The task/contract was handed to Intel's Ted Hoff, who looked at the multiple chip designs and conceived instead of a software (firmware) solution running in a 'computer' processor, rather than doing chip layouts and masks and production for a whole bunch of chips dedicated to only one application. Hoff's concept would become MCS-4 family of chips of which the 4004 is the processor. If I have it right, because the MCS-4 family was developed under the contract to Busicom, Intel had to do some business wrangling to get the rights back to their MCS-4 design to sell it as a general-purpose processor independently of Busicom. - ca. early-70s: The 8008 was conceived for use in a Datapoint computer terminal design. Read the story in the past, don't recall the details in as much depth. - ca. late-60s: I don't know about the 4004 being inspired by the F14, perhaps you're thinking of the following: there was a competing claim against the 4004 for title of "first microprocessor" by (the designers of) a processor for fly-by-wire(?) of a fighter jet. It was implemented in LSI, but as I recall, it was constituted from several chips and the delineation of functionality across the chips left the claim of being a single-chip processor, and hence first microprocessor, rather tenuous. -- The 4004 may win the claim of being first (microprocessor), but really it was just an idea whose time had come. The microprocessor was inevitable as continually increasing integration levels reached the point of it being feasible.
