Actually, I think most if not all of the MacAddict discs are on archive.org:

I just recently got a nearly complete set of the discs (and the magazines themselves) which I'm intending to scan, since although the discs are on archive.org, nearly none have images of the covers. Getting through the magazines will take significantly longer, but I'll probably have the disc covers done soon.
