To be fair, we had not and have not stipulated what we mean when we say "floppy". Maybe you were a rich kid but a lot of us were still on some pretty low density stuff into the late 80's. Embarrassingly, I was still on cassette for most of the decade.
There is no PC, Mac, or Amiga floppy drive that could not have held the tfile Anarchist's Cookbook (the tfile cookbook is not the same as the book, which fits easily on a single-density 3.5 but not on a 5.25).
