History of IBM mainframe operating systems

The GM-NAA I/O input/output system of General Motors and North American Aviation was the first operating system for the IBM 704 computer.[1][2]

It was created in 1956 by Robert L. Patrick of General Motors Research and Owen Mock of North American Aviation.[1] 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 (batch processing). It was formed of shared routines to the programs that provided common access to the input/output devices. Some version of the system was used in about forty 704 installations.[1]
