XENIX for the PDP-11 was available in the UK from the Software Products
of Logica (which in late 1986 was acquired by the Santa Cruz Operation
their UK and European office).
As far as I know it was entirely based on V7 - other than adding a few
and configuring the system to match the customer's hardware I don't
think that either
Microsoft or Logica really did much to the PDP-11 version. I used XENIX on a
PDP11/34 back in (I think) 1982 and most of the work was in finding a kernel
configuration which both had all of the drivers that we needed and would
fit on a
non split i&d machinne.
I don't believe that any System III code showed up in XENIX until
in the Motorola 68k and Intel x86 versions.
