You could at least pull the data if you wanted, you just need to find a working 5 1nd 1/4 drive then you could pick this adapter or one like it. Though this site looks a little less than super secure, so maybe use a gift card or something.

Ok, so, not sure if I entirely trust that site, but, that is actually still VERY intriguing. I'll admit a bit steeper than I'd expected in price, but, I guess it's a niche product. And, they provide the software for multiple platforms. Hard to argue with that.
I do have some C64 disks in a case in my basement. Mostly programs I'd written myself, if I recall correctly, though there's other stuff. The disks haven't see a drive in something like 25 years, though. The other floppy case with the games disks is gone forever, unfortunately, along with my Loderunner levels.
Oooh, and I still have, in original box with all the accessories, Ultima V. Sure, I know it's out there in emulator world, but it would be amazing if my original disks still were readable.
