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!

@@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 KZfaq 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.

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.

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.

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.

@nakkistromberg3946 3 ай бұрын

@@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.

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.
