Single Floppy Unix Clones For Mac?

tangsoodo asks: "It's easy to find 1 floppy Linux distributions like Tomsrtbt or Trinux, but they seem to only run on PC's... are there any 1 or few floppy distributions of Linux or even a BSD that run on 68k or PPC Macs? Yes, I know new Macs don't have floppy drives, but there are tons of older Macs still being used in schools and libraries, and running off a floppy is probably the easiest way to experiment with the Unices without messing with the hard drive."
