In March of 1975 two great events happened within a few miles of each other in Palo Alto California. On March 1, 1975 at Xerox Palo Alto Research Center (PARC) the doors officially opened on the new main building at 3333 Coyote Hill Road, researchers moved in, and carried on work to build the applications and user community based on their own hand-built Alto graphical personal workstations connected with Ethernet and the ARPA network. Then, on March 5, 1975, Hobbyists met for the first time to form the Homebrew Computer Club to share their experiences with the brand new microcomputer kits and try to figure out how to make them do something useful.
