HP-UX (English Wikipedia)

Wang, Scott W. Y.; Lindberg, Jeff B. (March 1984). "HP-UX: Implementation of UNIX on the HP 9000 Series 500 Computer Systems". Hewlett-Packard Journal. 35 (3): 7–15. Retrieved 4 October 2020. The basic strategy of the HP-UX implementation is to layer the HP-UX kernel definition on top of the SUN kernel. The exact System III UNIX semantics and syntax are kept, but the HP-UX intrinsics are implemented using SUN kernel support instead of porting the Bell Laboratories kernel implementation to the Series 500.
