One of the neater aspects of HP-UX is that, given the breadth of pre-2000s HP, HP-UX ran on a number of different devices. You can almost (_almost_ - it's a stretch) think of it as a precursor to how Linux proliferated on routers and smartphones.

While you'd _expect_ to find HP-UX racked in a datacenter, you can also find it on workstations, where its proprietary VUE desktop environment eventually morphed into CDE (which, ironically, I've only ever used on Solaris).

It powered at least one early, pre-laptop-form-factor portable PC, the HP Integral. And you can also find it running on oscilloscopes, logic analyzers, and other test equipment from the 80s and 90s.

I really liked VUE so much more. The collaboration with IBM really made CDE more business-like and boring.

I still run 10.20 on my old PARISC box for that reason.
