Overview

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

The HP 9000 715/33, 715/50 and 715/75 were the first 715 series with PA-7100 processors and the original HP ASP chipset.
The HP 9000 715/64, 715/80, 715/100 and 715/100XC were more modern and based on the LASI chipset design, technically close to the HP 9000 712 workstations.
