>In the late 1970's Microsoft licensed UNIX source code from AT&T which at the time was not licensing the name UNIX. Therefore Microsoft created the name Xenix. Microsoft did not sell Xenix to end-users but instead licensed the software to software OEMs such as Intel, Tandy, Altos and SCO who then provided a finished version of their own Xenix to the end-users or other customers.

>SCO introduced its first version of Xenix named SCO Xenix System V for the Intel 8086 and 8088 in 1983. Today SCO Xenix is one of the more commonly used and found versions of Xenix.
>>I think there is even a version of Xenix somewhere on one of my old MSDN subscription disks. Or was it REXX ... ?
