"HP-UX had a good run, after a long and very varied history. The first version ran on the HP 9000 Series 500 range of 32-bit machines based on the HP FOCUS multi-chip CISC processor. In 1984, the Hewlett-Packard Journal ran a detailed article on how that port was created, based on a kernel called SUN - not related to Sun Microsystems' SunOS."
"The Bitsavers site - run by Al Kossow, who recently recovered UNIX V4 from a 52-year-old tape - has a scan of HP's 1985 brochure [PDF]. Then came a Motorola 68000 version, which ran on top of an AT&T Unix kernel, unusually stored in a ROM chip, in HP's pioneering portable Unix workstation, the HP Integral PC [PDF]. After that, it was rewritten again for HP's own in-house RISC architecture, PA-RISC."
HP-UX 11i v3 reached end of standard support on 31 December 2025 and is now classified as a mature software product with no sustaining engineering through at least 31 December 2028. The last identifiable release is HP-UX 11i v3 release 2505.11iv3, issued on 22 May 2025 for HPE Integrity servers running Itanium processors and NUMA. Some observers noted the end-of-life and vendors such as SUSE positioned Linux as an alternative. HP-UX originated in 1982 and evolved across multiple architectures: HP FOCUS CISC, Motorola 68000 on AT&T Unix, and later a rewrite for PA-RISC RISC architecture.
