Am8086 (AMD 8086) was a second-sourced 8086 chip designed by Intel and manufactured by AMD in 1982.

History

The 1976 agreement AMD had with Intel covered earlier chips such as the 8080 and 8085. The x86 series was intended to stay exclusively with Intel. The situation changed when IBM selected the x86 series to go in the PC. IBM required all their manufacturers to have a second source. Consequently, in 1981 Intel renewed their 76 agreement. A year later they also signed the technology exchange agreement which allowed AMD to enter the x86 market and later resulted in the legal battles that spanned much of the late 80s and early 90s.

AMD started bulk production of Intel's 8086 in 1982. AMD's 8086 are Intel's own design and are thus identical except for the manufacturing process used.
