Intel 8086 story

The Intel 8086 project started in May 1976. The 8086 design was expanded to support full 16-bits processing. Its architecture was defined by Stephen P. Morse. This CPU had a more software-centric approach than in the design of earlier Intel processors and was compatible with various family languages.

The 8086 was released in June 8th, 1978.
A derived version, the Intel 8088 (External Bus recuced to 8-bits), was released in June 1st, 1979.

The 8086/88 family gave rise to the x86 architecture, which became Intel's most successful line of processors. Compatible versions were manufactured by Fujitsu, Harris/Intersil, OKI, Siemens AG, Texas Instruments, NEC, Mitsubishi, and AMD.
Any assembly-language program written as far back as 1978 for the Intel 8086 microprocessor will run, unmodified, on Intel’s latest Core i9 Extreme CPU.
