Overview

The design goal of the 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 was kept simple, the case is one of the smallest Unix workstation cases, similar to the Sun SPARCstation 10 and 20 cases. 712s are very quiet, the fan of the power supply being almost not audible — the produced noise depends on the installed SCSI drive.

Introduced: early-1994 to mid-1995 (712/100)
prices from $4,000 (712/60) and $8,820 (712/80) to $15,100 (712/100).

Internals

CPU

  1. The 1 KB on-chip L1 cache is not really a true cache.

External connectors

  1. The system automatically detects the used port.
  2. You can connect almost any monitor to the VGA jack. The 712 can drive VESA compatible multisync, HP fixed-frequency and many other popular FF monitors. It also is able to produce sync on green signals.

ROM update

There is an firmware update available for the 712, which contains the latest version (2.3).
