With your nice artwork on the top too :)
@@LyonsArcade Nope.
@@LyonsArcade Thanks Ron. I love watching your repairs and glad to be able to help just a tad in your restoration.
ECL was used for the sprite memory simply because it was extremely fast. It allowed for very high resolution animated sprites, a feature which really set Nintendo apart at the time. Perhaps one of the best known examples of this is the tiny explosions in Mario Bros.
That makes sense thank you Douro
ECL = Emitter-Coupled Logic. This type of hardware was usually used for specialized applications like radio-frequency counters or RF synthesizers. It was fast, but quite power hungry.
Fun fact: this is the first game where that character is named Mario. In Donkey Kong, he was known only as Jumpman.
This is true
It’s nice to see you restoring the old video games the new generation don’t appreciate the old video games. They’re all about high definition keep up the good work, Joe.
Interesting bit near the end where you talk about the noisy arcade experience and how some games might have there own bit of odd noise. I think you nailed it when you mention people who have home games and they are worried about a problem that isn't really a problem. Just crank up the tunes and sip on a pop people!
There's two sides to it. Some people are worried about it because they think it's a problem, other people are worried about it because they're perfectionists and it drives them crazy :)
Thank you for watching as always Paul!
Lovely job. Those 80s arcade games were pretty unforgiving but so addictive.
Yeah, they had a different purpose, they had to make it fun but they also wanted to make that quarter :) New games for home play don't need you to spend another quarter so there's a slightly different design :)
I had no idea Jr came out a year after Donkey Kong. They made a lot of upgrades to that game. I totally suck at this game. It seems like they made you magnetic to the bad guys. They instantly go where you are. If you make it to the 3rd screen it becomes nearly impossible. This game just ate my quarters, I am epic levels of shit at this game. Nice work as always.
Took me 20 quarters (if the game hadn't been on free play) just to get to the upper right part of the screen on level 1. Not even talking about getting to the top left. And that glitchy jump there. But I got pretty good at this game, I can sometimes beat the second level 2 (when they have double the birds) and the second level 3 (our machine has the level order 1-4-1-2-4-1-3-4-1-2-3-4), but not often. Only once I could just barely get a 1 for the leftmost digit of the high score (after playing it for like 6 years!)
Aren't we all buddy... aren't we all. 😊
Another legendary machine up and running for future generations to enjoy as intended in it's original state. Great job yet again. 😎👍
I'm pretty good at removing chips....
Out of the bag and into my mouth watching your vids! 😅
Another great one Ron 👍
hahahaha Hey Jabo how you doing man? Thanks for watching
Hanging in there. Hope you guys are well!
Its funny. The number of video games I forgotten I played. But all of a sudden that you start humming that game music from memory and realised that you must thrown a ton of coins at it in the 80's. Good stuff saving this old classic. 👍👍👍👍
There's a Clint Black song with a line "Ain't It Funny How A Melody Can Bring Back A Memory" .... ruclips.net/video/qgIfUfMQSOs/видео.html
This thing was looking rough and left for dead and now it looks and plays great! Another one saved and great job as always Joe and Ron. 😃 Now people can have fun for years to come. You were so close on that one game and they got ya and made you redo the whole level 😜 But boy is it addicting because I know you can beat 'em on that next quarter! (least that was what I always thought but was never that good BUT I HAD FUN!!!!) 😅
I followed your links to get the solder sucker. I can agree, it's excellent and recommended.
I would never lie, to make you buy :)
It's 1982 again! Fantastic memories.
You know something if we throw out game that are broken there would be none left to enjoy after being repaired.
Ronnie, thanks for bringing another one back to life! Great video. PS. Donnie is funny as hell. We traded a few responses on a video, and he's got a great sense of humor! ✌️
He's a very unique person, that's why we made the channel so more people could meet him. He's funny, thinks different, works hard, always has interesting ideas and scenarios going on.
Wow, we have come such a long way in 41 years. Even the NES was quite a bit more advanced than a lot of those super early arcade boards from the 70's to 1982. I just cleaned up my NES the other day, and all of the chips are already crammed in much closer than the arcade board here, which says a ton about how fast things have been advancing, but at the same time, it's wonderful to pay homage to, and keep the classics alive!!
Played the original Mario Bros. arcade, and watched someone play Donkey Kong Jr. across that part of the arcade place! Both excellent games!
EDIT: I'm with you about the arcade form factor; what matters is that you get to play it, and what if you want to play sitting down? I'd actually give my feet a break at times, and I'd pull up a high chair for arcade games with a nice special beer from the Free Play arcade place, and I saw a couple of machines like the one you worked on while I was there!
Ron, you're a good man. Don't let anyone hurt your feelings about how you play the game. You do things in one day that most of us could never do. It always helps my mood to watch your videos. It's therapy for me, and I notice it is for others, too. All good wishes.
Ron, I think it's great that you are not only knowledgeable on how to fix these machines, but you enjoy playing them. Too many of the guys back in the day had no interest in playing them. Who cares if you are not a pro at all games. Get a life people!
Impressive that old hardware CAN still be fixed with careful work.
Watching you troubleshoot this stuff is like pure wizardry to me Mr. Ron. Good job.
Hi Ron. Thanks for getting it back to life. All looking great now and playing well. Big👍
You got this looking so good. Beween Joe and yourself, you've got a great little machine that would look amazing in a collection, even look amazing back in site in a retro arcade. Great work. :)
Thank you Brendan!
I’ve had many great screwdriver chip pullers. I got yours (following your Amazon link) Your puller is way better. Been trying to use your link for all my Amazon purchases!
Thank you Geeteoh! It's amazing that the thing is actually better than a screwdriver!
I just know with the cocktail cabinet I'd wind up leaning over it for a couple hours and kill my back. Worth the sacrifice to play a Donkey Kong arcade game again.
It looks great and the sound has so much 'oomph'. Nice one!
CRTs are great! Cocktails are great! JR is great! This style of cocktail ('Japan' style? 'Invaders' style? Compared to Midway, I guess?) is fun and I think worked a lot better as a table. I'm pretty sure we had a Mrs. Pacman in a unit like this at a sub shop in the 80's. It took the place of a regular booth's table. The regular Pacman cocktail really wouldn't have worked for that. Anyway, this is great. Loved the trouble shooting.
forty-one. looks so much nicer with restoration to the table. these cocktail table things shouldn't really be an outdoor thing. probably poorly stored for a long while.
Yeah unfortunately they're big and once they break, people stash them where they can...
You are terrible at this game :D
Such a beautiful restore! Is one of my favourite games, just close behind the original DK. Spent an absolute fortune as a kid on both those games lol.
Thanks for all the great videos Ron and keep up the good work.
My neighbor down the street had the upright version of Donkey Kong Jr.
Nice video. Restoration well done. Very much worth the effort.
Thanks Ron! Great to see another original brought back to service :D. I'm not the best judge but seemed to me some pretty good gameplay shown there. IMO.
So awesome!! Saving culture one game at a time.
The monitor looks great. Awesome job!
Thank you AC_Cobra14 !
Greetings from England, love the work you guys do, I’m a big fan of these classic arcade games. It does make me wonder though how these machines ever paid for themselves at a quarter a pop. The outlay must have been relatively large and they would need to be in play all day to break even or make a profit. Then there’s the electric and other overheads and maintenance. A bit like the automated car washes, cost a fortune and never made money. Much cheaper to pay kids a few bucks an hour.
That's the dirty little secret, I don't think most of them made money at all. They split the money in half with the location, so the operator had to make twice what the game cost a quarter at a time just to break even. Some games like Pac-Man, Galaga, Space Invaders, Defender definitely made good money but your average game probably struggled to ever even pay for itself, much less for the operator to travel around working on them and collecting them.
@@LyonsArcade thanks for the reply. In the UK back in the 80s a lot of the free standing machines were in pubs or pool halls, In fact even fast food take away shops would have a machine buzzing away in a corner, most with some completely unfathomable game that would quickly hoover up your money. before you worked out what you were supposed to do, Happy days! Keep up the great work.
I think the annoying noise that some people hear from the arcade machines is coming from the flyback transformer. My dad was part owner of a tv and appliance repair shop and I would hang out there a lot. I kept noticing that some of the tv’s would emit a high pitched squealing noise. I asked the tv repair guy what the noise was and he said, “what noise?” I was eventually able to pinpoint the coming from the flyback. As it turned out older folks couldn’t hear the noise. As we age our hearing degrades and we can no longer hear the full range of sounds that we could when we were young. 😢
I always found that game VERY challenging. I hope it finds a good home.
Great video JOE love them keep them coming 😊
huhuhuhuhh you're much better at fixing them than playing em huhuhuhuhuh... Joking aside great job as always, it's so cool to see others have the fun with these games like I did when younger and still do to this day! Thanks again for all you do Ronnie, great video as always! :)
That's what it's about, having fun. They're games! Thanks for watching Rep2369
@@LyonsArcade Amen to that Ronnie. I'm ofc of a mechanical background so I love the repair vids and troubleshooting aspects of your videos, but even better than that is just the joy which is so sincere, you and Joey having a good time fixing and playing games. That's what it's all about, big fan of the work and style of your videos, so happy I ran across your channel a few years back! :)
@@Rep2369 Thank you buddy, i'm glad you see it for what it is, we're just trying to be lighthearted if we can and have a good time, spread a little fun around.
@@LyonsArcade Thank you Ronnie, like I said I appreciate how genuine you are, you can just feel how you enjoy the games and what you do, when you enjoy what you do it's not work at all and things are done very well.I was lucky in that way also when I was able to work, I loved it and it never "felt" like work. You, Joey and Donnie are all great guys and a lot of fun to watch, I enjoy the videos on so many levels, keep up the great stuff my friend!! :)
I was at some guy's private arcade and he had a DK Jr where the sound ROM was missing. When I played the game, I also hummed the music the game should have made (and sometimes the missing sound effects) and he declared me insane 😛
Great job on getting this piece of history cocktail arcade game going again! Yeah I was never really good at Donkey Kong Jr. either. lol I am much better at Donkey Kong itself. I do have both 80's Nintendo Game & Watches of the tabletop and the smaller one of Donkey Kong Jr. They are pretty cool for what they are and are still fun!
The troubleshooting parts are fascinating, but the gameplay is the best part. Until I remember how much money I dumped into them back in the day.
I love this game! I used to play it all the time when DK wasn't available. I'm in GA and would love to have this in my basement...no matter what the haters might say! Just subscribed and I'm enjoying your vids and wish that I could do what you do so I coulds have my own collection. Funny thing, when I was a teen going to the arcades, when I grew up, I wanted to work on these and create them. Life is a cruel mistress! LOL
~That was a good one Sir!
The original DK became Cranky Kong and DKJR was his adopted son. DKJR had a son who is the current DK.
Some people watch Bob Ross paint to relax. I watch Joe’s classics repair video games 😏
Bob's the man!
What i usually do is piggyback a good ram chip on the suspect bad ram one before i de-solder it.. It has worked for me dozens & dozens of times
Thanks!
Thank you Dial Up Chronicles!
Your soldering skill is outstanding! I would highly discourage shorting pins! ECL is an old logic family that, if I recall correctly, was a lot more sensitive and faster than TTL. TTL was bullet proof. What CPU was in it? You mentioned sprites, which were used in the Commodore 64 which was a 6510
Z80. The CPU says nothing about sprites, the video chipset does these. Most arcade machines have their dedicated sprite hardware (think of a 74xx graveyard) There's arcade games from the late 1980s that have insane multi layer graphics with tons of huge sprites, all handled by one 8 bit CPU just because of the graphics hardware.
(btw. the chips he shorted pins were TTL - he didn't do it on the ECL ones)
It also helps they the monitor is digital. It's actually a CGA monitor so it uses TTL signaling for everything.
I won't sleep tonight knowing those naked eproms are out there somewhere. :) C'mon people! Probably have 'em on the dash driving around just to rub it in.
My favourite videos are the troubleshooting. That last issue fixed with voltage adjustment seems sketchy, like you might see it again some day. Seems timing or clock related that may have an analog component to it. But then I am on a comfy sofa.
I would like to see you using a scopemeter instead of the logic probe. Let's see the voltages and how sharp the edges are, maybe picking up more hints as you work through the problem.
This comment provided free of charge.
I'm a beginner and I make videos for beginners, we don't use scopes. If you give a beginner a scope, and then say "Here you go, that's MUCH better!" they don't know what to do with it, so it's useless advice. If you give a beginner a logic probe and say "it'll either be high, or low, or back and forth" that's something they can use and learn from. Oscilloscopes require a lot of training to even hook up, one of the main problems with teaching people is there is a huge barrier between the technical knowledge of the people who know how to design circuits and the average joe who's just trying to fix it. Oscilloscopes are way too technical for beginners and aren't needed, usually.
@@LyonsArcade I never got the impression you were a beginner making beginner videos. Seem pretty damn capable. I just figured you don't like change and prioritize getting results and earning a living. Lots of the EM troubleshooting you do going deep into schematic logic solving mysteries is quite compelling. I appreciate all the videos whatever y'all are doing but its the mysteries I love best. - 1/54,500
@@brainimplants Agreed. I wouldn't call these videos beginner videos, the EM repairs are top notch. I'd call them grassroots, as $100 will get you just about everything shown to get stated.
When it comes to removing solder, just like you would do at the cheap end is use de-soldering braid, not really that technical my friend. It's more with the DMM and Logic probe that may go over some heads, but even then... we all began to learn some where and from the bottom up, right? 😉😊
@23:31 Fujitsu 74LS74... No flip-floppy. Naught little things those.
Was it a flip-flop that wouldn't flip, or one that wouldn't flop?
Can't wait
The CPU was the Z80? A very venerable chip!
Only ones I ever saw in the wild were PAC-Man and Donkey Kong in the lobbies at some resteraunts. I played DK Jr while my Mom checked out at Alpha Beta (grocery store). That and Robotron 2084 were there. I’d run out of the two quarters before she got checked out and just stare at the attract mode.
Love this stuff.😅
We try to keep it entertaining
I like the game and I'm not hating. I just wasn't really good at it but I enjoyed watching people play it.
Awesome
Donkey Kong getting teabagged
That is a gorgeous monitor, the picture looks really sharp!
What dip switches did you have the game on? I know the DK games are hard but it seemed to be extra brutal! 😅
I didn't check... you could just chalk it up to i'm not very good at playing it, LOL
Hi fantastic video as always thank you. My question is can you possibly make a video showing how you remove the Pcb board chips your way this is something I struggle with somewhat thank you.
I used to play Donkey Kong junior on colecovision.
anyone know why the graphics glitches when the voltages is ABOVE 5vdc? Shorting out the data lines going to the RAM chips using a logic probe, how can you tell if the RAM chip is bad or good? I'm still confused why Nintendo used ECL RAM chips, they are faster access time but it seems that nintendo wanted to get more color data in and out of the RAM chips per clock cycle?
You changed the glass? That wasn't in the previous video!
It was in the part of the previous video that you didn't watch!
Hey Ron!!
great video!! Are those Pandora's Boxes in the background at 4:36??
They are!
@@LyonsArcade nice 😎
I was expecting to see a demonstration of the proper way to remove chips since you had mentioned needing the skillset a few times. Do you have a vid you can share on the best techniques?
I can't do a video actually showing any repair techniques, the neckbeards will just tell you and everybody else I'm doing it wrong. So I just give general advice, you're on your own to have one of the neckbeards show you how to do it correctly
@@LyonsArcade Sounds like an opportunity to elevate yourself above the "neckbeards" and actually teach some newbs a valuable skill, but you do you.
I wouldn’t be surprised if those ram chips died because of all the heat those arcade systems do produce over the years,now if there were heating conductors put on those ram chips along with a fan, that generated heat would,ve be reduced by aloooot.
You guys always do a great job no matter the project. 5 stars 👍. Joe for president!!
People wouldn't want Joe to be President, things would change, LOL Thanks for watching jumpingeneral!
@@LyonsArcade I need to come from Winston Salem and see you guys ! Have a great weekend 👋
@@jumpingeneral Come on down!
I remember playing this on the Atari 600xl, never knew Mario was such a gorilla hating jerk.lool
This is the only game he ever appeared in that he was the villian :)
@@LyonsArcade all is forgiving then, the 8bit Atari XL/XE versions of Mario Bros, Donkey Kong, Donkey Kong Jr and Defender where very close arcade ports for back in the 80s, Defender was probably my favourite back then.
p.s.
I love the content on this channel, very informative and in-depth, plus I can apply some of the tips to troubleshooting to some of my old 8bit computers.
Yeah, you really struck me with the comment about Haterz. I bet some of them would complain about you making a video while your voice is hoarse. But not me! I wouldn't even mention it! I hope you feel better quickly or already felt better quickly. Just get better dang it. Or got better.
Of course Mario bacame the villain. DK kidnapped Paula in the previous one, and you notice she's never been seen again.
You sure arent no billy mitchell, lunar lander hype!!
Didn't you hear, Billy is a cheater he can't play it was an illusion. I know that's true because I saw a neckbeard say it online
The ICONIC Nintendo arcade game.
I like it better than any of the Mario Bros OR the Donkey Kong Country series.
This is IT for me!
I wish more of the home ports had the cement mixer/conveyor belt level! Back in the early 1980s, the ONLY Donkey Kong port that had the conveyor level was the Atari 400/800 computer cartridge port. It was a reasonably accurate port that played like the arcade! Most of the other ports sucked and deleted the conveyor belt level! Colecovision was the only home console that had a decent DK port at that time.
The NES ports do NOT sound like the arcade although they're reasonably excellent ports. You CAN patch the conveyor belt level in the NES ROM of Donkey Kong. I did this years ago on a different PC and still have the ROM somewhere...
PS -- Notice I'm NOT making fun of Ron or Joe this video.
This is how much I LIKE Donkey Kong!
NO, the Fonz is not an electrician. You need an electrician or arcade repair man to get Kong throwing his barrels at Mario again--!
Well, maybe Mork from Ork could fix this game. I'm sure this technology is child's play for an advanced alien civilization that sends its scouts to other worlds in hard-boiled eggs!
This is a Donkey Kong Jr.
@@LyonsArcade 😅Yeah, I was aware of that 10 minutes after I posted that!
Should I delete the remark, or just own it?
Seems more cowardly to delete it now! 😆
Donkey Kong, Jr. is still good.
The original game is still the iconic Nintendo game. That's where Nintendo really started for people old enough to appreciate the history.
What's up with your logic probe? Looks like it's on life support :p
It works perfectly!
Speaking of China. Have they brought that dead balloon to you to fix?
All the info we have about the balloon came from the Gubment so I don't believe any of it... I wouldn't believe it even existed if my Brother Donnie hadn't filmed a video of it flying over his farm, lol
chip puller...humm I see a bent flat-blade screwdriver with a Dremel slot cut in it...
✋👏👏🙏🙏🙂
Another Donnie Kong game fixed people
Thanks for watching
Professor Ron you never run your mouth. Come on now Ron come on.
Oh you'd be surprised :) thanks for watching Dano
I played them games when they were new and I was never any good at Donkey Kong so I gave up on Donkey Kong
Yodelayheehoo
I now have an Amazon account..shame there is no New Zealand link..that withstanding, great video on this sunny Saturday afternoon
it has too much blue
Did you notice anything else you wanna complain about?
Not restored without cigarette burns. Inauthentic ;)
You coulda made people cringe even harder by piggybacking a known working RAM chip on top of the suspect one!
50% of what he say's is " I DON'T KNOW " but yet fixes the stuff..
i always liked frogger better............................................................just kiddin'
