The Intel 8086 is a 16-bit microprocessor chip, an enhanced version of the Intel 8085, by Intel Corporation in early 1976 and began manufacturing shortly afterward; it was released to retail on June 8, 1978. Systems utilizing this processor can sometimes also take advantage of an additional Intel 8087 or Intel 8089 numeric co-processor. The Intel 8086 was advertised as "source-code compatible" with the Intel 8080 and Intel 8085, but was not object-code compatible. The Intel 8086 would later be cloned by other manufacturers, such as AMD, Fujitsu, Harris Corporation, OKI, MHS, Mitsubishi, NEC, Siemens and the Soviet Union.
The development of the Intel 8086 was critically important, as the underlying x86 architecture was used by IBM in their original IBM PC design when it chose to use the 8-bit Intel 8088 as the foundation of the system.
