The design goal of the 32-bit HP 9000/712 workstation was to reach performance levels of 1992-era workstations and servers, for instance HP 9000 735 workstation, at a fraction of their fabrication costs. Everything is rather simplified and small, the case is one of the smallest Unix workstation cases, similar to the Sun SPARCstation 10 and 20 cases. The 712 became hugely popular in technical disciplines as well as in graphics, software and early multi-media development, and also re-sold well on hobbyist markets.
