medium confidence · Nicholas Backbone, based on schematic analysis and advice from Jeff Lawton (Mystery Pinball Theater 3000)
The 1939 Gottlieb Keen-A-Ball is a flipperless game with bingo card mechanics where players light numbers on cards A (1-7) or B (4-10) to complete bingo and win replays
high confidence · Nicholas Backbone, describing the game mechanics
Multi-Races will feature six footrail buttons controlling all features, extra balls, odds only, doubles only, feature flag, and selection change
high confidence · Nicholas Backbone, describing his ongoing homebrew project

Notable Quotes

“if I shoot the Ball up and let's say it goes through the Ball Return, I'm going to get another Ball, shoot another Ball Return. If you do that three times in a row, the selection now will lock even though I don't have any Balls in the hole.”
Len (voicemail contributor) @ early in episode — Description of Yacht Club selector lock behavior that may indicate malfunction
“I think this is extremely cool and really great... Nate has really done a tremendous amount of work to the audio to make it listenable. I'm very impressed and I can't wait to hear more.”
Nicholas Backbone @ middle section — Strong endorsement of Coast to Coast Pinball's archival project and audio restoration work
“I'd never used a router before... I only had one shot to do it and I only made one or two mistakes.”
Nicholas Backbone @ Multi-Races progress section — Reflects on the challenge and risk of routing footrail buttonholes for Multi-Races
“every bingo control has a spring, so these of course predate the bingos, but the way they work is that there is a spoon switch underneath of it”
Nicholas Backbone @ Multi-Races technical discussion — Technical insight into vintage button switch mechanisms
“I'm working on something which I think is exciting and I'm looking forward to bringing it to Straight Down the Middle: a pinball show.”
Nicholas Backbone @ closing section — Teases unannounced special project for upcoming pinball show

What's that sound? It's 4 Amusement Only, the EM and Bingo Pinball Podcast. Welcome back to 4 Amusement Only, this is Nick Baldridge. First up, I got a voicemail on the bingo's line from Len, friend and contributor to Bingo Row in York every year. Hello Nick, hey I have a yacht club here. Here's my question, the ball return, if I If I shoot the Ball up and let's say it goes through the Ball Return, I'm going to get another Ball, shoot another Ball Return. If you do that three times in a row, the selection now will lock even though I don't have any Balls in the hole. Now I play the Gay Time, it's exactly the opposite. I can shoot as many Balls in the Ball Return until up to I shoot the fourth Ball and then I'm locked in. So I guess the question is, is the Yacht Club working right? It may seem like a simple problem. Looking at the schematic, there's not much to really go off of, so I think the Yacht Club's provides elevation for the true carting operation, the συ 81 verde л downwards or a trenädушеч pytanie selection ability an So I would suggest checking trough number four carefully. The only other things that are in the circuit of note are the timer itself and that stepping and a normally closed switch on the selector lock relay itself, which is opening appropriately or the coil would fry. So on bingo trough switches, there is a metal spacer, which can sometimes be wedged outside of the switch, I'm not a fan of pinball, especially if a particularly hard ball strike hits it or if someone's been messing with the trough in order to clean the switches or repair something and inadvertently doesn't. I'm certainly guilty of that. So I'd suggest concentrating my efforts there, as that makes the most sense. Thanks for my change of heart goes to Jeff Lawton, the man who wrote the bingo book. I contacted him because the trough switch is drawn and the schematic is being normally closed and for whatever reason that caused me to just close my eyes and look past it But he set me straight So thanks to Jeff and thanks Len for the interesting question Next up have you heard Coast to Coast Pinball's newest offering? He is taking the tapes that Roger Sharp recorded for his book Pinball that was written in the nineteen seventies. These are interviews with electromechanical luminaries and he is releasing them in podcast form. I think this is extremely cool and really great. The first episode focuses on Harry Williams and unfortunately they're in a crowded cafeteria but Nate has really done a tremendous amount of work to the audio to make it listenable. I'm very impressed and I can't wait to hear more. Do yourself a favor if you enjoy electromechanical games and seek out that podcast. It's Coast2Coast Pinball. That's the feed that it features under. Next, more work continues on multi-races. I did some woodwork this past weekend and routed out the buttonholes that are necessary for the footrail controls that I'm going to be adding to multi-races. There are going to be a total of six buttons In that foot rail area, one to play all features, one for extra balls, one for odds only, one for doubles only, one to light the feature flag, and then one to change your selection.

The buttons I found on Turf King at least have no springs, which I was a bit surprised to learn. Every bingo control has a spring, so these of course predate the bingos, but the way they work is that there is a spoon switch underneath of it, and that spoon has a blade stiffener behind it, sugg St Massens, Steertun, The last two I'm going to have to substitute bingo buttons and a big thank you to Jim Holder, bingo collector in Pennsylvania who's also a big part of bingo row every year. He has provided me with some old lock bars for bingos, magic screens that have very worn left and right buttons and I'll be able to repurpose those for now until I can find originals to slot in place. So preparations for York are in full swing and I should have more to announce on that front soon. I'm working on something which I think is pretty exciting and I'm looking forward to bringing it to the show. I also working on a super secret special project which I may or may not have finished in time for York but I should have it finished in time for next year So today featured game is Gottlieb 1939 Kina Ball This is a very interesting game I just saw it come up and it has a very bingoesque back glass There are two different bingo cards and the numbers 1 through 7 are posted on the first card marked A and the numbers 4 through 10 are marked on card B The launch of each ball, the ball can go one of a few different ways. There are two sets of lanes at the top, two on the left and two on the right, which allow you to choose either A or B, the card A or B. It will also light up the A or B on the back glass. This is important later on. And then the series of bumpers that progresses from there is set up in a fairly difficult or confusing pattern. But in the center of the game, There are three different bumpers and one ball return hole. I assume it's a ball return hole. It might be blocked underneath but it is not labeled like a gobble hole. At any rate, each of these things will award you one skill point. The neat thing about the skill points is that they're a carryover feature. and from the factory once every 30 skill points you win a replay. So even if you're a terrible player like myself, eventually they'll throw you a bone. But the main goal is to light up one entire bingo card and then make sure that you have the appropriate letter lit as well, A or B. I think this game looks like a ton of fun. It's a flipperless game with a fairly unique concept between the bingo cards and the skill points which accrue otherwise. So this is one that is now on my list and I'll be looking for a nice one here one of these days. At any rate, thank you very much for listening. My name again is Nick Baldridge.
