Max’s Garage
Добавлен 14 янв 2013
My name is Max and I am a college student majoring in computer science who has an appreciation of both old and modern technology and engineering.
Over the years I have gained a lot of experience either by figuring things out myself or watching fellow RUclipsrs such as Adrian’s Digital Basement, LGR, Mr Carlson’s Lab, The 8-Bit Guy, and many others.
I have the most experience with computer hardware and software related repairs but anything electronic that interests me I will probably make a video about as I want to continue branching out and learning new things.
I have no regular release schedule as I do this for fun only. I hope you enjoy the content I create.

New Pinball Restorations for 2025!
At this rate the pinball restoration addiction is in full swing. After having restored four pinball machines so far, I now have three new project machines needing work - which means multiple new restoration series are coming soon. In this video we take a look at what I received, do some initial inspection and get a general idea of what needs to be done with each machine.

Pinball Circuit Modification: Installing a power switch in a machine that doesn’t have one
Просмотров 12914 дней назад
In this video we revisit the 1948 Chicago Coin Catalina because I want to install a power switch so that the machine can be turned fully off without unplugging it from the wall. The way this machine was designed from the factory doesn’t allow for that, so watch as I modify the circuit in order to install a “true” power switch.

NES Distorted Video Signal - a simple fix?
Coils don’t really “go bad”, barring mechanical damage. It’s typically gummed up mechs or switches like you concluded. Coils are just a length of wire. Just ohm out the coils and see if one is off of the others that are the same ones to see if one got melted or something. The LEDs make it pop. Very nice.
The decrement button on the bottom is for “gambling”. The operator could cash someone out if they won a bunch of free games. Might consider cleaning all the gummed up old grease off before adding more. Would stay functional longer. But that’s a beautiful machine. Never heard of it before.
I got one whats the worth of it ?
You need a mic. Badly
Probably will get one soon. I’ll see what I can find
Great video and collection. Might want a BT mic for future videos.
Do you have any interest in arcade machines aswell? I collect both pinballs and arcades and would love to see you also restore arcades!
@@AnthonyPresley-l8f That would be fun! Haven’t found any locally for a good price but I’m sure I’ll do an arcade game one of these days.
@ glad you have interest in arcades aswell, recently picked up a spy hunter cockpit arcade that I’ll be restoring. Definitely a grail for me. If I were you I’d look for an arcade that has a lot of parts available like a Ms Pac-Man, galaga, etc. would be better to start with an easier to work on game I would think.
Nice pickups. I'm sure they'll ALL be fine. Just plug them in and fire them up! 😜 Looking forward to watching you work on them.
Hi Max, what is your engineering background or are you just a keen enthusiast
Mostly an enthusiast since I’ve learned most of this myself but I do have some IT experience and am currently studying computer science and engineering.
@ very impressed Max keep up the good work
I'll give you credit buddy. I don't even bother with the EM machines. Box full of relays isn't fun for me, and I'm way older than you.
This machine has been restored! Visit the link in the description to watch my restoration series on this Phoenix.
Great video. I have been working on several pinball machines from the 70’s. I am inspired to work on some wood rail pinball machines someday soon. I really like the way the legs and trim looks after you sanded and clear coated. I am so impressed with your efforts.
Can I mail you my 1986 nes to see if you can get it to work?
Awesome job Max! I really enjoyed part 1 and 2. Your perseverance with Catalina paid off. I have worked on Gottlieb, Williams and Bally electromechanical pinball machines but not a Chicago Coin yet. It is obvious that you have learned a lot along the way from the experience. I look forward watching more of your videos and hope that you make more pinball videos.
@@davidmorgan4122 Thanks! I’ve since uploaded part 3 as well as restorations on 3 other machines after I finished Catalina so feel free to check those out. More pinball videos are in the works!
Hi Max great videos. Watching from Great Britain. Always wanted a Bingo but they are few available in the Uk. I’ll keep looking and maybe one day will acquire one
Don't waste your time testing those caps. They are over 40 years old, just replace them. Use at least a 6800 for the 5V line. You'll notice the one big cap on your sound card is actually leaking.
hey i loved your vid and i gotta ask i have a 512k with a plus anaglouge board since mine had no traces left and was burned up and i have a vertical collapse what would you recomend
Cool!
Great video!! Thanks a lot!!!! 🙂
Great video Max! I'm restoring a sister Chicago Coin pinball "Baseball" 1948. This video saved me a lot of time trouble shooting. Also, your production values on your video get an A+ Thanks for doing this!
What does the attract mode sequence doing or testing?
On pinball machines starting in the late 70s, when the machine is in game over mode it would flash the lights on the playfield and sometimes make sounds, which would attract people to the machine hence the name “attract mode”. This machine never had that from the factory, but with the new CPU board I installed it adds a flashing light sequence when it’s in game over, so it now has an attract mode.
@@MaxsGarage I thought all 70's pinball games had an attract mode flashing light sequence during the game over but I didn't know that the Gottlieb System#1 games didn't have an attract mode.
@@waynegram8907It’s only the very early solid state games that don’t have it. For example my 1978 Williams Phoenix doesn’t have it either. It wasn’t until 1979-1980 where games started including that.
@@MaxsGarage Ok thanks, I guess it became a standardization by 1980 for Solid State games. I guessing those Gottlieb Spider Chips for the System 1 were made by Rockwell part number 11660EF which are Both ROM & RAM chips in one chip package which I'm guessing outputs various strobe output signals for the Lamp Lights. It seems that Rockwell made custom Spider Chips for Gottlieb for the System 1 pinball games.
@@MaxsGarage I thought you were using the Attract Mode as a way of testing the playfield light lamps to see which lamps weren't working correctly.
Great job! Ball moves around on that playfield like glass. Cant get much better than that. Thanks for going ahead and documenting this process. 👍🏻👍🏻👍🏻
Glad you enjoyed! It’s amazing what a simple clean up and wax job can do!
Great work, Max. I figured, based on the other videos that you'd get this one looking good and playing. I say we live in tgis weird golden age of pinball and arcade repair because of all the videos that are out there. Thanks for making the videos and adding to it.
Glad you enjoyed!
The Famicom have jailbars (vertical lines) And all non RGB 8 bit Nintendos jabe bery baddly dot crowing on all vertical color obcects wnen scrolling horizontally.
Looks like the end of the video’s got some audio issues. Tried to fix it but can’t get the audio for that specific part to sync. Hopefully it’s understandable enough, I mention that the U5 spider chip contains the CPU board ROM code so with that chip being bad it could never have started, and that in part 4 I’ll be installing the new CPU board and replacing the shorted driver board transistor.
What does the Strobe signal do? the Spider chips have multiple strobe signal inputs which I think are at different strobe frequencies. If you take your oscilloscope and measure the strobe input signals they should be at different frequencies and duty cycles? I'm not sure why they are strobing or using strobe signals for the switches but the CPU must be scanning the switches so how.
I’m not an electrical engineer so I have no idea. All I know is that there wasn’t any pulsing on the strobe signals which meant the custom spider chip creating those signals was bad, so a new CPU board was my only option unless I risked buying another potentially broken original CPU board.
Ah bummer that the spider chip is a goner. But good troubleshooting getting to that point and all the other stuff you did like the ground mods. I know you'll get it going. Thanks for the video showing the process.
Thankfully we have resources to replace these cpu boards. Back in the day when this would happen they would part out hundreds of these games due to bad spider chips and no alternative.
I’m one of those who would prefer to fix original boards so they can still be used, but in this case where a spider chip went bad, new boards are a godsend!
Any reasons why they used a separate ground reference only for the 42vdc and 60vdc? its isolated from the other grounds for some reason, its ground is NOT tied connected to the pinball games backbox ground?
@@waynegram8907 I’m not entirely sure but there is a separate transformer that runs the higher voltages so the HV ground might be tied to that transformer, which would explain the separate grounds.
Idk about the iPod but now I want a Volvo truck
Great series looking forward to watching pt3 as I go through one I just got ahold of
Great job! Increase the pitch of the game and add some 321 oil to the spinner axel, and thats gonna be an awesome time!
Could you upload those videos to Archive?
Great job! Machine looks awesome it almost looks like new.
Great restoration. I am a 62 yo man who played these machines as a kid. My friends mom owned a beer joint and we were allowed in during the day. Great fun and they were for amusement only. 😉😉
Very cool! Glad you enjoyed the restoration.
I'm having problems with this iPod, I use Cf adapter with micro SD, but I need to format it with Windows. Have you had any idea how to do it?? I'm already getting desperate
Use to play these in Australia☺
Русские быстрее тебя работают.(болтаеш много)....
This was my first pinball. Pretty fun game
I’ll be super impressed if you could get this entirely working. Vintage bingo machine in my opinion aren’t worth touching since they don’t have much value and their complexity is insane
Parts 2 and 3 for this machine are already uploaded and are in a playlist on my channel. It took a while but I was eventually able to get all its issues sorted! The detailed documentation really helps to understand the complexity of these machines.
Awesome video series on this Night Club! I'm fixing up my Bally Show Time right now and have it working great mechanically but doing some cosmetic fixes. Can you detail which LED bulbs you used specifically in the backglass? When you pulled them out of the box, they looked like Comet Pinball LEDs which is where I get all mine for my other pinball games. I like the look of the ones you got so would like to experiment with those. Maybe you could add links to the description? Thanks for an awesome in-depth series!
@@BrentKelley Yep I used Comet Pinball LEDs specifically the frosted warm white “1SMD non-ghosting bulbs” on their website. Night Club uses 20V bulbs in the bingo card and I imagine Show Time is the same so I’m not sure if those can be upgraded. The rest run off 6V. Glad you enjoyed the series!
Max, you do a very good job of detailed explanations of problems, how you fix the problems, and how you test for bad parts. This is very helpful to us at home trying to repair our pinball machines. Thanks
Glad I can be of help!
The Williams logo? That is an upside down Motorola logo - they are very similar.
You have to replace all the electrolytic in the power supply including the very big one.
In part 2 I checked all of the power supply caps for proper capacitance and leakage and they were all good including the big lamp cap. From a preventative maintenance standpoint it certainly wouldn’t hurt but if they are still working properly there isn’t an immediate need to replace them.
You have to look at the Powers’s-ply
I did that in part 2 before I turned the game on
I loved that computer growing up. If memory serves, the joystick is connected to the 9-pin connector on the left. I believe the 9-pin on the back is for the cassette deck to load/save programs.
3d print posts..
I looked online but couldn't find a STL for that specific post.
I love seeing into them so much. They are beautiful
Looks great, Max. It's always amazing how much a simple cleaning can go a long way to make the game look better. I have to second the "No Grease" usage on the coil mechs. Take those sling shots and flipper assemblies apart and clean. No Grease on metal to nylon. Only metal on metal needs any greasing. Go to the Williams Phoenix game and rebuild those flippers for practice. Gottlieb Flippers are more complicated. Clean, not grease. Also the bullet style bulbs are a nice touch, although not necessary. Lastly, the coil sleeve for the knocker is incorrect style. The longer sleeve is usually necessary so the plunger doesn't wiggle free. But terrific job so far. Looking forward to the rest of this and the Phoenix videos.
Thanks for the tips. I’ve had to disassemble coils on the Phoenix when fixing its drop targets so cleaning the plunger and inner part of the sleeve on the flipper coil should be no problem. I saw that the coil sleeve on the new knocker coil was shorter but I manually moved the knocker and it seemed secure. I’ll replace it if it becomes a problem.
@@MaxsGarage it looks great so far
Please do not grease the flipper plungers! Over time it will gum back up with the coil dust and other debris from the flipper mechanism. Installing a new coil sleeve should go a long way. No lubricant needed as the coil sleeve is nylon and is self lubricating
Got it. Cleaned up the plunger/sleeve and it operates smoothly.
@@MaxsGarageexcellent work! You are doing a great job
Yes. CT is center tap. Transformer definition. You are counting pins on the processor wrong on the second side. They count in a circle.
@@geeteoh1 I ended up realizing that after editing. I'm surprised I didn't catch that.
@@MaxsGarage it’s great that your processor seems to be running. Keep up the good work. Some things take forever to figure out. Just keep at it.
