Intel 8088

The Intel 8088 ("eighty-eighty-eight", also called the iAPX 88) is a microprocessor introduced by Intel in June 1979 as a lower-cost variant of the Intel 8086. It uses the same 16-bit registers and instruction set as the 8086, but has an 8-bit external data bus; the two processors can run the same software. The 8088 was used in the original IBM PC and in IBM PC compatible clones.
