Version History:

Superceeds MS-DOS 3.20. This release was one of the fastest non-OEM updates Microsoft ever put out, taking only 9 weeks of development time. It addressed issues with the keyboard layout files and graphics controls. There were also maintenance updates and additional command-line switch options added to a number of files, as reflected in the small increase in file size between the two versions. This release also had the distinction of shipping in the largest packaging, with the outer box cover measuring 11" wide, x 10" high, x 6" deep.
