Overview

Project name:

These machines were the first PA-RISC workstations, called the Snakes, and were based on the first PA-RISC 1.1 processors. They were built into very solid cases, consisting of interlocking exchangeable modules (sliders). The storage subsystem has its own slider, connected to the main I/O board with a short external cable. The 720 and 730 share the same backplane and I/O board and can be upgraded through the exchange of the CPU board. Later HP 9000/735 workstations share a similar system setup and 720/730 CPU and I/O boards can be swapped together for 735 boards, and vice versa (as 735 I/O boards do not work with 720 CPU boards, both boards have to be exchanged).
