I think most large organizations created their own default environment. When I started college in 1993 we had a mix of Sun, DEC, HP, IBM, and SGI workstations.

I think most large organizations created their own default environment. When I started college in 1993 we had a mix of Sun, DEC, HP, IBM, and SGI workstations. They all had a basic environment with mwm and menus configured for popular programs. Someone introduced me to vtwm and the concept of virtual desktops and I loved it. I remember spending hours in the computer lab tweaking my .vtwmrc file and showing it to friends.
