Historical Note
---------------------
I am pretty sure that the FAT file system was developed entirely by
Microsoft - neither Intel nor IBM had any hand in its design. It is
possible that Microsoft got the basic design of FAT from Seattle
Computer Products, from whom they purchased SB-DOS and re-worked it
to be MS-DOS 1.0.
As I recall Bill Gates was personally credited with much of the
technical design of FAT.
This information is from my memory, which is neither ECC nor Parity,
but is still "PGM" - Pretty Good Memory.
