8088 CPU

A variant of the 8086. the 16-bit bus was reduced to 8-bit and some other simplifications made to try and reduce the complexity of the attached circuits it connected too. The CPU itself was not a significant cost reduction but allowed from cost reduced motherboards with 8-bit and 4-bit support and data chips rather than 16-bit and 6-bit components. It still addressed 1 megabyte, like the original. The original IBM PC was based on the [email protected] MHz (The IBM 801 and Motorola 68000 were favored for power but the 8088 was all kinds of cost reduction including licensing fees and overabundance of 8-bit components).
NEC made the V20, an 8088/80186 compatible CPU and continued to make 8088 compatible CPUS that were eventually clocked as high as 16 MHz.
