In 1974, IMS was contacted by a client which wanted a "workstation system" that could do jobs for any General Motors new-car dealership. IMS planned a system including a terminal, small computer, printer, and special software. Five of these work stations were to have common access to a hard disk, which would be controlled by a small computer. Eventually product development was stopped. Millard and his chief engineer Joe Killian turned to the microprocessor. Intel had announced the 8080 chip, and compared to the 4004 to which IMS Associates had first used, the 8080 looked like a better idea. Full scale development of the IMSAI 8080 was begun, and by October 1975 an advertisement was placed in the magazine "Popular Electronics", receiving positive reactions.
