Futurebus
Futurebus, or IEEE 896, is a computer bus standard, intended to replace all local bus connections in a computer, including the CPU, memory, plug-in cards and even, to some extent, LAN links between machines. The effort started in 1979 and didn't complete until 1987, and then immediately went into a redesign that lasted until 1994. By this point, implementation of a chip-set based on the standard lacked industry leadership. It has seen little real-world use, although custom implementations continue to be designed and used throughout industry. History In the late 1970s, VMEbus was faster than the parts plugged into it. It was quite reasonable to connect a CPU and RAM to VME on separate cards to build a computer. However, as the speed of the CPUs and RAM rapidly increased, VME was quickly overwhelmed. Increasing the speed of VME was not easy, because all of the parts plugged into it would have to be able to support these faster speeds as well. Futurebus looked to fix these proble ...

DEC 7000/10000 AXP
The DEC 7000 AXP and DEC 10000 AXP are a series of high-end multiprocessor server computers developed and manufactured by Digital Equipment Corporation, introduced on 10 November 1992 (although the DEC 10000 AXP was not available until the following year). These systems formed part of the first generation of systems based on the 64-bit Alpha AXP architecture and at the time of introduction, ran Digital's OpenVMS AXP operating system, with DEC OSF/1 AXP available in March 1993. They were designed in parallel with the VAX 7000 and VAX 10000 minicomputers, and are identical except for the processor module(s) and supported bus interfaces. A field upgrade from a VAX 7000/10000 to a DEC 7000/10000 AXP was possible by means of swapping the processor boards. The DEC 7000/10000 AXP were intended to supersede the VAX 6000 series, and themselves were succeeded in 1995 by the AlphaServer 8200 and 8400 (''TurboLaser'') enterprise servers.
