In the early 90s the DEC 4000 model 710 AXP was a member of the DEC 4000 AXP family aka "cobra" (including the model 610, 620, 710, 720) which was based on the Digital's Alpha AXP architecture and the IEEE's Futurebus+ profile B standard.

This family was the output of an initiation in Digital to built the industry's most cost-effective and highest-performance departmental server computing system. To achive this goal Digital changed over from VAX CISC to Alpha AXP RISC architecture, and from Q-bus I/O system to Futurebus+. The DECchip 21064/21064A microprocessors were some the first microprocessors implementing the Alpha AXP architecture.

The True64 Unix v5.1 has buried the old Alpha systems. It was the last release which supported those old system buses, like TurboChannel in DEC 3000 series and Futurebus+ in DEC 4000 series.
