You're in luck.  Apple III's used an operating system called SOS (Sophisticated
Operating System).  It is completely file structure compatible with
Apple ]['s ProDOS, so any file can be read or written to an Apple III disk.
In fact, if you have any 3-EZ Pieces files, they can be read directly
by AppleWorks, since 3-EZ Pieces was the precursor to Appleworks.  Have fun.
