One big problem with using a 1.2MB 5.25 inch floppy drive is that the head
steps at a finer resolution (96 tracks-per-inch I believe). A 5.25 inch CoCo
floppy has 48 tracks-per-inch, so VCC would need to step the head twice for
each track. This might work for READING CoCo floppies, but if you WRITE to
the disk, it only writes on 1/2 the width of the track. This could make the
disk unreadable on a CoCo 5.25 inch drive.
