[TUHS] Classic Unix workstation GUIs

[Ronald Natalie]

Amusingly the hardware between the 9000 and 3000 line are the same.   The 9000's were marketed with HP/UX.
The 3000's ran MPE (or as we called it Mighty Poor Excuse).    I had an HP/UX machine back when I was consulting
with Unipress back in 87 or so (and then we did a lot with them in my later job when the newer systems came out).
But I'm trying to remember a pre-X windowing system and can't think of it.   The later HP/UX had an their own proprietary
Motif-based window manager.
