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.

The rarest 4004s are the grey trace with a black dot, instead of the gold dot for pin one. I have two grey trace but with gold dot. I believe these are older than the grey trace with black dot. Although, as originally sold, the 4004 was a Harvard architecture, it could be made to be, easily, made to be a von Neumann machine with either a 4008/4009 set or a 4289. I don't know if that was ever done, other than for the Mod 4 development machine. The 4004 had no interrupt but the later 4040 did.
