The design of Coherent called for rigorous compatibility with Bell Lab's
UNIX Version 7.  In this regard, the project was a success.  With the
breakup of AT&T, the anti-trust obstacles to that company's entry to the
computer market were removed, sealing Coherent's fate.

Coherent was the operating system for Commodore's ill-fated C900.  The two
people who instigated Amiga UNIX worked on the original Coherent, back in
Chicago.
