[@Inject0r]

Joe's Classic Video Games this fix was very nice and all, but won’t the cabinet be back within a couple of months or so, due to the resistance on the ground lead of the edge connector? There must be a reason why it got so hot, right? (Or am I missing something here?) Other than that, really nice video and great troubleshooting!

[@evergriven7402]

Thanks for the video ... A couple questions please : where did you get the pins for the Jamma connector any online links ? what kind of monitor was that k7000? or mitsushita?

[@stephenlongsmovieandvideog9283]

I think it's a Matsushita

[@ArtStoneUS]

Dig dug plush toy is no longer available on Amazon 😭

[@jaybrooks1098]

Since there isn’t any masking the tin becomes a sacrificial metal because of the two different metals and current. This will eat away at the traces till there isn’t any. Using dielectric grease will probably prevent the issue since it will prevent moisture from forming electrolyte.

Who doesn't love digdug? It's still fun even after like 40 years.

Fixing a game is always satisfying, but can get really frustrating depending on who got to it before you did LOL. Atari games are pretty well built and easy to work on. And they also weigh a ton compared to other 19" games.

[@LyonsArcade]

Ain't that the truth!

[@simonmanners4108]

I have to confess I did something wrong the other day. I watched a KZbin video about a gentleman showing how to wash a rope. I thought “well I could do that and maybe get something right”. I was sceptical though because the comments where full of howls of indignation about how he was doing it all wrong. So I tried to wash my rope using the generous information provided in the video. To my dismay it came out clean, I must have gotten it all wrong because according to all the expert comments it was done all wrong.

[@LyonsArcade]

LOL I hate it when that happens!

[@kh40yr]

I miss this game. My god. Untold fortunes put thru the one in town back in the day. All I had,,right into the machine. The good old days. Nice work Joe.

[@vashstampede5933]

While I own a *cough* Arcade1up version of this, it is one of my favorite arcade games of all time and a timeless piece of art just with the cab artwork itself. Great analysis and repair work Joe, it's great to see this great old game roar back to life, IMHO it deserves no less. I pray it too will forever be preserved for future generations to enjoy and experience as we did growing up. Thanks for sharing this!

Back when I worked for a company that made Atari peripherals we used those machine-pin sockets (Augat was the brand we used) instead of the cheaper variety...they just made better connections with the legs on the chips. Great vid...using the logic probe brings back memories of troubleshooting circuits in my college electronics classes so many years ago

The jamma connectors always overheated and burned on the 5 volt line to the logic board. We used to rebuild the jamma connectors. I worked for AMERICAN Amusement and Vending Corp out of Bay City MI. for 4 years. I did both bench work and field repair I was their monitor expert being a tv service tech prior to working in the coin op industry. Juke boxes were my favorite things to work on. The Rowe cd jukeboxes had problems with their early CD player units. We replaced the upgraded version CD players and never had trouble afterwards

[@SteveJones172pilot]

Great video.. I had a similar problem on another machine - I think it was a PacMan, where the output of a chip was stuck low, and it turned out to be that it was really the INPUT of the chip it was feeding was stuck low, which wouldn't let the output rise.. The hint in my situation was that because the OUTPUT was being held low, it was causing that chip to sink as much current as it could, so the WORKING chip got really hot, and when I followed that output to the next input and replaced that chip all was well. I hope that makes sense. Great video. Definitely subscribed and will be looking for more of your stuff

[@LyonsArcade]

Thank you for watching it’s really fun to track these down!

Here's a tip when trying to measure resistors like you were doing with the volume pot. Learn to hold chopsticks. You can easily connect to both terminals and still hold the component.

[@LyonsArcade]

So you're saying, I can press it each time, too then?

[@DeviatingVapors]

might have a built in repeat rate value, (like Tempest) but in this game pump recycle times are crucial to survival... owned a decent cocktail version of this, but never got very good at it. always kicks my ass - as it was designed to do. still addictive. still on my build list as I need an upright version, control panel parts in storage.

Funny when we were kids of the 80's going to arcades waiting for the next greatest Video game to come to your local haunt. Not once did we revel over the artwork on the cabs. We were more interested on what was on screen.... But now as we grown old, we start to apriciate the work into the art and presentation of the cabs. But also the half the problem was that you would have 10-20 cabs pushed together a row and would never see side artwork anyway.

[@LyonsArcade]

Yeah that's weird how that works like that. I was the same way when I was a kid I don't remember what most of them looked like... maybe I was seeing the sideart as a subconscious thing though and it made me spend more money... like you said though, people come in our shop all the time, they want games in mint condition, I've tried to tell them they were never in mint condition but they want to live the illusion :)

7:40 Pink rubber eraser from a pencil. Takes off the tarnish/oxidation without damaging the trace. I did the same thing when I restored my friend's Simpsons game. It works for all PCBs, gold plated or otherwise. There, I ruined your magic.

[@LyonsArcade]

I didn't say it, now you'll have to deal with people telling you that erasers damage the traces because they have some crap in it that's acidic. At least that's what people complained to me :)

[@Sun-ut9gr]

@@LyonsArcade I've never heard of erasers being acidic, so I had to check. Per the SDS for PaperMate's pink eraser and their wood pencil lines, there are no harmful compounds or chemical incompatibilities known. www.sprproductinformation.com/SDS/SAN/PMPinkPearl_70527.pdf www.officedepot.com/pdf/msds/929661.pdf Whoever told you that was probably using something other than pink eraser. There are rubberized abrasives available that may be detrimental to PCBs, but I've used Cratex as well with no issues.

Yeah me neither, I felt pretty sure it was really late in the amplification but you know what happens when you assume!

[@Dark_eVader]

@@LyonsArcade Yeah my crutch is that I almost always assume. :D

[@DeviatingVapors]

thanks for going thru the schematics and such. a few tips for this game maybe only found in the operating manual - more points are gained by the color coded dirt, as well as how many enemies can be squished in the same column with a single rock. pumping vertical or horizontal changes the point structure of popping them (my friend will start in one direction, then maneuver to the other to pop them). so of course he kicks my ass at this game, and has incredible reflexes on the pump button. the bonus fruit only comes when ... there are two or more enemies. enough rocks have to be dropped before it will appear tho. when there is only one left, then it exits to the top left corner. never considered staying at the top. wonder if I could last longer at the higher levels longer...

[@rlgrlg-oh6cc]

The one LM324 is set up for a gain of -1. So the two speakers are wired in series between the two amplifier outputs, and through the one wire-wound volume control. When one amplifier output is going positive, the other is going negative.

I was able to repair my Centipede machine by using copper tape as you did in this video. You must have shown that in some of your previous videos because I always check your channel as reference whenever I'm doing any repairs.I have always used an ink eraser to clean the fingers on edge connectors, and it always seems to do the trick but I'd like to know your secret for cleaning edge connectors. My next project in on my Midway "Space Invaders" machine. I'm missing a few sounds. If my memory serves me correctly, when the saucer flies across the screen the saucer sound is different than what it should be. Also, there is no sound when I hit the invaders. I get sound when I shoot, I just get no sound when they are hit.

[@LyonsArcade]

When you do your space Invaders, you've probably looked into it already but there are a bunch of LM3900 chips on the soundboard that if they go bad it kills certain sounds, you can look on the schematics and see which chip makes which sound. Replace that chip and it will likely fix your missing sounds, I believe we did a video on here a long time ago showing how to do it. One caveat though, the "Invader hit" sound you're missing, if you look on the Space Invaders schematics, there's a typo where the wrong place is referred to as the Invader Hit area. So if you use Space Invaders Deluxe schematics, they fixed it and the area they say is the Invader Hit sound is correct. If you pull up both sets of schematics you'll see what I'm talking about.... thanks for watching B L, we appreciate it and good job on your Centipede :)

[@vince_martyn]

When you said 11H was running off the 5v rail, it isn't. It's running off the 10v unreg rail and the 5v rail is being used as a nominal mid-rail for the audio. Pins 10 and 12 of that chip go to 5v for that reason as a reference, they are not being loaded. This is an alternative to running the opamp from a split power rail (e.g. +12 and -12v) and in that world, pins 10&12 would be referenced to 0v. So the audio output from 11H will be biased to 5v and swing above and below this in sympathy with the audio signal. Love your videos and channel. Getting a pinball machine of our own soon.

[@LyonsArcade]

Nothing says quality workmanship like seeing 1/2 dozen wire nuts splicing a wiring harness together, along with tack soldering.

[@a.fritzbecker8986]

Also the "thing" that moves around on the rheostat, that is connected to the center terminal, is normally called a "wiper', you were probably just tongue tied or had a mental block and knew that anyhow. It's sort of weird to use a linear wire wound rheostat as a volume control, but I guess they needed the wattage in that circuit, too bad they didn't have a screwdriver slot cut into the end of the shaft. The original rheostat looks like it must have been 5-10 Watts, the little carbon pot is maybe 1/2 Watt, and had no business being there.

13:25 - Machined pin sockets are the ONLY kind I will use in all of my electronics. The stamped pin sockets are just as crappy as the Molex edge connectors, just like the one you had to rebuild at the beginning. With the stamped pin sockets, over time with temperature cycling, the chips literally climb up and fall out of the sockets. I call those, designed in breakdowns.

I have seen a ton of games where the roms have raised up out of the sockets, you're absolutely right!

[@douro20]

Do I see two 51xx chips on there? Those are microcontrollers from what I understand, and they handle the I/O. JROK makes a replacement which uses an ATmega chip. The closest equivalent to that rheostat currently being made is the Ohmite RES50RE which costs US$56 and has a standard lead time of 23 weeks if they aren't available immediately.

[@atomicskull6405]

With these Namco licensed games did Atari use Namco made boards or did they manufacture the boards for the Us versions themselves?

[@LyonsArcade]

Atari manufactured pretty much everything in the game, remember they were using the Atari power supply design and they had full production capabilities for the games they designed themselves, like Asteroids, Gauntlet, etc. At the time, The industry was so huge that there were several production facilities needed to supply each market with games, so Namco was making it's own boards overseas and at the exact same time Atari was making it's own boards in America.... The Namco made boards often were very different designs. A game like Dig Dug though had several board revisions as well, they sold a ton of these things.

Make the music stop! Please! 😄 The trick to getting points is to drop the rock on the monster while it's frozen because you pumped it up. Multiple monsters with the same rock to score really big. You can part way inflate the monster and then let go, to get all of them together in a big bunch

[@LyonsArcade]

I've seen that a few times in the attract mode but I just like to play it digging through the ground a little bit :)

[@charlesmurphy1510]

If you cut a shallow notch where you wrap the trace then the tape won’t move around. Or just use contact cement.

[@LyonsArcade]

Thanks for the tip Charles!

[@kakurerud7516]

hold button down to pump ; ) one of my all time fave games. got the mini one from wallys tho close its not the same.

[@LyonsArcade]

One of the coolest early 80's games for sure!

JOE'S CLASSIC VIDEO GAME, any reasons why arcade games use a rheostat instead of a potentiometer? and why is the rheostat 10watts to 50watts depending on the arcade games amplifier?

[@LyonsArcade]

They're the same a Rheostat is just made differently so when it needs a lot of wattage sometimes the Rheostat is cheaper to purchase than a potentiometer. The reason it needs to be more wattage is because where it's placed in this design is after the music has been amplified.

[@billwilliams6338]

@@LyonsArcade do you know why they would want to place the music volume after the music has been amplified because you would need to use a high wattage rheostat instead of using a normal low wattage potentiometer? I don't see the advantage but I think I have read because they had to run the harness wires all the way up to the front of the arcade enclosure which picked up to much noise.

[@vk3hau]

bill williams becouse if you control the volume with the preamp you can induce noise artefacts and static before the amp, controlling volume after amplification limits hum and noise artefacts been induced . think of it this way, you turn the volume right down on the control before the preamp, but noise artefacts level will still be at the some volume level. where as, if you bring the game sounds above the noise artefacts level at preamp stage, then amplify the games sounds, and then control with the " volume control after amp " which is above the noise artefacts level you will less likely here any noise Artefacts.

[@billwilliams6338]

@@vk3hau but where are the noise artifacts coming from if you used the volume control BEFORE the preamp? they can just use "shielded" wire to run the volume control to the front of the arcade cabinet. The Shielded wire will shield out the noises

[@vk3hau]

bill williams No, just No... it doesn't work that way, way more effective to reduce the SNR on the preAmp and Control the volume at the Amp.

Is the monitor on the dig dug a Matsushita or a GO7

[@LyonsArcade]

That one had a G07 in it!

[@KMKTO]

Have you’ve ever seen a tron arcade cabinet. If so do you have any videos I could possibly watch you have made on the arcade tron? Also I subscribed to your channel because it shows me some basics of how arcade machines function.

[@LyonsArcade]

AJ Thank you for subscribing! We have had several Tron machines but I haven't had one in a while, if I get one in I will film it for you.... we weren't making videos the last time I had one in!

[@KMKTO]

@@LyonsArcade Thanks for everything I think your one of the best arcade KZbinrs I’ve ever seen

Thank you for watching!

[@AzrialAlaria]

There is a retrocade about 5 mins away from me that has one of these units in good condition as well! I like the Dragon (Fygar) in the game!.....as you may have guessed lol.

[@LyonsArcade]

You do seem to have a touch of the Dragon appreciation there

[@AzrialAlaria]

@@LyonsArcade Indeed! Lol

Did Dug was the first game I bought for myself on my Intellivision. I used my Christmas money and in January of 1986 I paid $38.00 at KB Toys...

[@jankro1]

I have successfully used fiberglass brush to clean connector traces.

[@LyonsArcade]

I've been trying to use it more, somebody sent me one! Thanks for watching Jan!

[@jussikuusela7345]

My first touch to Dig Dug was on the C64 as late as 90's on a turbo tape. Liked it instantly. Then... one of my favorites is Wizball, but I bet there is no arcade conversion.

[@anthonydenn4345]

Atari 2600 is my memory of it, great game.

[@user-sh9du2nv5y]

Good job figuring out the problem but I wish you would have showed us the chip that you were having problems with and which leg it was that was generating the problem with the sound

[@LyonsArcade]

No matter what I do people complain I didn't do it right so you'll just have to be happy with the little bit I did, sorry I didn't show you every thing you wanted to see

[@user-sh9du2nv5y]

@@LyonsArcade it's not that you didn't do it right, I think you missed a important part you left out and that is showing the component that was causing the sound problem. I think if you watch the video you made you will see that , nothing wrong with making a mistake you can always fix it and edit it in, this way you will be making better repair videos to show here.

[@johnketterman5700]

My favorite game, some day I have the arcade version
