Devices included in this entry:

Intel D8086 microprocessor (40-pin ceramic sandwich DIP)
Intel D8088-2 microprocessor (40-pin ceramic sandwich DIP)
Intel C8206 polynomial error detection circuit (82-pin ceramic LCC; pictured in thumbnail)
Intel C8207-2 DRAM controller (82-pin LCC)


Introduced in 1978, the Intel 8086 is the first widely adopted 16-bit microprocessor, and the first implementation of what would come to be known as the x86 architecture. A year after the 8086, Intel released the 8088, an 8086 variant with a 8-bit external data bus. IBM's selected the 8088 as the CPU of their first IBM personal computer in 1981, a decision which would have far-reaching effects to this day. Virtually all modern personal computers are built upon an x86-based microprocessor, manufactured by either Intel or AMD.

The MCS-86 includes the 8086 and 8088 microprocessors, as well as a long list of support devices.
