So I made a few new accounts and bought some stuff's from Amazon but because I know that all the stuff's are crap I will asking Amazon for refund. So that way you get something and I have my money back. Deal? Hahaha
Good Video. Thanks for the Lawnmowerman reference.
Yeah that website is very very helpful, we keep it bookmarked!
Thank you for this 25 min.... i wish the two of you a wonderful weekend.
Thank you Peter, we appreciate you hanging out with us :) See you on the next video!
Another classic saved! I’ve always loved the speed up hack.
Thanks Hammer Billy Lee, we appreciate you hanging out with us a little bit!
Your troubleshooting skills are impressive
Thanks Jason we appreciate you watching!
Thank you for filming this, I really enjoy it! I repair a lot of retro computers and occasionally arcade PCBs, and... "It's always the logic chips!" seems to be a common response. Those logic chips seem to be very prone to failure, and I haven't quite figured out why!
It depends on how you look at it, this one lasted 40 years! That's not bad :) Thank you for watching Douglas, we appreciate it!
Hmm when the logic chips going insane..
. And the known universe following crazy news rules.
Nice fix! Plus it’s got the speed up hack which makes it so much more fun.
Thanks BulkSlash, we appreciate you watching!
"Bring in the logic probe!" - Sark, Tron
I always remember that line. Classic movie!
Dillenger......end of line...
I totally enjoyed this video and Trevor was awesome to watch hehe. Keep it up Ron and Joe!
Trevor's a real character! Thanks for watching Gabz we appreciate that.
Nice clean fix...cheers !
Thanks andymouse123 we appreciate you spending some time with us :)
Some time ago i bought a box of "assorted arcade boards" with at least 12 arcade boards i bought myself a logic probe and a soldering station to try out if i can manage to fix the boards that don't work , most of them appears to be bootlegs but ive spotted a dragon ninja and a double dragon boards, it will be fun to try to identify wich games are the other ones
That's pretty cool man, you might be able to google some of the markings on the boards to figure out what they are or use 'romident'....
That was great repair on board and quick also 😆
Oh no I want a Pac-Man now! Nice fix!
It's pretty cool :) Thanks for watching James!
That PCB brings back memories. Back in the mid 1980’s, I accidentally destroyed a Pac Man PCB with Wendy’s BBQ sauce. To date, I think believe I’m the only person I know who can say I destroyed a video game with hamburger condiments.
challenge accepted
“Honey, don’t ya know? I’m more than Pac-Man with a bow!”
If that means a weird jumble of pixels, then she’s not wrong
We got it straightened out :)
Good work ron oh billy billy billy
Thanks 43 delta bravo 666 we appreciate you watching :)
Nice repair, but damn that's a fast Pacman.
I wonder if there are different speeds of the speedup chip? This one was ridiculously fast!
Nice video and not a Fluke 9010 whatever in sight. Enjoyed the play part too... good stuff.
I like to fix things with the minimum amount of tools, it's easier to understand and cheaper to do for the home hobbyist who might find a game somewhere and want to fix it themselves... I know a lot of folks have a more extended test bench but I don't know the knowledge or the desire really to get elite level, I want to keep it as simple as possible which I feel helps more people fix theirs that watch. My goal is to keep as many of these games (and other electronics too) out of the landfill as possible.
@@LyonsArcade I think that's great. so much more accessible for us mere mortals
Thanks . and Greetings from Poland ( I have some Arcade game PCB and will run it ;) )
I had a Ms. Pacman arcade cabinet, but about 20 or so years ago, it stopped working. I like to joke that it got Y2KO'ed.
If they don't believe that, just tell them you were so good it couldn't handle it.
@@LyonsArcade I would like to fix it someday (if that's possible), and I would like to get a Pacman arcade board and learn how to swap boards.
Great video as always!
Thanks mike we appreciate you hanging out with us for awhile and watching :)
This dude can Pac boi.
Great work mate. I got to get me arcade game or three!!
It's pretty easy when the game is that fast. PACMAN in my opinion is more difficult. Thanks for the info
That PCB looks like the stuff of nightmares. I don't know how you can work on them like you do.
They look more complicated than they are, you can break them down into sections and move right through them.
ah excellent, my favourite type of video..thank you very much! I appreciate when you probe some logic.
Thank you for watching 808v1 :)
The game we all cut our teeth on
And what a great one!
I've got a Ms Pac-Man board that plays perfectly fine, but the sound is distorted. Looking at the 74LS174 @ 1L now. Thanks for pointing me to lawnmowerman's page!
lawnmowerman, IS THE MAN.
So you get only half the points if everything is in half. Hahaha VERY UNIQUE GAME. Don't mess with the 4D pin unless you want sprites cut down to 1/4th. Hahaha
LOL That makes sense!
I'm beginning to worry Ron, have those ghosts held you captive, it's been 3 days buddy 🤣
Tuesdays and Fridays :) Thanks for watching Mike we appreciate it!
I'd be interested in seeing the A-Team Van but my question which one? The most recent one.
Trevor is a child of 80's, the only A-Team van he's aware of is the one on the original show :)
Great video but I'd do better without the sped up chip. But it's still cool seeing it with the sped up chip. I think you said a faster sped up chip can be installed-wow. Unless someday I get an arcade Ms.Pacman or the table top one, I'll keep enjoying the gBa advance sp version. Fun video!
Yeah I think they made different speeds, I think there's a number you change in the code and depending on what number you change it to it changes the speed. The GBA version is very cool, we get that in all the time in our store!
Did you know we have a new channel? It's called "My Brother Donnie" and is at the moment following his and my attempt to rehab a mobile home that was completely destroyed! Check it out @ ruclips.net/channel/UCuDDNTFs-BLcNYq4DO-BYYA
I checked for ATCS on the train track that runs through your town. The line is called the R Line from Charlotte to Savannah, I believe, and there is only ATCS where the line goes through Columbia SC. There is a crossover there and they have ATCS on the air and there is a server feeding the data from those control points.
It would show you when a train was heading north out of Columbia SC
I have to check the North end of the line and see if in CLT there is coverage
The line from Columbia through your town uses ABS ( Automatic Block Signals ) so there is nothing ATCS being transmitted for that segment.
Looking at Google Earth I see they did install new block signals, but no ATCS
I am in the same boat here in Pennsylvania
The Reading Line has aaTCS out of Reading to West Laurel, then ABS all the way to the yard in Hellertown, even though there are control points on the line, they are not on the air.
Is that something they're going to eventually add, or is it outdated and they likely won't do it?
@@LyonsArcade They did improvement on the line, so I don't think they will add it, but, if CLT has coverage for the line at the North end, you can run 2 displays, 1 showing CLT and 1 showing Columbia and that way you would see when a train was coming north and coming south
Joes Classic, I always thought that you were Joe? there must be another owner named Joe. I want that logic probe in your hand more often. I wish you did more arcade repairs like this I really like these a lot. And I like your EM troubleshooting with the schematics because those EM switches gets confused how they logically thought about the sequencing of the switches.
Joe is my brother, he fixes a lot of the games but works first shift, I come in later and film most of the videos after he leaves, I'm Ron. Yeah the EM schematics are my favorite, it's like a Sherlock Holmes puzzle, you have to figure out what's going on with the evidence you find :)
is it Joe that makes the videos or is it you Ron that makes all the videso and goes over the EM schematics. All this time I thought it was joe I was talking to.I didn't know you guys had that arcade bench setup I don't think I have seen you guys use it much in the videos
Menuda máquina....33770 que bueno...👍nice
Thank you Carboumen! We appreciate you watching man !
What about player 2 flip?
I forgot to test it on the bench, but in the cabinet it worked... so I'm not sure if that was fixed by the same IC or if it was just an issue with my test bench....
Love me some Ms. Pacman! Well done! Did that fix the cocktail flip-mode?
The SPEED UP chip is installed
Yes, it is!
Dat board swap tho :D
He's an expert.
Great video one of my fav's, I got a great hacked version that makes the game alot harder, I should post a video of it.
Yes sir, you should! I've seen some of the modded ones before, pretty fun stuff :)
I have a Ms.Pacman machine and I power it on but I just get a “ free play” screen, if I hit one player and move the joystick you can hear the Pac-Man moving but I can’t see anything. Can you please help me fix this?
Yes Stacy, reach in the door and look on the left or right frame of the door and see if there's a little black button, it sounds like you're probably in test mode, you slide the button the other way and it'll take it out of test.
Holy smokes I remember when you only had about 500 subs
Slow and steady wins the race :)
I played the atari 2600 version of pac man and was good
I liked it when I was a kid, I wasn't smart enough to know it was horrible and I wasn't having fun.
So I am certainly going to look at that website, but I recently purchased a Ms Pac-Man cocktail table. All original, I believe, with the ribbon, not modified, Bally's Midway 1981. It comes with Pac-Man / Ms Pac-Man manual so, it's all legit. The problem I'm having is Ms Pac-Man will bite a ghost and totally glitch out and show like a Tron grid (as my 12 yr old daughter calls it) and go back to the main menu where it says one or two player. If anyone can help out, any insight would be greatly appreciated. I'm a handyman that can fix anything in your house, but when it comes to electronics, I'm pretty much completely in the dark. Great video, you're the first light at the end of the tunnel I have found in dealing with this problem. And it doesn't glitch out all the time, but it'll go on these streaks where you can barely get through a few boards and it will glitch. Nite: Also I don't fully trust myself not to mess this up, so if anyone reading this who knows how to fix this stuff is anywhere around New Orleans let me know. I'm an hour outside of town and would gladly pay somebody for the testing and fix of our cocktail table Miss Pac-Man issue stated above. Hard to find people who work on this stuff anymore.
do you know where i can find a crt back board that attaches to the back of the tube that pulls off? i just got one and that board is cracked
You can solder it back together with jumper wires and cap legs if you want, or if you know which monitor board it is you can buy a used one off somebody on www.KLOV.com , sign up for the forums over there and they can help you (I'm on there too) Killer List Of Videogames
Holy split personality
We got it back together again :)
Thanks for this man! Is there another way to know if the leads are supposed to be high, low or pulsing aside from comparing another identical chip on the board? It doesn't look like it's on the schims.
Yes, if you gain an understanding of the circuit and what they're trying to accomplish, and then an understanding of the particular IC, you can know which it should be doing. So if for instance it's a buffer chip, the input mirrors the output, so your knowledge of that chip would inform you that the input and the output should look very similar (low/low, high/high, or pulse/pulse)... if a chip is inverting a signal, they should look opposite, etc. Once you work on several you start to understand the relationship between the chips, so what they're trying to accomplish with the ram/rom/etc. and it helps you know which ones should be active and which shouldn't. It kind of comes with time...
@@LyonsArcade That makes sense! Thanks!
I have a lot of IT and electronics background (Guitar technician so lots of pots and caps etc) so I totally get what you mean...but haven't gotten much into the chips and logic end of it things. I have a friend giving (yeah!) me an outrun to get rolling on soon so I'm so stoked.
Is the logic probe becoming a main cast member on the channel? Time will tell.
Soon we will begin using an Oscilloscope, at almost no benefit to the time or effectiveness of the repairs :)
my board works perfectly i just have slight geometry issues any ideas?
on the far right of the screen it slightly curves upward
Usually that is the horizontal sync on the monitor itself. Adjust the horizontal sync or horizontal frequency on the monitor until it lines up for you, if it won't line up usually the monitor needs the capacitors replaced...
@@LyonsArcade the monitor is a brand new alienware hdmi gaming monitor lol
other boards work fine on the supergun setup
PCB son los "cartuchos" del arcade?
Does anyone know about a repair service for these motherboards?
Arcade forever (ºV) pacman
Thank you for watching Wilder9777! Pac Pac Pac Pac Pac Pac Pac Pac Pac
"I'm not all that great." I'd disagree!
Thanks Trey, we appreciate it!
there's a hack in Pac-Man within the game just goggle or use youtube to find the dead zones you can stay in that one spot and the ghosts don't go in that area that's why you see scores like 450000
My screen is moving rapidly across monitor please help
Now, that TMNT cabinet with Turtles in Time---is that the one from Arcade1up, or is it an original cabinet?
Nothing we have is an Arcade1up, they're about half the size of a real one
@@LyonsArcade I asked because I have the Arcade1up version, and it's got both games.
Can the player choose which of the two games to play, or is it necessary to modify the inside of the TMNT cabinet to switch games?
👍👍👍

Can you please give your opinion. I have a 1981 MsPacMan arcade console. It's getting old, should I disconnect the power when it's just standing there, or better to let it run. I worry about wearing out the picture tube ect. Thanks Teri
Keep on rockin' in the free world
Hey, Joe..... I was a pacman king back in the day, and the arcade was losing so much money when i played, (me and a black cop named Roscoe would tie up the game for hours...) that they finally ordered a new set of ROM's. i believe they were called "PUC 2". It had mazes with exits at the top and bottom, and mazes that were invisible. one maze, you could go inside the maze walls, but the ghosts could not. I have not been able to find any one who has seem these ROM's, or knows where to get them. I now own an original PacMan board, and would like to find a set of these ROM's, if possible. any ideas?
Rusty that name may have been what that particular 'kit' was called but sometimes there were other kits that were the same thing, but with a different name. There's a kit you can get with 96 different versions of Pac-Man on it, i'll bet one of those is the one you played... check it out here: ruclips.net/video/XDauEYaCUg8/видео.html
I would think a messed up ROM or RAM chip
Seems to be affecting every character. One of the address line pins not connected right, so re-reading the same locations multiple times. Although interestingly not affecting the bottom of the screen and the cherry.
If it's a rom chip usually you'll have the entire image missing, if it's a ram chip usually you'll have extra parts (lines, dots) in weird places.... if it's the right image, or the wrong image, or split in half nad doubled, etc. it's usually a chip that addresses the rom....
When the circuit board is plugged in and running how come no one gets shocked by it?
It's because the voltage is so low on the circuit board... it's running at 5 volts DC which is considered 'low voltage', it's the same voltage like a USB power cord runs at... so if you plug a USB cable into your computer then mess with the other end (or a lightning cable for an Iphone) it's the same 5volts DC, just not enough there to break the resistance of your skin and shock you....
Oh..it's sort of like when I touch to pinball machines.
When there not grounded right
I get a slight buzz or vibration?
I don't that's the right word.
I mean it's not painful or concerning.
More like zzzzzz.
Well that's kinda neat.
Zzzz cool.
CRT
The only way to fly!
It appears to be the fast version, which I hate.
Ok, do you like anything, or did you just want to mention what you hate?
@@LyonsArcade In case I didn't make myself clear, I love Ms. Pacman and think it is one of the greatest games ever. However, the fast version ruins the gameplay. Furthermore, it is a scam because people make more mistakes when it is moving that fast.
Do you repair. I have 2
What are you doing? You're supposed to be up against the clock because the customer is on the way right now, but the problem is still so elusive that you aren't sure you're going to make it (even if it really is an easy fix), and of course you're supposed to have arguments with co-workers and equipment breaking down. This is so anti-climactic. You'll never get that gig on Discovery at this rate.
Im looking for a ms pac man broad. I have jr pacman cocktail table and the sound isnt possessing right. Its a chip I just don't know enough to find the chip but i got the broad out looking at it. But I want make muchine a ms pac man cocktail now. Im looking a for a broad for my muchine
Awesome work, if you want to see other great 12 volt videos please check us out.
