An attendant sends messages to the Model I relay computer.
The first demonstration of remote computing took place on Sept. 11, 1940.
George Stibitz, of AT&T's Bell Telephone Laboratories, demonstrated his
Complex Number Calculator, the world's first electrical digital computer, to
the American Mathematical Society at a meeting at Dartmouth College in
Hanover, New Hampshire A teletypewriter was installed in a lecture hall at
Dartmouth and connected via a modified teletypewriter line to Stibitz's
electromechanical computer in New York. An attendant at the keyboard entered
equations suggested by meeting attendees. The messages traveled down the
circuit to New York, and the answers were returned to the teletypewriter via
the same route.
What did the "brain
of the Complex Number Calculator consist of?
