But : it is ancient. http://www.sxlist.com/techref/intel/8086.HTM: "Intel introduced the 8086 and 8088 microprocessor extensions to the 8080 product line in 1979." http://www.sxlist.com/techref/intel/80186.HTM: "Intel continued the evolution of the 8086 and 8088 by introducing the 80186 and 80188." http://www.sxlist.com/techref/intel/80286.HTM: "In 1982, Intel introduced the 80286."
