The MCS-4 or 4000 Series or Busicom Chip Set was a family of 4-bit microprocessor chipsets. The chipset, which was made of four individual chips included the 4004 CPU, the first commercial microprocessor. MCS-4 was completed by March 1971, entered production in June, and introduced into the market on November 15, 1971.
Components
The MCS-4 can be minimally functioning with just the 4001 ROM and the 4004 CPU, however its designed to be fully functioning with RAM and shift register.additionally two more chips, the 4008 and 4009 to expand the system to work with any of Intel's existing memory chip selections.
