I might be able to help you a little bit on this. In
the late 1970s
and early 1980s a number of Canadian universities built V6 systems
for PDP 11/23 based systems. These systems were relatively cheap
and were great for teaching and some research. At the University of
Toronto we build at least three systems for the undergraduate
database course, and when I moved to McMaster University I built two
for project courses. With some modifications to the kernel an 11/23
could support 6 or 7 students working on programming projects.
I suspect the UBC system that you picked up served a similar purpose.
Any idea who might have a copy of the modifications to the V6 source to
support RL02's? It'd be wonderful to put that into the PUPS archive.
This particular V6 system is indeed a very nice environment for someone
with a "small" 11/23 and RL02 drives.
That particular 11/23 system from UBC was used in the biology department,
judging by the non-system files found on the "user" disk.

The base system may have started out at UBC's CS department, or it
may have come from Zoology at UofT. Henry Spencer would definitely
know about the V6 mods we made at UofT (he may even have been
involved, but my memory isn't that good anymore).
