AMD 8086 microprocessor family

While the Intel let AMD to second-source 8080 and 8085 microprocessors, at first Intel didn't want to license x86 technology. It was one of the reasons why AMD decided to go with 16-bit Zilog Z8000 microprocessors. The situation changed in a few years. In 1982 Intel x86 CPUs were selected for IBM PC computers on the condition that there will be a reliable second-source CPU manufacturer. This helped AMD to negotiate new technical exchange agreement with Intel. The agreement was signed in October of 1981, and it gave AMD rights to second-source 8086 and 8088 microprocessors. The agreement was executed in the beginning of 1982. The same year AMD began volume production of 8086 CPUs.

AMD 8086 microprocessors were fabricated in ceramic DIP, plastic DIP and plastic PLCC packages at speeds 5, 8 and 10 MHz.
