These disk images were dumped and verified as authentic.
Note that there is another 1.03 disk set with a later USER.EXE. The
08-21-86 disk set contains a USER.EXE dated 5/22/86 with a file size
of 122,416 bytes. It is believed that the later version was a last
minute update included on later retail disks, but possibly omitted on
some early retail and/or OEM disks. (This set is reportedly identical
to a Tandon OEM Windows 1.03 set)
