- Who doesn't love a good C64 repair session? These machines are both easy to fix and also can be tricky sometimes. So let's break out the schematics and oscilloscope and fix a couple of these machines!

You can never get enough of C64 repairs.
One more like to 64
Not sure how many comments you get against C64 fixes but it has to be a minority. Regardless, I still feel you started this channel sharing things you like. That is what got you to where you are today. Don't try and follow what you think people want because that would be such a moving target. Remember where you began and we will be there to watch.
Channels need to grow and change. Stay stagnant and the channel wont grow. There is no right answer. Even channels that have been inactive for years have hundreds of thousands of subscribers. Also there are great channels with 4000 subscribers. Seeing as he makes 3 times more content now then you can pick and choose to not watch these, you dont need to watch every video from a content creator.
I totally agree with you, but this is now Adrian's primary source of income, so he may want to taylor his channel to the masses. I'll be watching either way.
Tailor
;)
@@Lbf5677 I've been called many things, but a good speller has never and will never be one of them. My sister got the good spelling genes.
@@someguy2741what is everyone’s obsession with growth, from Wall St on down all we hear about is growth. Why is being happy at some level not ok anymore.
“Don’t worry, this is not gonna be a repairathon” - me: awh ;(
I know right!?!?
Right! Why it would be something I "worry"... I love them!
hahaha same here!, we want more C64's yeah!
sameeeee
I was hella saddened by the no repairathon 😢
Never stop making the repair videos. I'll never get tired of watching them.
I'll never get tired of seeing the useless RF shields going into the trash. :)
@@LeftoverBeefcake they were put there to satisfy the FCC?
@@garthoswald1621 Originally yes, but these days they are useless for that, and even for use as heat sinks. My friend MindFlareRetro did a video here on CZcams investigating how good the shields are at pulling heat off the chips. You're better off putting a sink right on the chips themselves. In some 64C's the shield helps hold the keyboard in place, so that's the only time you really can't ditch it unless you have, say, a 3D printed alternative.
We were really missing the 8-Bit Dance Party already. 😄
👋
time for the 16 bit dance.🤣
Personally I love the C64 repair videos even if I will probably never repair one. I find them rather entertaining and interesting.
I'm high all the time🤣🤣🤣
Back in the 80s, none of us would've really known the SID was bad. It was just the way it sounded, and if we went to anyone else's house and heard something different we would have thought something was wrong with their computer LOL! Thanks Adrian! And...MOAR 64s!!! :)
imagine having to solve these problems with you modern computer🤣🤣🤣
@@SaraMorgan-ym6ue Today's computers are more reliable (mainly due to "switching" power supplies, as opposed to the Commodore "Brick" supply) and super cheap. My Dell 7010 w/ i7 CPU was just $23, so I bought 3 of them lol. So essentially, $23 solves your modern computer problems for a duration of 10+ years lol. Still, the 64 is the computer I never had but wish I had, so I got a vic20 and 64 on ebay a few years ago. It's reassuring they can be fixed easily. And now with GPT4, you can have it write simple programs for you for it, adding a new dimension of fun and retro fun =)
Two more C64's rescued from being scrapped. At 4:54 I immediately l noticed that pin 8 of the 6510 looked super corroded.
Funny, at the same time stamp, I spotted C20 at the bottom left (looks like a resistor to me though...) that is completely bent down. Maybe touching R28.
they will be scrapped soon
Me too, i though he'd address this later in video, but it didn't happen and i even forgot about it while watching
C64 repairathon >> insta like
Another one of these series is always welcome...
It's a good thing that they sold so many C64s. There will always an infinite supply of broken computers to fix. I bought two recently and sadly, they both worked.
I betcha they sold almost as many as the blank Maxell cassettes people used to buy to record mixtapes on.
@@rommix0 I'm still waiting for somebody to do a repair video on a Digi-Comp 1.
200 years from now they will at the efforts of our generations. Everything from the 90s on will have been destroyed, but all of those Commodores have been carefully repaired, preserved, and all software has been carefully archived.
@@danielmantione Unfortunately there won't be any original C64s left even 100 years from now on. Even today the chips from the 70s and 80s are dying left and right, and plastics are getting brittle and returning to their original state: oil. It's just how it goes eventually, no matter how nicely you store these things.
Even vacuum bulbs including CRT's are starting to fail that were manufactured in the 30s through the 60s. It's not about quality, but the time takes it's toll, nothing's forever. That's why we need to cherish and love these things while they're still around and kicking.
However, the software will be mostly archived and the hardware is so well documented, that it's no problem to replicate a 100% compatible replacement chips, if there's desire to do so. And who knows what kind of tech we (or not we, but them) have then.
Only the analog stuff like SIDs will be harder to reporoduce, since they're not exactly precise devices, but each and every one have a slightly different character. And it depends on the listener's preference is it a good replica or not by then. Sure there won't be any og SID listeners left to complain about it.
😂
Yay! C64's back to your roots so my wife and I can play "Is the SID broken" game.
As someone with minimal repair and electronics experience, who now owns about a dozen breadbins of unknown operability, these videos are invaluable :)
Woot! C64 repairs! Thanks Adrian!
C64 repairs are awesome! Love it. Don't know if anyone else does this, but I like to try to predict what has failed.
It's funny that even though I'm not a 64 guy, I can immediately recognize a "wrong" dance-party.
C64 repair videos are always welcome!
10:07 "Dead Deco Bef Cord" An intriguing message from the injured C64!
Yes to more C64 repairs! To me, things like this are the main appeal of the channel. The old Macs, Amigas, all of the 16- and 8-bit machines are the focus for me.
Back to the CLASSICS! Love it!
I found you from your C64 repair a thons and will always click them immediately
The feeling of turning a corner, and seeing an old lover, has nothing over the feeling of hearing 8 bit dance party again.
Yes, more Commodore 64 repairs!!! Personally, i would have removed that warranty sticker and kept it as a piece of history since seeing intact onesvis rare. Loved the video and looking forward to when you repair the other C64s.
Many C64s were incinerated in landfills. A few went to Adrian's C64 heaven.
Yeah!!! This is pure gold! I like the c64 repairs because I can say oh that’s a memory chip and then you say it! ❤
Awesomeness.
Yes, please more c64 repair videos! I learn so much with each repair.
Back in my days repairing arcade games, I couldn't do without my can of cold spray.
In this case, as soon as the PLA warmed up, it stopped working. That's the reason we all used CO2 sprays when troubleshooting stuff that worked when cold.
I have no idea why but your C64 repair videos are my favourite videos of yours. Please keep them coming.
My retro collection leans toward Apple and Atari. I was never a Commodore guy back in the day. That being said, I really enjoy these C64 repair videos. I feel like I learn a lot watching you go through the troubleshooting process. Thanks Adrian!
Sadly Adrian won't be repairing many Atari 8-bit machines because they (mostly) just keep working!
@@rabidbigdog unless it's the later Jack Tramiel Ataris...
@@waltciii3 True.
I've never own a C64 and I'm sux at soldering electronics but I love these kind of video for the investigation and the logical thinking.
It never gets boring.
C64 black screen fix is your core business, continue repair is really nice!!!!
Six years ago I got a C64 which is pretty rare in my location. And it's still waiting it's time) I guess I finally need to fix it)
Yes, I still need to make a test power supply for one I bought a year ago. The estate sale had two breadbins, but only one power supply (which they were charging separately for). I already knew not to trust that one (I did point out to the people running the sale that it was a bad power supply). They also had a couple C64-C's in their boxes, but I didn't have enough cash on me (didn't expect to go to a sale, and it was off on some back roads). Unfortunately couldn't make it back to the sale later.
The ROM and PROM were the most common repairs I did at the repair store I worked at years ago. Commodore had a great tester for them. My work partner and I also did some modifications to the prom so that you had a shortcut to startup. Our favorite was the load command we assigned to the f1 key *.* was fun playing around with them. We also could use the PET computer to copy just about ANY protected floppy. we also were able to make game cartridges used in ATARI or other machines we would copy and use on the 64. those were fun days.
Please never stop with c64 repairs! They are interesting every time. I should also note that your tips helped me identity and resolve bad RAM on mine 😀. Thanks as always, Adrian!
Yes more C64s please.
Yes, back to my favorite black screens !
Yes, more C64 videos!
Always up for a good C64 repair vid.
First thing to remember about C64 repairs, use chip sockets because they will break again. Bad RAM chips are easily detected with your finger, because they get hot or by cutting the b+ pin with snips.
My old man chucked mine about 15 years ago. I had probably 300 games. Good job I love him or I honestly think he wouldn't be here anymore.
Superb video. TBH I’d watch people like Adrian just chat about anything or repair anything. Why? It’s a bit like the UK Top Gear Trio Jeremy, James and Richard, you just love watching and following good people who bring good things into your life. I love this channel for the multitude of things Adrian fixes, chats about and teaches.. I’ve learned so much from watching your videos and love your methods. Some people have IT and others don’t. Adrian is one of those that does.
This is very cool... I still have my C64, 1541 II floppy drive & 1802 monitor that I purchased while stationed in Germany in the mid-late 80's and it still works great...
You are holding my childhood I had one and programmed it when I was a kid in the 80's, LOVED it
Still can’t get used to the fact that so many people on youtube NEVER uses an oscilloscope. For me that is the first tool that you grab, even with power supplies. 👍👍
Super useful, I’ve got a C64 with the same symptoms as that first one (no video on start) and indeed it has some of those MOS logic chips including that same one on U14. Will have to look at those when I try to fix it!
Love the C64 repair videos. Could watch forever!
Always a pleasure to see you fix C64's. Please do more videos like this!
Definitely enjoy the c64 repair videos. Just learned about the MOS origins earlier today. Very cool to see you talking about the MOS chips in this video.
I love this, I'd watch you do C64 repairs like this all day and night, maybe throw in a 1541 here and there.
We want more C64 repairs they never enough
I love these videos. Thank you for making them
I love your energy and enthusiasm!
I LOVE the 64 videos. I've never played with one myself, but I enjoy the videos. I was a TRS-80 model IV and IVp guy...
Great video with lots of useful information! Thanks Adrian!
I love the C64 repair videos! Keep em” coming!
Thanks Adrian, such a great video. I love your repair videos.
GREAT VIDEO!!! Love watching the repairs!
That was really quite a useful video. Thank you!
Thoroughly enjoyed thanks Adrian 🍻
Love the 64 repair videos, that’s what got you on my radar in the first place ❤
Would love to see more. Great video as always.
Never owned one of these, but my friend that lived around the corner from me did. Such great memories. KANE, Kickstart2 and Agent X 2 to name a few.
Miss those days.
I love these repair videos - it’s what brought me here in the first place!
Hi Adrian thank you for posting , love the trouble shooting and fixing Videos of the Commodore Machines , great learning experience.
Don't recall which came out first but I had a C16 back in the mid 80s and there was a game on it called Fire Ant. Absolutely loved it.
Adrian really needs an 'it freaking works!' shirt. I'd buy it!
Yeeeehaaaa... A C64 repair video.. Love them. Thanks Adrian ❤❤❤
I always enjoy your C-64 repair videos. I always learn something.
Love the oscilloscope troubleshooting work. It helps a lot.
Another brilliant video. Thank you.
never boring, love c64 repairs videos
Nice work and very informative
Please PLEASE keep those C64 repairs coming! I simply cannot get enough. I keep learning all the time. It is extremely useful IMO. Thank you so much!
Love the C64 repairathons. I’ve learnt so many transferable troubleshooting techniques, and a revived passion for the C64. Thank you Adrian.
No matter how many C64 repair vids you do, I still love seeing the process. If anything I enjoy it more because your videos have made me more familiar with them. Keep them coming!
Hi, Adrian loved the video. Keep up the great job your doing. Stay safe to you and your loved ones.
Big thumbs up for C64 repairs! The more videos there are of it, the more information there is to help me and anyone else who is working on a dead C64. Some faults are rare or obscure so the more resources the better.
love these 64 repairs so much
I love your troubleshooting videos! and even more if they are commodore!!! looking forward for the next ones!!!!!!!!, thank you!.
Keep them coming!!
C64 repairvideos are the best :) Keep em coming!
Back in 1984 I was a repair technician on these at the Commodore manufacturing plant in Corby. 40 years, my how it flies by.
I still have a working C64 in my loft, I must dig it out at some point.
What I loved about the Apple II and IBM PC, was they didn't use any ASIC ICs on the MB.
Those two computers were, and still are a great study on how microcomputers and logic circuits work.
When computers started using ASICs, I went the MCU software way and gave up hardware repair, since I knew how disposable everything would become.
Started with the famous 68HC11. Today, I develop products around the ESP32. I made the right choice for once!
Love this. Great tutorials on troubleshooting regardless of what is being worked on. Also takes me back to when i was an electronics tech in the 80's. My time!
This was a really interesting video, I love watching you go through the diagnostic process and ultimately honing in on the trouble area. I would love to see a follow-up video where you look at the other C64s and try to repair them.
born and riased in SE portland.. often wonder if my old C= computers have ever passed across your workbench.
thanks for the retro memories!
C64 reparation is just joy.
Keep going!
GREAT content - well covered.. Thanks
I like all the repairs, C64 or otherwise. It’s very satisfying when you find the issue and I like your process and have applied it to fixed vintage gear myself.
Very interesting and entertaining video. Thank you!
Great job as always Adrian
Love the repair videos!
I love these repair videos. The fact that each C64 suffers from different problems makes these videos ver useful.
I absolutely LOVE C64 repairs, please keep them coming when you can, I can't get enough of them. I have revived mine twice now and it is my original machine from back in 1984 :)
Love the C64 repairs! Keep it up! Like you, I wish for a little more complicated one from time to time, but that's how it is!
Yeah, I like these C64 repairs too. I can pick-up some good info on the custom chips and the general machine architecture. It's all new to me!
This is an absolutely awesome video. Lots of very useful information. At the end, you say that some viewers don't like C64 repair videos but I am of the opposite camp. I subscribed to your channel for the C64 videos. I like your other videos but I only watch them sporadically. I never miss the C64 ones.
yes I want some more C64 repairs love those
repair-a-thons are lovely!
Awesome video. Thanks!
