Abstract:
Ted Hoff and Stan Mazor describe their work on the design and development of Intel’s first microprocessor family the MCS-4 in the 1969 through 1972 period. As manager of Applications Research, Ted suggested redesigning a set of one dozen custom logic circuits for Japanese calculator manufacturer Busicom into a more flexible general purpose solution using fewer expensive packages. He hired Stan Mazor from Fairchild to help configure the architecture around a 4-bit CPU (the 4004). They describe the process of developing the logic design in association with the customer engineer, Masatoshi Shima, and working with Federico Faggin who translated their concept into four MOS silicon gate integrated circuits that today is recognized as the first commercial microprocessor chip set. This panel was convened to supplement information on the Intel 4004 development included in the "Oral History of Federico Faggin" recorded at the museum in 2004 and a forthcoming contribution by Masatoshi Shima.
