There were also a number of smaller players in this space.
Hell, Linux
didn't exist at all till '91.
I think Xenix was more just a casualty of the Unix Wars. The victors there
were SunOS/Solaris, AIX, and HP-UX. There were a bunch more walking
wounded that never really achieved much market share.

machines on which it was installed.'
