I enjoy watching someone who knows what they are doing, tracking down issues and resolving them like this. Thanks for making videos like this so we can learn as well. Much appreciated.
Thank you for this series, I love C64 repairathons. I also repaired a bunch of them in the past months, but I am not as kwoledgeable as you. I wonder where all those computers end up in your case, whether they stockpile in a closet like the ones I repaired. From time to time I could turn them on, checking if they are still operational and maybe hoping that I have to fix them again! 😄
You're welcome and thank you for watching! My intent is to resell them, but I'm REALLY behind on cleaning up the cases and restoring the keyboards, so they're all sitting in piles in my lab getting in the way. I love the idea of putting these back into the world and letting others enjoy them.
Thanks, Donald. Honestly, I could probably have revived the 466, but the cost to replace all those IC's would be prohibitive. Yes, it's great that I could salvage the R9. Thanks for watching and have a great weekend yourself!
Hi bud, hope I don't disturb your Sunday. If the 466 board was mine... I would still tinker away with it... even if I had to gut chips from a 407 board... so curious on how many more bad chips there are left 🤔. I would buy it as is. And don't worry. I know I'm crazy 🤪. Lol
Hi, Donald. No, you're not disturbing me. I'm considering making a special video for channel members only where I continue to strip that board until I clear the short, then rebuild it just to see if I can get it working again. I figure a full set of replacement ICs (based on what I'm seeing on ebay right now) would run me about $250 (assuming I have to buy a VIC-II because I've used the original in another repair). That's too much to spend on one C64, so if I do it, I'll probably just use parts off other boards I have on-hand and take them back after I'm done, just for the exercise and fun of seeing if I can do it and the entertainment value to the viewers.
Hey bud. Relating back to where I asked you where I can find color ram chips.... I remembered I bought 2 full ram replacement kits a couple years ago . In this kit.. there is a AM9114CPC chip. Is that a replacement for the 2114 color ram chip? I never knew... but it is 18 pin as well. Hmm
It could be. I think I may finish stripping that board down and testing the parts on a members-only video and see if I can rebuild it. It'll just be temporary because I can't afford that many spares, but it would be interesting to see if it can be done. Thanks for watching!
I wondered the same. I think there was a little overlap where 466's were put into breadbins before the wedge cases started being used, but I'm not sure. Otherwise, it's just a Frankenstein. Thanks for watching!
@@YARC-1981 I bought 2 C64 bread bins and one was a 466. Both were working and I sold the 466 on. Both of the power supplies worked but I bought a modern replacement supply from Poland for the 425 I kept. I should have kept the 466 because it had better video output. The 425 has a weird cocks-comb pattern to the color areas on the screen, especially browns and yellows.
Wow! Carnage indeed. In my mind, this is beyond a feasible repair. I would make it a donor board, all mechanical parts like the switch, ports, etc. may have a new life in an otherwise poorly board. You haven't tested the 8701 clock generator on camera, but most probably that will be fine too. RAM ICs and color RAM are worth desoldering and testing (most probably futile work) but the logics etc are not worth the effort.
I agree. Under normal circumstances I wouldn't try to finish that repair. I'd just use it as a donor. In this case, though, I'm considering making a video exclusively for channel members where I do actually strip it down, test the remaining parts and then try to rebuild it, just for the exercise and the fun and entertainment value for the viewers. It would be interesting to see if I can find all the shorted components and get it running again.
@@YARC-1981 Yes, that would be a fun video to watch. You can attach a non-current protected (but current limited to around 1A to prevent a smoke and fire show) 5V PSU to the 5V line and see which ICs get hot very quickly. That would be a good starting point to find the shorted ones.

HA! Fooled you. I'm winging it. ;)
Kidding, of course. Thank you for the compliment. You're gonna make me blush.
That "Brick of Death" racked up the kills. I lost a 6581R4 to a faulty PS too. It was not a happy time.
I feel you. I was so disappointed the R4AR was nuked. Thanks for watching!
I don't think Tramiel imagined the C64 lasting this long!
No, but I bet he'd be chuffed, if he knew. Thanks for watching!

Nice work bud 👍. Very sad to see the beloved 466 board be so bad:( awesome that the 6567R9 is good though. Enjoy the rest of your weekend. Cheers

Perfect. Can't wait. That 466 always has great video output... just with composite. I'd rob a 407 board any day to fix the 466.

NIce repair, maybe that clock generator was warking maybe :)

The last time a certain Number 5 got hit by what you could call overvoltage, it had an unexpected, but rather nice effect...
"Life is NOT a malfunction!"
I wonder how that 250466 motherboard ended up inside that breadbin. It was good to see you working with one of those.

@@borayurt66 Good idea. I should have thought of that.
