An earlier bus architecture from Intel used in industrial, military and aerospace applications. Introduced in the 1970s, there were many MULTIBUS products offered by the mid-1980s. MULTIBUS was later acquired by RadiSys Corporation and then U.S. Technologies, Inc. It was also adopted by the IEEE as the 796-1983 IEEE Standard Microcomputer System Bus, but IEEE withdrew the standard in 2015. MULTIBUS I (16 bits) and MULTIBUS II (32 bits) include message passing, auto configuration and software interrupts. See
