The LSI-11 was a family of 8-bit multi-chip microprocessor developed jointly by Digital Equipment Corporation and Western Digital. The LSI-11 was DEC's first large-scale integration project and was introduced to the market in 1975. The chipset was manufactured by Western Digital in nMOS technology under a $6.3M contract. Originally designed for the PDP-11, Western Digital later re-branded it and sold it separately as the MCP-1600 which ended up being used in numerous other systems. The MCP-1600 went on to influence the design of other MPUs such as General Instrument's CP1600 microprocessor.
The PDP-11 only needed 4 chips for a complete minicomputer system. The 3015 added the extended instruction set capabilities.
