Between 1972 and 1980, the first distributed personal computing system was built at the Xerox Palo Alto Research Center. The system was composed of a number of Alto workstations connected by an Ethernet local network. It also included servers that provided centralized facilities. This paper describes the development of the hardware that was the basis of the system.
