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.
