Overview

The HP 9000/715 range of computers were technical PA-RISC workstations from HP in the early 1990s. They were powerful, expandable HP-UX systems that were often used for technical design, CAD/CAM and engineering. Various configurations were available in two different technical families:

The 715/33, 715/50 and 715/75 were the first 715 series, with PA-7100 processors and ASP, the original chipset/mainbus.
The 715/64, 715/80, 715/100 and 715/100XC were newer, based on the modern LASI design, and were technically close to the 712 workstations.
