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.
