I was into the SID music more than the demos. Although, I guess the self-playing songs were "demos" in a certain sense. I do, however have the Commodore Christmas demo on diskette! My dad would come home with something interesting from his Commodore Users Group each month. There might be a few demos scattered over the "MISC" category disks.

I too, still have the C=64 with two 1541s. I never "modded" the 2nd drive to have its own address, it was just a backup. We also had a typewriter that doubled as a daisy-wheel printer in what appeared to be a really kludgey setup that actually worked.

I'll see if I can find the old disks and see what turns up on them. I'm not too sure how I would bridge the gap from the C=64 to modern PC. I suppose old school null modem would do the trick, albeit s...l...o...w...l...y...
