I did find one unimportant error,
He said that DOS 1.10 supported both double sided, and 9 sectors per
track.
That may have been what he wished for, but I'm pretty sure that what
Microsoft actually released was DOS 1.10/1.25 supported double sided 8
sectors per track (up from single sided in DOS 1.00),
(SOME OEM versions of 1.25 support 8" disks!)
and DOS 2.00 supported 9 sectors per track (Plus enormous other major
changes, such as the "file handle" API, added to the existing "FCB"
API.
