The Harlem Globetrotters playfield features inline drop targets with a post/rubber that can cause unpredictable ball feeds
medium confidence · Dave and George debated the feed consistency from inline drop targets based on impact angle; George's does not exhibit the issue, Dave's does
Dave charges $100 for Andrew Weebly's custom soundboard with adjustable pitch, sustain, and volume controls
high confidence · Dave stated pricing during discussion of soundboard customization features
“The K is silent. Like Knife.”
George @ ~6:00 — Humorous correction of designer Greg Mayak's pronunciation, establishing the designer's correct name for industry documentation
“This thing has to go back here where Greg put it. You know, I'm not going to put it somewhere else. I'd like to hide it where he hid it so it stays original that way.”
Dave @ ~9:30 — Demonstrates Dave's restoration philosophy of preserving designer intent and original playfield layout
“It puts out 2 volts, and wah, wah, you don't get the game to boot... The game just sits there, and the MPU says, I need 5 volts. Dude, I'm not going to boot up until I get to 5 volts.”
Dave @ ~45:00 — Technical explanation of voltage regulator incompatibility issue relevant to board rebuilding community
“Wow, these spinners, you've done it again, these spinners spin better than new.”
Dave (quoting PJ's comment) @ ~40:00 — Validates Dave's spinner restoration technique and playfield protector installation quality
“It's almost done at that point. I had Maureen come down and look and she goes, wow, this thing is gorgeous. It looks like a clear-coated new old stock playfin.”
Dave @ ~35:00 — Professional third-party validation of Dave's playfield restoration quality standard
“I just tweak the pitch a little bit, and boom, it's like, ah, that's Harlem right there. That's what you sound like. It's perfect.”
Dave @ ~56:00 — Demonstrates how customizable soundboards enable restoration to match player memory of authentic game audio
“The one thing that I wanted to point out was the Harlem bumper caps. I have a set of three that are the reverse of what comes with the game.”
George @ ~63:00 — Documents potential manufacturing variance or error in reproduction bumper cap colors
“You just have to line it up so that it's not buzzing on you and make sure that it's – it's two stop points are stopping where it should.”
restoration_signal: Dave documents generational differences in playfield protector design: older versions (used on Kingpin, Pinball Pool, Harlem) featured small holes for in-lane metal guides requiring careful installation; newer versions cut out full lines for guides to simplify installation but create larger gaps that may collect dirt
high · Dave contrasts the two protector generations: 'They made small holes for you to put the metal guides back in... the new ones they're doing... they cut out the whole line for those in-lane guides so you don't have to pull them up anymore. But now you have these big lines of no plastic there.'
product_concern: Linear 5-volt regulators designed for WPC ramp games (PU5-style SB model) are incompatible with older Bally/Stern applications; regulators shut down under excessive current draw, outputting 2V instead of 5V, preventing MPU boot
high · Dave's troubleshooting discovery and confirmation by John Day: 'The 5-volt regulator... works really well in that application... does not work so well in the old-school Bally and Stern application because it draws too much amperage... it puts out 2 volts, and... you don't get the game to boot.'
restoration_signal: Dave's spinner restoration process includes: removing artwork with mild abrasion, grinding smooth, applying appliance white epoxy paint, applying basketball-themed stickers, buffing to appearance of new old stock, and mechanical tweaking for optimal spin performance
high · Dave describes full spinner process: 'I basically kind of wiped off most of that artwork... grinded it down... took some appliance white epoxy paint... let that dry... took some stickers I got from Marco of Harlem Globetrotter basketball stickers and threw those on there... did my usual tweaking the spinners for maximum spins.'
product_concern: Inconsistent ball feed from inline drop targets on some Harlem Globetrotters; rubberized post positioned at ball return area bounces balls unpredictably depending on drop target impact angle

Dave @ ~68:00 — Practical troubleshooting advice for ball gate alignment issues common in Harlem machines
medium · Dave and George discuss: 'the feed from the drop seems to be... if you hit the target more left it will come out smooth... if you're more center or to the right it... hits that that rubber and then you know it can go pretty much anywhere it wants to.'
product_concern: Right-hand side ball gate mechanism on Harlem Globetrotters can stick or bind; issue is typically mechanical alignment and cleanliness rather than fundamental design flaw
medium · George references Pinside discussion: 'somebody was having issues with the ball gate on the right-hand side... you have to take it all apart and just clean it real good and maybe put a little bit of lubrication in there.' Dave confirms: 'Just takes – you just have to get it lined up the right way.'
manufacturing_signal: George possesses a set of three Harlem Globetrotters reproduction bumper caps with reversed color scheme (red and blue inverted from production standard); unclear if intentional variant or manufacturing error
low · George states: 'I have a set of three that are the reverse of what comes with the game. So all the colors, the red and the blue are reverse. And I don't know if that was done on purpose or not.'
licensing_signal: Approximately 10+ years ago, Bally licensing rights for reproduction parts (bumper caps, targets) were terminated, creating run on reproduction stock; George and Dave both made significant purchases during this window
medium · George recalls: 'when the license was yanked for Bali bumper caps and targets and there was a run on that stuff... I was one of the people that bought, I don't know, hundreds and hundreds of dollars of stuff from Steve.'
design_innovation: Andrew Weebly's aftermarket soundboard for Harlem Globetrotters adds pitch control adjustment in addition to original volume and sustain controls, enabling precise audio tuning to match authentic game sound characteristics
high · Dave demonstrates: 'He added a pitch control... I adjusted the sustain notes to be a little longer... then let me try the pitch. I just tweak the pitch a little bit, and boom, it's like, ah, that's Harlem right there.'
restoration_signal: Dave collaborates with professional playfield artist Maureen for touchup work on restorations; third-party validation of restoration quality provides market confidence
high · Dave describes: 'I had Maureen come down and look and she goes, wow, this thing is gorgeous. It looks like a clear-coated new old stock playfin.'
content_signal: Growing trend of pinball restorers streaming restoration work on Twitch; Chuck Webster and Ryan (Franklin, NH) are active streamers; technical and presentation challenges noted (audio levels, live risk management, editing limitations)
medium · George watched Chuck Webster stream: 'all I hear is the Rolling Stones... you should be able to hear what you're doing. He's doing a restoration. I couldn't hear what he was doing.' Ryan's stream featured technical mishap: 'the thing fell out of the cabinet and you should have seen him he turned bright white.'
gameplay_signal: Dave configured Harlem Globetrotters with non-standard rule set: spinners activated independently rather than simultaneously; only one spinner scores at a time, activated by pop bumpers/kickers/center hole, increasing difficulty and accuracy requirement
high · Dave explains configuration: 'I set it up, only one side is lit at a time... Something changes it so it goes to the other spinner. So it makes it more you have to be accurate, well, to which spinner you're going to shoot for.'
gameplay_signal: Dave configured saucer targets to reset randomly rather than requiring spell-out sequence, simplifying scoring path and reducing play complexity
high · Dave states: 'I adjusted that so that the targets go back up once you go in... Random. That's random top.'
