Classic Pinball Podcast discusses Centaur troubleshooting, relocation updates, and field service stories.
The Centaur's ball serve mechanism and multiball now work flawlessly after John Day's repairs
high confidence · Dr. Dave discussing ongoing Centaur repairs with John Day, stated: 'The orbs multiball works like it should 100% of the time, not 99% of the time.'
The Centaur's trunk-up failure is caused by a reset circuit voltage problem where 12V is actually reading 15V
high confidence · John Day's technical diagnosis via email: 'the reset circuit fails to hold the 6802 chip in reset during power-up...I noticed that 12 volts is actually 15 volts in this game.'
George is relocating from New Hampshire to Virginia in the Free State area (Fairfax County region)
high confidence · George's direct statement: 'We are pinball moving...to an area in Virginia called the Free State.'
George has 12 pinball machines in storage in New Hampshire that he will move to Virginia
high confidence · George: 'I've got to come back to New Hampshire to get all my pinball machines that are in a 10x10 climate-controlled storage unit.'
A customer's grandfather owned Paragon The Park arcade at Nantasket Beach, Hull, MA
high confidence · Email to Dr. Dave from customer: 'my grandfather owned the business...His grandfather owned Paragon The Park...he died in a car crash in the 1950s'
Dr. Dave received an electric shock of approximately 45 volts from a coil while working on a High Speed pinball machine
high confidence · Dr. Dave describing field service incident: 'Well, it was actually 45 volts. It was a coil voltage...It hit my head and then through my arm.'
John Jolly purchased a Firepower 2 (Williams System 7) for $300 that has a defective 40-pin MPU connector causing resistors to overheat and fall off the board
high confidence · Dr. Dave recounting email from John Jolly: 'The CPU board...got really hot when I turned it on and the brown tube things got so hot they were falling off the board...His board, this stupid 40-pin connector that connects to the MPU, to the driver board that Williams saw fit to use.'
“The orbs multiball works like it should 100% of the time, not 99% of the time. The only last one he's having trouble with is that every so often you turn the game on, and it goes dun, dun, dun, dun, like that, and then doesn't trunk up all the way.”
Dr. Dave @ ~5:00-5:45 — Status update on Centaur repair progress, showing partial success but persistent electrical gremlin
“I think the reset circuit fails to hold the 6802 chip in reset during power-up. Very confident that this can be solved by adding an MCP121-450E-T0 between the 5-volt ground and the MCU reset signal.”
John Day (quoted by Dr. Dave) @ ~6:30 — Technical diagnosis of root cause of Centaur trunk-up problem; specific component solution proposed
“I felt like, like, through my head and through my body, this electric shock. It was a coil voltage...45 volts. Still enough to get your attention. Get attention. Get me awake.”
Dr. Dave @ ~35:00 — Safety hazard incident during field service work, demonstrates real-world risks in vintage machine repair
“We are pinball moving, you'll like this, to an area in Virginia called the Free State...We're moving to what I would call horsey country.”
George @ ~10:30 — Personal life update with historical and cultural context about relocation destination
“Is this a pinball machine or a fireplace? You could if you wanted to. You could cook a sandwich on it to cook your toast.”
Dr. Dave @ ~48:30 — Humorous but serious assessment of overheating resistors on Williams System 7 CPU board, indicates potential fire hazard
“A tie beats the dealer. So you get the multiplier for that.”
Dr. Dave @ ~22:15 — Rules clarification for Blackjack EM machine, illustrates game-specific strategy differences
“I'm not giving it away because good luck finding one of any of them, never mind this one.”
Dr. Dave @ ~21:30 — Collector mindset and secondary market pricing philosophy for rare EM machines
restoration_signal: Extended diagnostic process for Centaur machine involving comparative analysis with similar machines, circuit-level voltage testing, and specialized component replacement (MCP121-450E-T0 voltage supervisor chip)
high · John Day's technical diagnosis: 'I scoped out the reset line, the 5-volt, 12-volt signals...the reset circuit fails to hold the 6802 chip in reset during power-up...I noticed that 12 volts is actually 15 volts in this game'
product_concern: FAST Pascal boards shipped with manufacturing quality control issues including backwards diodes and missing fuses
high · Dr. Dave: 'one of the diodes was backwards...during manufacture...we should have caught this in QC. I don't know why we didn't'
operational_signal: Field service technician experienced electrical shock (45V coil voltage) while working on High Speed machine due to improper grounding and missing ground prong on power plug
high · Dr. Dave: 'I felt like, like, through my head and through my body, this electric shock...It was actually 45 volts. It was a coil voltage...It hit my head and then through my arm. My arm was contacting the ground rail of the field'
product_concern: Williams System 7 (Firepower 2) experiencing critical 40-pin MPU connector failure causing continuous power draw to resistors, leading to extreme heat, component failure, and potential fire hazard
high · Dr. Dave describing John Jolly's machine: 'His board, this stupid 40-pin connector that connects to the MPU, to the driver board that Williams saw fit to use that no one else did...they lose communication...The lights instead of being pulsed every few seconds are on constantly, which makes the resistors go on there, cook, get really hot, melt the solder'

Pascal (FAST board manufacturer) experienced customer service challenges and threatened to stop responding to customers making complaints in all caps
high confidence · Dr. Dave: 'He says, in the future I will not be responding to you. If you're going to yell at me in all caps or something, don't want to work with me for little problems.'
A FAST Pascal board shipped with a backwards diode in the extra ball light circuit
high confidence · Dr. Dave recounting Pascal's email: 'one of the diodes was backwards...during manufacture...we should have caught this in QC.'
“You're 40 minutes away from me. I go, have at it. Five hours. And you've got to transport two of them. And mine works well. Right. So, you know. Have fun.”
Dr. Dave @ ~18:30 — Negotiation stance reflecting collector confidence in machine condition and unwillingness to lower price for convenience buyers
community_signal: Tension emerging between aftermarket board manufacturers and inexperienced customers who blame manufacturers for failures caused by poor wiring, alkaline battery damage, and user error
high · Dr. Dave discussing Pascal: 'He's getting a lot of guff from a couple of customers...People blow up their boards and they're blaming me...You've got to do your due diligence. Do you have any rotten wires? Do you have any alkaline damage?'
operational_signal: Professional movers lack understanding of pinball machine geometry and installation requirements, treating them like pool tables by leveling playfields, which breaks gravity-dependent gameplay mechanics
high · Dr. Dave: 'they think a pinball machine is a pool table. It's a level playing field. So they make all the things level...they take the legs that are tall and put them in the front, the legs that are short in the back...It relies upon gravity. It relies upon an incline to work. That's how the ball—the ball doesn't have a motor on it'
collector_signal: Experienced collectors hold firm on pricing for rare machines and are unwilling to negotiate significantly, prioritizing machine condition and fair value over convenience-based discounts
high · Dr. Dave on Paragon pricing: 'I said, you know, average price is $2,500. He countered at $2,000. I said, yeah, I said, maybe...I know what it's worth. If you're interested, come look at it. If you're not, don't waste my time...I'm not giving it away because good luck finding one of any of them'
personnel_signal: Dr. Dave appeared on local television program (Chronicle) in late 2019, now receiving inquiries from viewers years later due to rebroadcasts, demonstrating the lasting reach of media coverage in niche communities
high · Dr. Dave: 'That was recorded in, I think, October or November of 2019. It got released in January 2020...It's been out there for a couple of years...It's a feel-good story. It's a cool story'
operational_signal: Technicians budget extended multi-day field service for restoring multiple machines from storage, with realistic expectations about completing core work in initial visit and returning for finishing touches
high · Dr. Dave: 'So he has two games...I'll day spa them both. But it's going to probably be...I really doubt it [one day]. I'll try, but I'll hit all the high points, but I'm going to have to come back again...So he has a little more budget left in the budget for me to come back'
business_signal: Technicians purchasing FAST Pascal boards in bulk quantities (four at a time) due to high demand and component availability concerns
medium · Dr. Dave: 'I buy them four at a time. And I said, okay. So before this account came up to go out there, I made sure I got four more'
