I'm a arcade collector and enjoy your channel content! I learn a lot from your videos. I even watch brother Donny channel you advertise. Thank you for your time!
Great video! I my younger years I always wanted to learn assembly language but often would get intimadated. Now that I tinker with electronics and have a better understanding of logic circuits I am thinking of giving it another shot to see if this old dog can learn some old tricks :)
Great work Ronnie and Joe. ….These seem a lot harder to understand than an EM pinball. …I enjoy watching you sort these issues out, …but I’m glad the world isn’t waiting for me to do it,…as it’s gonna be a long wait! Thanks for posting this great old arcade classic.
So satisfying to see it get fully repaired. Kinda amazing anything worked with so many bits wrong. Using the oscilloscope to check the vector output is a great little trick. Thanks again for sharing these videos with us.
Another great fix! 👍 It’s good how well documented these early games are and that replacement chips seem to be readily available, so it’s possible to diagnose issues by tracing the schematics. So many later arcade games use custom chips so when they die there’s no replacement parts available.
when fixing audio amps in general, if i have crackling that can't be tied to dodgy pots, i always look towards the active chips. either preamps if they exist, or the main audio transistors/ics. i've only had like, one case where it was something else causing noise in the circuit (a slowly failing resistor in the chain), but its usually the chip(s) failing.
Super cool Ron ! Thanks for taking through the whole process. You and Joe make a great team . Always enjoy every video , even though I’m a pinball guy . Just enjoy your content. Hope you and your family had a great Thanksgiving!
Ron, the victor of vector game repair! (Roger, Oveur, huh?) 😃 Love Asteroids! Great to see you logically track stuff down and get it working 100% 🤠 And bless the folks at Atari for making excellent documentation - something sadly missing in modern stuff where repair is treated like a dirty word by many companies.
Really cool watching you work through the problem. I still love watching the quick fix arcade stuff you do it is cool to see something beyond a bunch of caps and a power supply! Hope you got to enjoy some family time on Thanksgiving! Off to tour a mobile home I believe...
did all my black friday shopping through your guys' amazon link. hope it all went through. got a vaccuum cleaner and a bunch of echo show's. thanks for the video.
I've been in electronics for 37+ years, and still picking up tips from you two. Love the piggy backed IC trick - though what's the likelyhood of blowing the new chip that way?
Wow great job guys! I was sure when Ron was looking at the circuit that it was going to be a bad EPROM as I can't imagine the CPU would know if any of them had lost their minds because if the CPU knew everything, it wouldn't need those EPROMs. I do think LED's would really make that game pop!
There is a circuit designed into the software, where it can tell if the eproms are bad or not believe it or not. It's encoded in the very beginning of the software, so when it turns on it checks the roms and tries to read a checksum off of them, which is created by all of the info on the rom. If it gets the wrong number back, it immediately stops and says hey that rom is bad. If your program is trying to run (like this one was) usually it's not the roms...
Hook up an analog scope and you can really see it! Looks like some bondo will be needed next. Ive fixed a couple of these boards and got an asteroids cocktail a few years ago for $300.00 o then found a NOS glass table top on eBay for $300, bought it and sold my scratched up one for $300 so ended up getting the new one for free 😁
Great diagnostics and repair work guys!

I love when you do these videos, they are a goldmine of useful information. Thank you!
Nice work Ron.
I am just pleased you used a scope even if it wasnt the way it was intended to be used 😂

Gotta own an Asteroids in a collection! Great repair of a legendary game😎
Hi Ron. Thanks to you and Joe for the video. Catch you Tuesday. Have a good weekend!
Another one for the WIN column! Another level up on your skills! Fantastic!

Very excellent video Ron , You and Joe keep them coming, Hope you and Joe had a wonderful thanksgiving with your family

Seeing the copyright year of '79 on the Regulator/Audio board really makes me feel old. Yeah, Asteroids is 4 years younger than I am.
Happy thanksgiving Ron and Joe you guys rock keep those videos coming

Hey Ron!!
You guys are awesome! And using a scope that way was genius!
did all my black friday shopping through your guys' amazon link. hope it all went through. got a vaccuum cleaner and a bunch of echo show's. thanks for the video.
I do see it on there, thank you!!!
Great job boys! Regards
Merry Christmas!!!! Tis the season

@@LyonsArcade Wow thank you! Hard to imagine a game this old did all of that!
Those Tech Forums are awesome... someone out the on the interweb knows the answer. But also alot dont LOL
Great vid.
Nice job on the repair I think that chip must had shorted
Spot killer bubba! 😊
You unbroke it. Good job

SPOT KILLER! I was yelling at my laptop, lol
👍👍👍😎☕
The next time I have an Asssssste..roids problem I'ma call Dr Joe & Dr Ron!
