4K/track * (35 tracks/disk - 4 tracks overhead + track 35) = 128K-- the usable
capacity of most of my disks.  (Why Woz didn't include track 35 in unmodified
DOS I don't know).
But, even this is incorrect-- When I bought my Apple, it had DOS 3.2-- the
only 16 sector disks were Pascal.  So it was
1/4K/sector * 13 sectors/track * (35 tracks - 4 tracks overhead) = 100.75 K
