Intel 4004 turns 50

The Intel 4004 was Harvard Architecture, as were the four bit microprocessors that came later. (TI's TMS-1000, National Semi's COPS, Rockwell's PPS4) Fine for a fixed program calculator or microcontroller, but the von Neumann 8 bit microprocessor IC's opened up vastly more advances in low cost computer hardware and software.
