Maybe I need to dig into my floppy drive stash and do some testing.  I
don't have many real 720K drives (1.44M drives work fine in their place
if you use 720K media -- which is also getting hard to find) but I have
quite a few 360K and 1.2M 5.25" drives, most of which should still be in
good working order.

Could one use a 1.2M drive (with HD media) as a 720K drive on a CoCo?
