The first thing I did was to see if there were any distros I could remember that weren't listed... The first is Finn linux (or was it Fynn or Flynn?) that was an early attempt at a commercial distribution. I recall some ads in computer mags around '94 or '95 and it was fairly expensive (several hundred). Obviously it never went anywhere.

The other is the Linux Router Project which was a router/firewall distro that would fit on a 3.5" floppy disc. (http://en.wikipedia.org/wiki/Linux_Router_Project) I actually used it and was disappointed that it didn't really go anywhere. It was nice to be able to back up your firewall by copying a floppy disk :)
