The main target was to improve the sharing of programs over GM-NAA I/O. SHARE Operating System provided new methods to manage buffers and input/output devices, and, like GM-NAA I/O, allowed execution of programs written in assembly language. Initially, it worked on IBM 709 computer and its transistorized compatible successor the IBM 7090. A series of articles describing innovations in the system appears in the April, 1959, Journal of
