The argument was that serious computers like VMS or the like ran real databases and without file locking UNIX would never be considered a real OS that people could use. BTW: Joy would later use Bass's call as a model for the 4.2 call, but Joy made the locks advisory, Bass's version was full / mandatory locks.

As I remember the Z8000 was going to be the great white hope that
would continue Zilog's success with the Z80 into modern times.
But, it obviously didn't happen.

Why?
