I have a Powerbook G4 OSX 10.5.5 but want to read floppy disks from an ancient Mac that only has OS3. (The programme was Works 3.0a.) Apple told me first that I just needed a compatible floppy disk reader, which I have, then, when I couldn't open files, that I needed i-Works, though it still might not work. I couldn't download the free trial as it said my - newer - computer was too old.
