Overview

Project names:

The HP 9000 735 and 755 were technical and graphical workstations from the early 1990s in a powerful configuration. They used the 32-bit PA-RISC 1.1 PA-7100 or PA-71500 processors, the latter in the fast (and expensive) 735/125 and 755/125 configuration. Both 735 (desktop) and 755 (tower) have a solid and heavy desk-side case and are built with several modules, separate for I/O and CPU. These boards, along with EISA cages and the storage subsystem are built into so-called sliders that can be removed separately from the system. They support a large set of I/O buses, expansion options and drives. The 735 was widely used as a FDDI node in Convex clusters and as 735/125 one of the fastest RISC workstations running NeXTSTEP.

The 735 and 755 have similar cases to their PA-7000 predecessors HP 9000/730 and 750.
