Harking back to the good old HP9000 workstation, and HP-UX, during my time at HP..    The ‘Common Desktop Environment’ (CDE) has now been open sourced, with (apparently) good old Motif to follow soon..      It may have been ugly by modern standards, but still better looking by far than Windows 3.0…

Some of this became part of the OSF (Open Software Foundation) project, with OSF/Motif etc etc.. in the early ’90s..    I still have a set of their ‘white papers’ in a box, somewhere in storage..

– shame that they can’t spell ENVIRONMENT!
