It was created in 1956 by
Robert L. Patrick of
General Motors Research and
Owen Mock of
North American Aviation.
It was based on a system monitor created in 1955 by programmers of General Motors for its
IBM 701.
The main function of GM-NAA I/O was to automatically execute a new program once the one that was being executed had finished (
