1965

DEC unveils the PDP-8, the first commercially successful minicomputer. Small enough to sit on a desktop, it sells for $18,000 — one-fifth the cost of a low-end IBM/360 mainframe. The combination of speed, size, and cost enables the establishment of the minicomputer in thousands of manufacturing plants, offices, and scientific laboratories.


With ARPA funding, Larry Roberts and Thomas Marill create the first wide-area network connection. They connect the TX-2 at MIT to the Q-32 in Santa Monica via a dedicated telephone line with acoustic couplers. The system confirms the suspicions of the Intergalactic Network researchers that telephone lines work for data, but are inefficient, wasteful of bandwidth, and expensive. As Kleinrock predicts, packet switching offers the most promising model for communication between computers.

Late in the year, Ivan Sutherland hires Bob Taylor from NASA. Taylor pulls together the ideas about networking that are gaining momentum amongst IPTO’s computer-scientist contractors.

The ARPA-funded JOSS (Johnniac Open Shop System) at the RAND Corporation goes on line. The JOSS system permits online computational problem solving at a number of remote electric typewriter consoles. The standard IBM Model 868 electric typewriters are modified with a small box with indicator lights and activating switches. The user input appears in green, and JOSS responds with the output in black.
