I guess I'm a total anorak, but there was a
TNIX..
[Tektronix Unix, running on a PDP11/23-based development sustem]
I own one of
those and BTW I am looking for software for it. The
hard
disk needs a fsck(8) and this is a stand alone tool. Unfortunately I
didn't get those floppies with the machine.
I _may_ have the distribution kit for my machine I will see what I
can find.
