It would be well to remember that, back when hard-sectoring was common, it
was considered more efficient than soft-sectoring. Shugart 801 drives were
certainly available with hard-sector support as an option. Hard-sectoring
did cost more, hence died off quickly enough.
SInce this stuff is source code, if you have the ability to read it with one
or another ancient system, it might be well to look at the source files to
see what kind of FDC was supposed to be used.
