The Heriot-Watt University in Edinburgh had some 68K CADMUS systems,
which included a number of standard QBus boards and yes the OS was
virtually 7th Edition. When I got my 11/23 system (running real
standard 7th edition, and including the original tapes) form them, I had
a play with a CADMUS system. it was quite a nice system, but one
problem was that the quad-high CADMUS boards didn't have the same sort
of stiffeners along the back edge that DEC boards do, so they sagged and
had an occasional tendency to short out.
