Consider that, at 250Kb/sec and 300 rev/min, a "720K" diskette has a
capacity of 6250 byes/track (that's raw, not accounting for gaps,
address marks, CRCs or any of that nonsense). Such a diskette has
160 tracks, so we get 6250*160 = 1 000 000 bytes. For once, the
label tells the real truth. How you want to format those million
bytes is your problem. ;-)
