Advanced Micro Devices, Inc. (AMD) introduced the Am2901 4-bit-slice, the first member of its Am2900 microprogrammable microprocessor family in 1975. Implemented in Low-power Schottky TTL process technology, the device offered significantly faster speed than contemporary MOS products and became an industry standard product with numerous alternate sources. It found wide application in minicomputers, disk drives and other high-performance computing and communication systems and remained an important source of revenue for AMD for more than 20 years. This oral history includes key personnel responsible for the applications, design, manufacturing, and marketing of the initial members of the family.
