I was at Logicon - we inherited some of that - including the PWB install - when we continued their KSOS work.

That would have been around 1982-1983; when I got there the KSOS work (hosted on PWB) was already underway.

If I could find that darned Modula compiler - I've got the original KSOS source code for PDP-11.

I've mentioned this before. We had PWB at Ford Aerospace in
the late 1970s. This was in the group that Mike Padlipsky and
John Nagle were part of.
