As a random aside, color me not getting why you wouldn't want to run OS 8+ on a machine capable of it. You *really* should be using HFS+ on modern-size disk drives, and that includes USB thumb drives. Plain HFS has the same limit as DOS FAT16 on the number of allocatable blocks so you start wasting a *lot* of space (assuming you're storing small files) once your disk sizes get into the gigabyte range.
