If the disks are w~hat I think, it's not only possible, it's very easy.

Xenix's device driver for the floppy can handle any combination of
1 or 2 sides, 40 or 80 tracks, 8, 9 or 15 sectors per track.  They have
devices for all these.  In your case, you want /dev/rfd096ds9 or rfd096ds8
depending on how many sectors per track.

I use the 96ds9 device for all my backup and TAR work.  It's 720K but it
works just fine on cheap floppies, so you don't have to pay 5 times the price
for 1.2 meg ones.

Now, somebody should write a 720K DOS device driver for the AT!
