Intel has introduced an integrated CPU complete with a 4-bit parallel adder, sixteen 4-bit registers, an accumulator and a push-down stack on one chip. It's one of a family of four new ICs which comprise the MCS-4 micro computer system-the first system to bring the power and flexibility of a dedicated general-purpose computer at low cost in as few as two dual in-line packages.
