Man, I love that game. I remember when it came out. I had a really nice Joust in my collection, and a Robotron. Awesome video, brought back lots of memories of fixing these machines.
The fact that you are diagnosing these issues live on camera, and showing the thought process is really amazing to me. I have pre diagnose the issue and pretend to troubleshoot every video I put out. Thank you for sharing your fantastic diagnostic work!!!
You know how it is, when you figure out the problem it's so fun, I try to share in the fun with the viewers if I can, it's hard to do though like you mentioned... thanks for watching Tecnolock, we appreciate it!
I believe it's because they're using 8 bits to represent the color space and subdividing it in to 3 bits, 3 bits and 2 bits, (3 + 3 + 2 == 8). This gives you 2^3 (8) values for green and red but only 4 for blue for a total of 256 colors. This ends up being acceptable because our eyes are far more sensitive to green and red than they are to blue light.
Somebody else mentioned that Trey, that makes perfect sense, thank you. I don't know enough about programming to understand how the bits are used so it didn't appear to me but I think you're right :)
Thanks! I love your videos. They're usually a nostalgia blast. Good work finding that pesky failed shift register. Watching you play Joust reminded me of playing Killer Queen in Chicago. Look it up.
@@LyonsArcade Only thing to know here is that bits are (unless you have really exotic hardware) always handled in groups of 8...the famous "byte". Just like the cents you put into those machines are put into groups of 25. Using 9 bits for color would be the same as having one game cost 26 cents. Possible, but what an effort!
You know the REALLY interesting thing? Joust shouldn't even have a cocktail mode! When you play with 2 players, you don't take turns-- you play at the same time, with the same screen orientation. The cocktail versions were table tops (instead of upright cabinets) with the players facing each other. The screen would change orientation based on whose turn it was. But in Joust, both players play at the same time! So that's an awesome troubleshooting trick... but why is it even there to begin with?? lol
You are the first person to notice that :) I thought about that shortly after I finished the video... as you may be aware the boardset for Joust is the same as some of the other Williams games, so all that circuitry on this particular title was completely redundant and unused.
Joe's Classic Video Games Back in the day, producing circuit boards were extremely expensive, so they designed motherboard/daughterboard combos. The motherboard handled the video output and the daughterboard the game logic. Instead of designing and manufacturing a monolithic board to handle everything, they made generic motherboards to handle the basics and made the daughterboards to handle the individual game specific logic. Daughterboards tended to be much smaller and thus less expensive even in lower volumes.
I believe that the reason that joust has a cocktail mode is that the monitor is oriented 180° to accommodate the position of the chassis vs. how the monitor is set up in an upright. it has nothing to do with the screen flipping 180° between player turns (as was already pointed out that both players play at the same time.
Something else that is cool for me is that unless someone else has done that same test before, that’s the first time the B chips have ever been used in the cabinet’s nearly 40 year history. They have just been sitting there idly waiting for their chance to do what they were made to do.
Joust is one of my top 10 favorite old school arcade games. Jousting with flying ostriches and dinosaurs and getting eggs. I wonder what the intial reaction was from the guy who brought this idea to his boss. I enjoy these fix it videos, I'm amazed by your technical talent and your ability to figure out schematics and such. Great and educational video and hopefully you'll do a similar fix it video with an original Punchout arcade game. Keep these awesome videos coming!
We may do a punchout in the future, I have a gameboard here and a cabinet I just need to put it all together. The gameboard already works though, but maybe it'll break, LOL
@@LyonsArcade I just hope that maybe becomes a yes. Of course you all have to put "top priorities" for your business on the frontburner. It's all good regardless. I also like this channel because your sense of humor and personality is conveyed during the videos.
One of the things that impressed me the most, from mid 1982, going well into 1983, was the incredible jump up into the chip and coding technology of these arcade games. Especially how incredibly well they put out the high quality sound and full color graphic screen; even colored text! I never really saw a computer display that before then. I always wanted to see the huge logic board of these games, and wonder what each chip did. It was like living Tron in real life!
I was very small then so I didn't experience it but yeah a lot of folks playing modern games don't know about a time when the arcade games were so much more advanced than the home systems. They could do incredible things and the only way to play them was in the arcades!
@@LyonsArcade, exactly! I was 11, 12, 13 from 1982-84. All I knew back then was the Atari 2600 and the Apple 2E at school. When I did make it to the huge arcade places, I was blown away each time with the advancements in the logic board chips and coding. Getting the very most that you could, from such little RAM and Video space. I usually stuck with the Pac Man, Mrs. Pac Man, Donkey Kong, Pole Position games other similar games. Even better was the New Wave Music that went with the Arcade games back then.
@@xyrzmxyzptlk1186 Yes you're on the right track, I was curious to know if it had the same meaning in the U.S. as the U.K. Sounds like some kind of old school vajazzle shop.
@@LyonsArcade You know, on board AA Batteries were not the brightest idea. I mean, a little foreknowledge of the fact that they leak and cause all kind of corrosion issues. And then the Battery Clip that Williams used would not hold up to that corrosion and fall apart. FYI, I have been in the Gig since 1989. Lots of fun. SALUTES
For giggles you can get a cheap infer red thermometer from harbor freight for example to scan component a if your looking for hot spots on electrical parts , just a suggestion.
It was common practice for service techs that are called out to fix a problem and then quote more than the customer is willing to pay to rotate the yoke 180 deg. When the customer refuses.
@@LyonsArcade yeah, some folks realized that to troubleshoot the problem the tech actually had to fix it and started telling their pals and all of a sudden tech weren't getting paid and were out the cost of the parts used. Slimeball customers.
Some particularly fancy troubleshooting here... Does this mean that the other four shift registers are normally completely unused on the upright? Could they be spares? Not that those chips are particularly rare, I suppose...
Yes, that's correct, you could take all 4 of them off the board with no issues on the upright. They're inexpensive and they make them new, but you may end up in a situation where you don't have one available and have this fault, so you could rob one from the other side and get it back up and going again!
@@dangermartin69 You know, that's a good point. I looked it up and there were Joust cocktail units--but to support the coop gameplay, they had both of the player controls on one side of the table! So there would be no need to invert the display at all, and those chips have absolutely no regular function on a Joust.
Went into cocktail mode. Looks like you put it into cocktail mode. I was bored once and played pterry challenge mode. I waited until pterry came and went pterry hunting
First of all, thank you for sharing your work; I’m sure it’s difficult through a camera. If your interested, I have an asteroids main pcb that has doing me in; would you be up to doing a troubleshoot video on it? Of course T&M would be covered. Thoughts? Thanks again!!
Hi David! Thank you for watching, we appreciate it... unfortunately at the moment we have so much back log that we can't take on any more repairs... what is yours doing?
Joe's Classic Video Games when I first got it , the initial screen came up but would reset as soon as the asteroids began to render in attract mode. I checked all voltages and they were good on the main board. I inspected the board for bad solder and loose parts, broken pins and such (looked good) and cleaned a couple of the chips that seemed to have crud between the pins. After that I tried to run again, and now I get the spot killer light and the player 1 and 2 buttons light up continuously.(no blinking) and no game sounds. And no response in test mode. I am thinking the vector chip is possible, but that is programmed (I believe) but I don’t know the process of reprogramming, so I am reluctant to pull that in fear of damaging it if it isn’t the root cause. Feels like I’m going backwards on this animal. Thank you for listening, and offering guidance as you have time. Email me if it’s easier at Path2ground @gmail.com thanks again!!!
I had an old tube tv that got tipped on its front and it did the same thing the screen is shot because little components got shifted I’m not sure if it can be fixed
Elizabeth, is it all different colors? If it is, you can fix it with an electric motor, something like a drill or even a powerful hair dryer, get it near it and the motor will realign the colors on the screen. Or you can buy a degaussing coil if you want to do several and have the tool....
The reason it has 3 red, 3 green, and 2 blue is because it operates on an 8 bit chip. Blue is the coolest of colors, so it uses black (or the absence of color) as the third "blue".
It doesn't unfortunately. The thing is too, cocktail mode only flips the screen upside down while the second player is active, so if you DID switch it into cocktail mode, you'd have to play a game and see how it looks while the second player is up.
3 bits of red 3 bits of green and 2 bits for blue. 3 + 3 + 2 = 8, so 8 bits per byte... They wanted it to fit into 8 bits, probably to fit it into some 8 bit ROM. ;)
@@LyonsArcade see, I've thrown my back out and was stuck sitting on the throne with nothing else to do and now I think I have made this comment before... Maybe even on this video... I think I need to just put the phone down and take a nap before I break a thumb. ;.P
I'll bet there's different ones that are made better, but that one was 40 years old they just fail eventually... if it fails again, it's in a socket now, makes you wonder about the other ones though, huh?
@@LyonsArcade long shot, but how about, the monitor deflection yoke connector has X and Y flipped backwards (or plugged into the alternate connector) and that monitor came out of a mirrored shooter game? I don’t think joust has a screen flip switch like pac man.
A friend gave me this game for free just because the screen went out three years later I threw it in the front of my yard 😑😫one of my family members decided to break it into a hundred pieces since it was trash 😠
LOL That would have worked just fine. You can actually invert the yoke wires on the monitor too, which would have made it display upside down.... which would have been right side up :)
Joe's Classic Video Games : I did not. However my Joust still has an ashtray screwed onto it from back when it was in the arcade in 83 to 86. Can’t have those hot tips ruining the game controls!
@@forevercomputing Have you ever seen a cocktail arcade table? They didn't use mirrors in Cocktail mode. The screen just flipped for the player on either side of the table.
@@robertatkinson6864 There were some cabinets that used a reflector for the screen, and had the display inside facing upwards. Maybe a different thing, but I've seen those before too.
Bummer they replaced the original Power Supply. Nice job working logically through the schematics. Wow man, interesting technique overlapping the chip, love it. Good stuff, be well. -Mitch
I agree, the crazy thing is we fixed the original power supply last time (it must have failed again, or at least they thought it did). Those Williams Power supplies are very reliable in my opinion. Thanks for watching Mitch, we'll see you next time!
Why only 3 red 3 green 2 blue.. Simple 8bits per byte so with only 8 bits if 3 bits per colour 9 bits total hence we have to drop some colours and blue gets short changed
*there was this restaurant that had a original midway ms pac-man arcade cabnet and the screen would be normal on the insert coin screen but when you start a game it plays upside down*
@@LyonsArcade in the 1980s i played it so much i had ships lined up all the way across the screen .my high score i estemated to be around 34 million but every time i got to 1 million the score would go back to zero .defender 2 was even better you could warp .i remember playing over 8 hours or more off one quater. my friend would take over if i needed a rest and a bathroom break.it wore me out but it was so much fun to play back then i loved this game
Why only 2 blue resistors? Human eyes aren't as sensitive to blue light. You only have 8 bits to split between 3 colors, so blue gets the short end. Thats my answer.
They made a "19 in 1" board awhile back that had it on it... it was a little chinese board but played all the Williams games pretty good. Thank you for watching Bill!
Im currently restoring an old pole position 1 and 2 arcade cabinet i ordered parts to repair the power supply units as they are both fried is there a conversion to a newer hap power supply ?
They don't make a new power supply for it because it had an amp on the original Atari power supply. The originals are pretty reliable though once they're repaired.
Ahh one of my favorite games. So awesome you figured out what the problem was. Watching these videos is always interesting to me. Granted I never repaired a arcade cabinet, just it's fun to see how all of the games work.
Glad to see people are still fixing old arcade games there was a shop by me but of course they closed it kills me when people say plugged up instead of plugged in a toilet gets plugged up anyways thumbs up for the video
I fix pc and laptop mobos. I'm so glad I wasn't doing that back when these games were out. The people that designed those games were geniuses. Not to take away from them fitting these games on a few thousand lines of code now. Had I been into fixing those games back then I would be a billionaire today. I'm loving your videos as I'm able to look back at the past in a different perspective. Subbed
Ron the more I watch your videos the more I doubt that there are people "much much much" more talented than you. We all stand on the backs of the giants, and you sir are growing up. Well done.
Your sync wire isn't making good contact with the gameboard, put the old one back in and see if it's still synced, if the new one isn't, then it may be the game is set in 'vga' mode instead of 'cga' mode, look in the book. If you have an older monitor like this it's CGA if you have a computer monitor it's VGA.
@@LyonsArcade you know the blue part that has 1 or 2? The switch goes up and down. I had "2" up and moved the switch down. Now it works, but I realized the 15 in 1 jamma is horizontal. So, I would need to turn my head or the monitor! Lol

@@LyonsArcade Thats what I thought you were going to do.
thy game is over
Thou Art Dead!
**Turn screen downside up** Profit.
SHALL WE PLAY A GAME HOW ABOUT A GAME OF CHESS
やりましたね、ゲームプレイして見たいですよ(≧▽≦)
ぜひ遊びにいらしてください！
Its not upside down.
Thats 2snor!
It didn't sell very well cause it was really boring.
I just woke up!

You sound just like it :)
Needs cleand
Meh, just turn the monitor over. 😉
It would have worked :)
One time I opened up my Joust and found 3 cigarette butts inside the cabinet from 1983.
Did you save them? :)
Joe's Classic Video Games : I did not. However my Joust still has an ashtray screwed onto it from back when it was in the arcade in 83 to 86. Can’t have those hot tips ruining the game controls!
I misdiagnosed the problem... I thought the cabinet was upside down.
That would have been too easy :)
I figured it was the Australian version...
I would have just left it in cocktail mode and physically flipped the screen over.
It might have been mirrored as well. I believe in the days, a mirror was used and you were looking at that.
@@forevercomputing Have you ever seen a cocktail arcade table? They didn't use mirrors in Cocktail mode. The screen just flipped for the player on either side of the table.
Big brain gamer move!
@@robertatkinson6864 There were some cabinets that used a reflector for the screen, and had the display inside facing upwards. Maybe a different thing, but I've seen those before too.
Bummer they replaced the original Power Supply. Nice job working logically through the schematics. Wow man, interesting technique overlapping the chip, love it. Good stuff, be well.
-Mitch
I agree, the crazy thing is we fixed the original power supply last time (it must have failed again, or at least they thought it did). Those Williams Power supplies are very reliable in my opinion. Thanks for watching Mitch, we'll see you next time!
“You shall prove your worth by facing me in a joust!”
Why only 3 red 3 green 2 blue.. Simple 8bits per byte so with only 8 bits if 3 bits per colour 9 bits total hence we have to drop some colours and blue gets short changed
I must have dropped $500 on joust gaming as a kid.
Super fun game, such a great design!
*there was this restaurant that had a original midway ms pac-man arcade cabnet and the screen would be normal on the insert coin screen but when you start a game it plays upside down*
I noticed when you had it in cocktail mode the demo ostrich disappears about halfway up the screen. At about 12:22. Nice fix!
Whoa! I didn't notice that. Wonder if it still has that fault?
Nice slam dunk on the troubleshooting...Cheers Jeff
Thank you Jeff, this one made a nice clear cut video I was happy with that :)
i played that same game in the arcades in the 1980s and defender 1 and 2 it was fun the old games are the best it takes skill to beat them.
Definitely! I've seen some folks play Defender that really knew what they were doing... incredibly tough game.
@@LyonsArcade in the 1980s i played it so much i had ships lined up all the way across the screen .my high score i estemated to be around 34 million but every time i got to 1 million the score would go back to zero .defender 2 was even better you could warp .i remember playing over 8 hours or more off one quater. my friend would take over if i needed a rest and a bathroom break.it wore me out but it was so much fun to play back then i loved this game
This was my absolute favorite arcade game. If I was going to buy an arcade game... This would be the one!
Yeah it's very well made in my opinion. Everything from the visuals to the idea to the sounds....
Why only 2 blue resistors? Human eyes aren't as sensitive to blue light. You only have 8 bits to split between 3 colors, so blue gets the short end. Thats my answer.
You're probably right! That makes a lot of sense.
That’s how video compression works, too. It often has less bandwidth for blue, especially on older formats.
Keep the Videos coming, the Member Berries are potent.
Another new one tomorrow :)
I have been trying to find a multicade that has this game. So far no luck. I’ve always liked this one.
They made a "19 in 1" board awhile back that had it on it... it was a little chinese board but played all the Williams games pretty good. Thank you for watching Bill!
Please please! post back here if you find it. I like the Jamma builds but the games aren't often well curated.
just switch out the anti matter inducer......
I looked at it first!
Your videos are like an arcade school!!! Super educational & I really enjoy watching them :)
Thanks Chinasaur, we appreciate you watching :)
I can't stop watching these repair videos!!
Glad you enjoy them!
*Why Is the Screen Upside Down?????* -- Clearly, it is in Australia mode. (yeah, yeah "low hanging fruit", don't care.)
Any good joke is worth repeating often :)
They use the mini arcade at Walmart my mom would not let get it so it sit there until it got removed form shelf
They didn't let you get one Erica? You might be able to find a used one somewhere though!
Funny that back then 100 chips where used .... today maybe 2 chips used today in place of 100 from back then
Time marches on :)
Im currently restoring an old pole position 1 and 2 arcade cabinet i ordered parts to repair the power supply units as they are both fried is there a conversion to a newer hap power supply ?
They don't make a new power supply for it because it had an amp on the original Atari power supply. The originals are pretty reliable though once they're repaired.
Is this the same one that had the bad PIA chip that wouldn't allow you to input your initials when you got a high score?
The exact same one :)
Ahh one of my favorite games. So awesome you figured out what the problem was. Watching these videos is always interesting to me. Granted I never repaired a arcade cabinet, just it's fun to see how all of the games work.
Thank you for watching, we appreciate it!
Glad to see people are still fixing old arcade games there was a shop by me but of course they closed it kills me when people say plugged up instead of plugged in a toilet gets plugged up anyways thumbs up for the video
Toilets plug down power plugs up to the pole above the building :)
Joe's Classic Video Games never heard anyone say my 🚽 is plugged down lol do you say cut it on or turn it on
I fix pc and laptop mobos. I'm so glad I wasn't doing that back when these games were out. The people that designed those games were geniuses. Not to take away from them fitting these games on a few thousand lines of code now.
Had I been into fixing those games back then I would be a billionaire today. I'm loving your videos as I'm able to look back at the past in a different perspective. Subbed
Thanks Joseph, we appreciate you coming along for the ride! See you on the next video man!
It should be noted that Joust was the inspiration behind Balloon Fight.
Both cool games :)
RIP Mr Iwata
Ron the more I watch your videos the more I doubt that there are people "much much much" more talented than you. We all stand on the backs of the giants, and you sir are growing up. Well done.
There's plenty of people better at it than me, just read the comments :)
its funny how someone so very very smart can like playing video games
Nothing wrong with playing video games :)
It’s so good to see these classic games/machine still working ...Cheers!
Thanks for watching Chris, we're saving all of them 1 at a time :)
I enjoyed watching you play just Ron pure arcade goodness
Thanks David we appreciate you hanging out with us!
Beautiful diagnostic technique! Efficient and elegant!
Thank you for the nice comments Doug, I appreciate that!
Bring the machine to Australia, problem solved.
I would but I'm afraid of Kanagroos!
I have installed a 19 game jamma board, but the screen goes sideways and keeps scrolling from right to left without stopping. Please help!
Your sync wire isn't making good contact with the gameboard, put the old one back in and see if it's still synced, if the new one isn't, then it may be the game is set in 'vga' mode instead of 'cga' mode, look in the book. If you have an older monitor like this it's CGA if you have a computer monitor it's VGA.
@@LyonsArcade you know the blue part that has 1 or 2? The switch goes up and down. I had "2" up and moved the switch down. Now it works, but I realized the 15 in 1 jamma is horizontal. So, I would need to turn my head or the monitor! Lol
a popular arcade for a while in early 80s was PopEye.
Yes that was a great game Chris! We've got a video of one here on our channel somewhere...
Spent many a quarter on joust, Popeyes, and robotron. All awesome games.
