Description

Robert L. Patrick describes the various computer systems he worked on in the early years of computing. His review covers the IBM Card Programmed Calculator through the IBM 701 with the Speedcode interpretive programming system through the IBM 704 with an early FORTRAN compiler. This was followed by the IBM 709 with the SOS operating system, developed jointly SHARE and IBM, and then the IBM 7090 with the IBSYS operating system developed by IBM. Successful features from all of these operating systems were incorporated into the design of System/360 when it was released in the mid-1960s.
