Project MAC
     
         A project suggested by J C R Licklider; its founding
        director was {MIT} Prof. Robert M Fano.  MAC stood for
        Multiple Access Computers on the 5th floor of Tech Square, and
        Man and Computer on the 9th floor.  The major efforts were
        Corbato's {Multics} development and {Marvin Minsky}'s
        {Artificial Intelligence} Laboratory.  In 1963 Project MAC
        hosted a summer study, which brought many well-known computer
        scientists to Cambridge to use {CTSS} and to discuss the
        future of computing.
     
        Funding for Project MAC was provided by the Information
        Processing Techniques Office of the {Advanced Research
        Projects Agency} (ARPA) of the US Department of Defense.
