Somewhere I have the images and software because I've had to do this
once.

Writing? Yes. Reading? Not if you emulate a floppy
controller with your
parallel port. Google "disk2fdi" for a working program.
Disk2fdi is, indeed, remarkable.
(BTW, it does NOT appear to "emulate a floppy controller with your
parallel port"; It appears to be sampling the raw data lines of a disk
controlled by a normal FDC, and using the parallel port to provide some
of the functionality of a "flux transition" board)
Producing a version of it that can WRITE will add a few more
serious complications.
But I still don't believe that APPLE ever provided a way for a
PC to format and write 800K GCR.
