EARLY OPERATING SYSTEMS
This section lists early operating systems of the 1950s and early1960s
that are primarily of historical interest. Most of these systems were batch
systems or single job monitors for large computers. Early examples of other
categories, such as timesharing, minicomputer, or real-time systems, are
listed with their respective sections.
- Operating system for the Honeywell 800/1800. Early 1960s [Bouvard 1964].
- Atlas I Supervisor
- Supervisor Program for the first computer designed to use an operating
system. Introduced system calls and virtual storage. U. of Manchester,
mid 1960s [Kilburn et al 1961, Howarth et al 1961].
- B1, B2, B3, B4
- Operating Systems for NCR Century series computers. Early 1960s [Datapro
- Basic Executive System
- Memory-based real-time executive for the IBM 1710. Early 1960s [Harrison
et al 1981].
- FORTRAN Monitor system. Operating System developed by North American
Aviation for the IBM 709. Late 1950s [Weizer 1981, Bashe et al 1986].
- GM OS
- A very early operating system developed by General Motors for the IBM
701. Unnamed. About 1955 [Steel 1964].
- Honeywell Executive System. Operating System for the Honeywell 800.

American Aviation for the IBM-704. About 1956. [Steel 1964, Bashe et al

- Semi-Automatic Business Related Environment. The first major transaction
processing system, developed by IBM and American Airlines for the IBM 7090.
Early 1960s [Jarema & Sussenguth 1981].
- Semi-Automatic Ground Environment system. Control Program for IBM AN/FSQ7
to monitor weapons systems. First real-time control system. Late 1950s
[Everett et al 1957].
- Operating System developed by the IBM SHARE Users Group for the 709.
