![]() This is likely the first example of remote access computing. Stibitz stunned the group by performing calculations remotely on the CNC (located in New York City) using a Teletype terminal connected via to New York over special telephone lines. ![]() In 1940, Stibitz demonstrated the CNC at an American Mathematical Society conference held at Dartmouth College. In 1939, Bell Telephone Laboratories completes this calculator, designed by scientist George Stibitz. The Complex Number Calculator(CNC) is completed.Walt Disney Pictures ordered eight of the 200B model to test recording equipment and speaker systems for the 12 specially equipped theatres that showed the movie “Fantasia” in 1940. Their first product, the HP 200A Audio Oscillator, rapidly became a popular piece of test equipment for engineers. ![]() That same year in Germany, engineer Konrad Zuse built his Z2 computer, also using telephone company relays.ĭavid Packard and Bill Hewlett found their company in a Palo Alto, California garage. Bell Laboratories scientist George Stibitz uses relays for a demonstration adderĬalled the “Model K” Adder because he built it on his “Kitchen” table, this simple demonstration circuit provides proof of concept for applying Boolean logic to the design of computers, resulting in construction of the relay-based Model I Complex Calculator in 1939.
