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.
