Intel's 4004 Microprocessor Turns 45
mcpublic writes: Tuesday marked the 45th anniversary of the 4004, Intel's first microprocessor chip, announced to the world in the November 15, 1971 issue of Electronic News . It seems that everyone (except Intel) loves to argue whether it was truly the "first microprocessor"... But what's indisputable is that the 4004 was the computer chip that started Intel's pivot from a tiny semiconductor memory company to the personal computing giant we know today. Federico Faggin, an Italian immigrant who invented the self-aligned, silicon gate MOS transistor and buried contacts technology, joined Intel in 1970. He needed both his inventions to squeeze the 4004's roughly 2,300 transistors into a single 3x4mm silicon die. He later went on to design the Intel 8080 and the Zilog Z80 with Masatoshi Shima, a Japanese engineer with a "steel trap mind," the once-unsung hero of the 4004 team [YouTube]. Long-time Slashdot reader darkharlequin also flags the " fascinating, if true" story of Wayne D. Pickette, who was hired by Intel in 1970, worked on the 4004 project, and according to ZDNet "claims that prior to that, during his job interview with Intel founder Bob Noyce, he showed the company a block diagram of a microprocessor he'd started to work on three years previously when he was 17."Read more of this story at Slashdot.
