This and Star Castle were two of the earliest games I played. My buddy and I would walk down the hill to the 7-11 with a dollar each and we would buy two candy bars and play two video games and still come home with a dime left over.
The inventory of the contents of Mr. Royce's mystery bag was a great change of pace...
I love seeing how huge those old boards are. Nobody would spend money to make a heavy duty game board like that anymore. That game ate a lot of my lawn mowing money.
It's a timeless game, I never played this when I was a kid but I had the Atari 2600 cartridge and would play it all the time...
This game taught me that I needed to stick with Pinball, video games were not my strong suit!
It's due to them being laid out by hand. Software PCB layout and autorouting would appear later on, but not common until well into the 80s. Some don't even trust them now.
@@6581punk known to cause cancer in the state of California!!!
Well, nowadays we wouldn't need to make a board that big for most anything. All that discrete logic would be handled by software nowadays.
I've set myself a challenge recently to design some electronics using only LS logic chips and it's really frustrating because I know I could make it in an hour using a microcontroller and a few lines of code.
I still have my Asteroids cartridge for my Atari 800xl from the 80s
It's a legend!
Thanks for the trip down memory road with this game. Pro tip: Focus on one large asteroid at a time. Hit it, destroy the pieces, then start on the next. Don't move much until later levels when the UFO shots get more accurate.
The Asteroids game was always one of my favourites back in the 80s! Thanks for repairing it.
That hungary fan company makes very good fans. The little dots are Kapton dots for a non-conductive surface, usually used for wrapping battery packs. I do enjoy seeing your repair videos.
Thank you viscountalpha, we appreciate you watching man like always!
"well not every vien, not right now !" LMFAO
I'm gonna get kicked off of here one of these days
@@LyonsArcade Remember, more than 4 hours see your doctor!
I fixed a nice old spaceduel cabinet years ago.. it needed caps and a +/- 27? Volt regulators in the Wells Garner monitor... worked great.. gave it to a friend. He ended up throwing it away when the power supply started making noise....
Don't worry, I got it out of the trash, saved it, and sold it for $1800 10 years ago!!!!
@@LyonsArcade it really was about 10 years ago.. did it have a home built regulator board for the deflection transistors power supply in the WG6100 display?...
Funny how hearing that sound takes you back in time. With all the different gaming systems and PC gaming nothing will ever beat the time my Grandmother gave me a roll of quarters when we went to the mall. The family went shopping, I went to the arcade.
Love those sound effects Ron..sound like Michael Winslow from Police Academy 😁
We try to be entertaining
@@LyonsArcade And you do a fantastic job
Yet one more amazing video Ron and Joe.
Really enjoyed watching you work through the problem. One of my favourite ever arcade machines! I look forward to your new vids, always hoping that you will be covering another 80’s video game. Thanks for this one and hopefully many more
We'll have another one next wednesday!
Thanks Ron! Great repair!
Joe probably had the problem diagnosed within seconds. "It's broke!" :-)
He's quick with it!
It is still onr of my favs. I like sound and gameplay a lot
It's a real classic!
Joe that is a thing of beauty I know you will do it justice and revive it
Let's Fix It!
@@LyonsArcade 👍🇬🇧☕️
So many awesome games in the shop!!
Another great video. I'm a pinball guy but watching you tackle a dead pac man board years ago is what drew me to the channel because video arcades are different, interesting and unknown to me. The sound of your logic probe drives my cat crazy lol
Tell your cat to DEAL WITH IT
Thanks for watching Ray!
Your use of logic would make Spock proud.
This game is one of the reasons I don't have much knowledge of the electronic pinball machines of the time. Asteroids was my "gateway drug" into video games.
You do a Great job explaining. This is all new to me. You are kinda like the Macgyver of arcade repair always having 100% success no matter the problem😎
I just don't upload the ones I can't fix!
@@LyonsArcade love the channel 👍
Thanks for sharing the troubleshooting technique friend!
Thank you for watching Terry!
Congratulations Ron on getting to 50K subscribers, well deserved.😀
Thank you Mr. K!
Deflection chatter is a great thing to hear on these. Generally it is the Verticle deflection as the horizontal tends to run at a much higher frequency that can't be heard, but it is such a satisfying sound when you are working on one of these. :)
Astroids is one of my favourite of the early Vector based games. Such a classic and so much fun.
It's a really unique sound kind of cool to hear it because you know that board is doing what it's supposed to. Little easter egg from the 70's and 80's!
This is why I have 4 asteroid deluxe boards LOL. Two work great. Two don't do what they should and although I appreciate the video. LOL. I have no idea. :) I got two great condition fold out schematics and original owners manual and the manual for the monitor. :) I have a dot that shows up when the brightness is to high or contrast!!! Also that original Asteroids shooting sound is just great. Asteroids Deluxe sounds different. I like the deluxe though but you have to go to great labor and expense to make sure your background mirrors / cardboard / and backlight are working like they should and it is just the Bomb!!!!!
Great vid. I've the same machine with the owl eyed coin mechs. Yup, burn in dot at the centre of the screen. Still plays great mind you :)
Great video! Hey for that old stuff a cheap analog 'scope is great! Thanks for reading.
Good morning Ron. I see were working on a good old button masher today. Man my buddies and I pumped a lot of quarters into them things back in the day.
Anything Atari is cool, I need to get some of their Pinball machines in, I've never worked on those and people are afraid to work on them, I AIN'T SCARED
@@LyonsArcade Don't be scared, it's only money. And time.
It's only money and time.
And frustration.
It's only money, time and frustration.
And the unending dread that the algorithm may change at any moment.
So it's only money, time...
😀
I'll come and visit you guys this fall. I'm about to move to Charlotte. 🇫🇮
Come on down, Jan!
Solid Oak Desk!!!! Pure Class.... heh heh heh! Nice.
I think it's from Italy!
@@LyonsArcade Besides your repairs, I do love your sense of humor Sir. Solid oak... Solid particle board, with a wood-looking sticker on top??? Kinda the same thing!
29:35 those are bridge clips for punch panels for phone use, you can put them across adjacent terminals. the usual way to use them is you run your line through the panel and then put those across to bridge them so you can take a line out of service for testing.
Came here to say the same thing. Those are bridge clips for a 66 block. It’s a very old way of cross connecting telephone cables. It can only be used up to CAT3 though, as it doesn’t preserve the twist (3-4 twists per *foot*). Now that we care about twists (CAT5e is 3-4 twists per inch), a 110 block is now more appropriate.
Thank you Kev and Joel!
11:03 -- It's got a heart beat. It's ALIVE!
Hey Ron, you are correct about the piezo buzzers. The Mallory Sonolert is one of the original brands that made them.
I never heard of Sonolert, I've heard of Mallory though
the LEDs the center pin is ground and the two outer pins each one if you put a small voltage to one of the other or both simultaniously you will get 1 color, 2nd color, or with both outer pins creates a 3rd color. and that long connector is a parallel port connector. same kind of connector the old school dot matrix printers would use and external floppy drives would sometimes use.
The dual color LEDs allow for color blending... very useful for things like state of charge on a battery circuit 😀
That makes sense thank you Ron!
They were really popular before RGB LED's came around, but there are still some uses were you may only want green or red :)
@@EsotericArctos I've got a single cell li-ion charger that blends from red to green as it works! Cheapest thing ever came with a $5 or $10 flashlight. Wire was messed up, I'mnsorry, it was broke, so I had to Lyons it up a bit. But in reality I "C'mon peopled" it up, a real quick and dirty hack "sodder" ( 😀 ) job that I am still embarrassed about and I know, in retrospect, that this is something that Ron would yell at me about.
I've sullied our name - I promise to do better, Ron!
Appears like the center leg is common and the sides are R and G anodes. You can get red, green, or combined yellow out of them, and if you dim one side more or less, you can get more tones. These can also make a really cool backlight for an LCD.
Hey Ron!!
Hey Jason!
would the d-4 (74s74) chip keep the monitor from getting high voltage? i recapped the deflection board and the high voltage (cage). still no chatter. maybe the diode? please advise. thank you.
"Serious" yeah right. I remember the first time I saw this game in the Phoenix airport. There were about 10 games with people lined up to play it.
The "some kinda connector" is a Centronix parallel printer port. They were big back in the 80s before USB stole it's thunder.
JOE CLASSIC, The counter LS393 output is 3Khz and 12Khz, but what is the 3Khz and 12Khz signals used for? What tests can you do to make sure the "spot killer circuit" is working? because all arcade monitors have a spot killer circuit but not sure how to test if its working correctly or not
21v dropped down to 15v is quite a drop and there's no heatsinks on those regulators either (or they're using the ground plane for heat dissipation). Those linear regulators convert the excess voltage to heat. Heat is the enemy to old chips like these.
That's what they tell you... but you're looking at a 43 year old board that the regulators still work just fine in. They're the original regulators too, with no heat sinks
@@LyonsArcade They seem to be far away enough from the other chips. You often see modern circuits where they've put heatsinks right by an electrolytic and they fail way too fast. There's enough air space in cabinet I guess. Old Sinclair (Timex in the US) computers would shut down when the regulators got too hot, people used to play them on the living room TV on the carpet so they would get too hot.
The PCB in that area also has tons of thermal mass with all of the ground plane there. So they have a heatsink, the PCB itself
I believe the current is not very high in those circuits, and the heat dissipation had been taken into account. If there is room, it does not hurt to put in heatsinks, but prepare to insulate them. IIRC at least in the 78/79XX series the heat plate of the neg reg is not a ground like in the positive one.
If I ever buy any 50 wide SCSI connectors I will use your Amazon link 🤣
you need a new and properly working probe. The one you got has given its best years of life. the pulsing on pin 40 was very confusing and would have mislead a lot of people if you didn't know the player lights on the control panel were not pulsing to a watchdog condition. you need to live have some luxury, working test reliable test gear
Guys on KLOV say to unplug the monitor when the spot killer is on, to avoid damage.
I've played Astroids a few times.I never realized you can move the ship. I thought the ship was stranded in a astroid field and you must survive. I have a handful of quarters off to find a Astroids machine to get my redemption.
Was this the first game with a microprocessor? I remember it was one of the first games where the bad guys would actually shoot directly at you I think defender was a similar thing.
I like the showing of the process of the repair proving it doesn’t take a genius with expensive test equipment to fix these problems. Great stuff keep them coming.
This wasn't the first but it was definitely early! The Midway 8080 boards came out well before this one. First processor game was probably mid 70's.... Thank you for watching Kevin!
Hey there. I have a board that runs really fast just like at 36:12 was there ever a followup to this video where you fixed the speedup issue, and if not, could you explain how it was done?
You have some sort of hack installed on your board, there were a bunch of ways to do it but they all involved the clock signals coming off the crystal, look and see if there are some wires that looked added soldered to one of the counter IC's in the schematics just past the crystal. It might say 32H 16H something like that on the schematic around the counters.
You always make the repairs look so easy. Stop it! You're making me look dumb. LOL!
It's easy, I just edit out all the tough parts!
@@LyonsArcade Hahaha...
Imagine the amount of soldering to find dry joints or broken traces to repair that :)
Which one of the asteroid games was the one that had the Thousand volt transistor on it or something some high voltage component that's real hard to get??
There is a diode in the high voltage unit that's hard to get. I think it's 20,000 volts or something.
Those metal clips you couldn't quite identify in Royce's bag looked like bridge clips for the old type 66 telephone punch down blocks.
Great video Ronnie. great chip knowledge. Are those new chips or old (new) stock chips? Thanks Ronnie for fixing a classic game I played a long time ago.
Those were New Old Stock, somebody mailed us a ton of them back in the day and we have been using them for years. You can buy them new though. Thanks for watching Frank!
What website can you look at schematics?
32:26 Thems fur plating PCB through-holes, as I recall.
fun and games
What are you using to replace the HV diode in high voltage module on the anode line? Those diodes are no longer available. I've tried to substitute with an NTE part that I was told would work but it didn't. What do you suggest? You helped me with an asteroids board last year and it's doing great.
We're using Varo H1809's and they're working just fine when we have to replace them. You can get them at www.ArcadeShop.com or on ebay....
@@LyonsArcade Thank you
It would be nice to see you soldering and replacing parts on the boards.
You think so?
@@LyonsArcadeYes sir! I really enjoy watching those kinda things 🤠
Are you in Charleston SC? I recognize the carpet from local arcade sales ads. Would love to stop by.
We're in Rock Hill, SC come on by next time you're in the area.
vector analog side is the +-15 volts vector digital is +5 you can bench test with 5 volts if its watchdogging to make it easier and only worry about the 15 volts when you need to produce an image
3 legged leds are dual color usually red and green
That makes sense Thank you Jan!
Hi there, i wish if you can do an episode about this pinball machine 1964 Ship-Mates, And thanks
in advance
Dang it. Seeing how that space invaders cab looks really gets me upset with what happened to the one I bought. Just seeing it's original glory paints a huge picture. I bought a cab that was painted all black, and half depth with a crime city board installed in it. Once I started stripping the paint though, I found out that they had completely butchered a space invaders cab. Now to at least bring it back to part of its former glory.
14:10 resistor R18 , tag says watchdog disable, can you lift one leg of that resistor to disable the watchdog circuit ?
There is actually a lug there where you can tie that to ground to disable watchdog, I've found in the past though that does.... absolutely nothing useful because the program isn't running properly in the first place (which is why it's watchdogging). In this instance it wouldn't have worked either, because the 7474 was incapable of putting out the proper signal and the 'watchdog disable' would still depend on that part of the circuit.
Thank you for watching Hill Billy!
It looks like the difficulty setting is on high on your game. :)
When you start moving out of the starting place instead of just sitting still and turning in circles you screw yourself that starting spot is a clear zone for a set amount of time that the asteroids pass by but wont hit you until they get further into there zig zag pattern as soon as you move out of that spot you get in the astroids path its like the glitch in PacMan you use the small dots to eat the big dots to clear the board and just keep going up the levels
My god I love it! Deluxe is a better game though. Space Dual is awesome too
Whatchu know about a little game called BLASTEROIDS????
@@LyonsArcade great game and deff the best control panel out if the series
I have an Asteroids machine now that powers on and everything but monitor doesn't work. My 2nd daughter is due in Jan so its being moved again for what will be her room. One day I hope to get it up and running, but for now itll sit in a back room for a while longer
We've done a bunch of videos on here about repairing the monitors, check them out when you get ready to fix it!
Jason kopp is making a new asteroids pcb for asteroids. It is called Masteroids.
That connector is a 50 wide SCSI connector.
believe those are 66block bridge clips
Joes Italian Arcade since 1976 "that's a spicy Pacman meatball"
that is an Amphenol Centronics connector likely from a parallel printer.
Oh No iTs rUnNiNg ToO fAsT!
(there's gotta be a speedup hack installed, that was a pretty popular mod)
I'm not sure, I couldn't see a hack but it did have the early set of roms in it, maybe they were faster? It could be one of the clock lines was messed up too...
@@LyonsArcade IIRC if you short NMI to ground, it also speeds up a bunch, so maybe whatever generates the NMI is stuck low. Or was it IRQ?
30:40 That looks like a SCSI connector.
No it's clean! :)
The one game I never see is an original Ripoff, is there one in there somewhere!?
Asteroids?
Sounds futuristic and painful
Yup, that's Asteroids.
Too risqué?
No that's something different
Oh man, great video but I'm even more confused trying to follow what each led, /beep means with your test pen and missing legend! Gotta write to Santa!
Looks like vga connector
So was it the 74LS74?
Yes
@@LyonsArcade Thanks Joe!
Hey theres still blood running through that it just ain't doing nothin right now lol
Yup, you wouldn't even know it without checkin; :)
i saw it at 38:09

Hello lil Everette 🇷🇺
Hello Lil Everette!
Asteroids people..it's broke but ain't for long
Opposite of playing the game where the aim is to break the asteroids :)
@@6581punk Yip
We're gonna fix it!
You didn't use hyperspace while playing, so no proof it's actually repaired. :D
Sounds like a tesla coil
its not an 'escape' button.. its a hyper jump button
You think so?
