Does anyone know if it would be possible just to read in the raw (i.e. Woz
encoded) data using the PC FD controller and then massage the sectors in
memory so that they can be used?  After all, this is pretty much what both
DOS and ProDOS used to do with their translation tables.  The only question
is: can the FDC read the Apple II disk at all (is it physically possible to
read the data from the disk maybe even with address/data headers still
embedded)?
