5.25 Inch Floppy Cut with Xacto (5.25 in x 5.25 in). Still working my way through outdated media types (thanks again to Kim in Australia for sending me the floppies!). What formats have I missed?
Floppy Discs Cut with Scroll Saw. Being a Mac user I'd basically forgotten about these things, since we haven't had a drive for them in a long while. But I was reminded when I saw one on the street the other day and happily I found that I had actually stored a few of my old ones.
