Overview

Project names:

The 735 and 755 are early-1990s technical and graphical workstations and computing servers. Both 735 (desktop) and 755 (tower) have a very solid and heavy casing and are built with several circuit boards, seperate 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 one of the fastest RISC workstations running NeXTSTEP.

The 735 is built into a similar case to the HP 9000/720 workstations, and the CPU and I/O boards can be swapped between them (however only together).
