[sebhc] Hard-sectored disks

After all these years, our memory becomes more volatile! If mine is still
functioning correctly, I seem to remember that Micropolis made a floppy
drive that used 16 had sector disks. The version I am thinking about was
designed to work with an S-100 bus system - kind of generic. When I first
got my H89, the floppy system was not yet available, so I bought a
Micropolis package and was going to adapt it. However, the drive mechanisms
were not as good as I had hoped for, so I gave up the project and returned
the drives to the vendor (cost me a restocking fee).

I pinged Herb and he says he will fix the Apple-II reference.

He also says he thinks the Exidy Sourcerer used 16-sector disks, but like me
can't think of any other systems off the top ... they were not nearly as
common as 10-sector disks.
