Overview

The E-Class Wright Brothers are low-cost PA-RISC servers from the mid-1990s and replacements for the older F and G-Class Nova servers. Designed for reduced manufacturing cost they were developed in parallel to the HP 9000/712 workstations. The case was taken over almost unchanged from the F-Class, with the CPU/memory and part of the I/O systems being new designs. From the integrated LASI chipset only the networking and several other functions were used — due to time constraints a modified version of the F-Class HP-PB Personality boards was used for SCSI, serial MUX and parallel.
