That page is a bit too much marketing fluff for my linking. A couple other interesting pages on the 4004: * An oral history from the developers [1]. One interesting part is that Intel procrastinates for months on developing the chip. Faggin gets hired to work on the chip, and Shima flies in from Japan the very next day to check on progress. He's very upset to find out that nothing has happened and starts yelling at Faggin, who just got there. They eventually work together to get the chip finished. * Federico Faggin's website [2] with his perspective on the chip.

This chip's architecture and instruction set was basically identical to the 8008 (since both were copies of the Datapoint 2200). Texas Instruments patented the TMX-1795 (which was a hugely valuable patent) and then abandoned the chip because it didn't work well.
