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.

- 72-pin ECC SIMMs
- Takes 8-32 MB modules
- Either 4 (on /60 and /80 models) or 6 (on /100) sockets
- 16 MB (2×8) minimum, 128 MB (4×32)/ 192 MB (6×32) maximum
- Memory has to be installed in pairs, starting from slot 0, which is the closest slot to the drives.
- VRAM expansion slot for:
- A2263-66520M - Video RAM expansion for higher resolutions/more colors
- One slot for a GIO card (special formfactor GSC bus cards, only used in the 712),
with the following cards available:
- A2878A - second video
- A4011A - 8025 Token Ring interface
- A4011B - 8025 Token Ring interface
- A4013A - second serial port
