MicroBurn told me something interesting. MicroSoft actually sold a UNIX variant, and even owned part of SCO for a time.

Maybe you all know this already, but had to get it here.


"Microsoft announces Microsoft Xenix OS, a portable operating system for 16-bit microprocessors. It is an interactive, multiuser, multitasking system that will run on Intel 8086, Zilog Z8000, Motorola M68000, and DEC PDP-11 series. All of Microsoft's existing system software (Cobol, Pascal, Basic, and DBMS) will be adapted to run under the Xenix system, and all existing software written for Unix OS will be compatible as well. "
