The SHARE Operating System (SOS) is an operating system introduced in 1959 by the
SHARE user group. It is an improvement on the
General Motors GM-NAA I/O operating system, the first operating system for the IBM 704. The main objective was to improve the sharing of programs.
The SHARE Operating System provided new methods to manage
buffer
Buffer may refer to:
Science
* Buffer gas, an inert or nonflammable gas
* Buffer solution, a solution used to prevent changes in pH
* Buffering agent, the weak acid or base in a buffer solution
* Lysis buffer, in cell biology
* Metal ion buffer ...
s and
input/output devices. Like GM-NAA I/O, it allowed execution of programs written in
assembly language
In computer programming, assembly language (or assembler language, or symbolic machine code), often referred to simply as Assembly and commonly abbreviated as ASM or asm, is any low-level programming language with a very strong correspondence b ...
.
SOS initially ran on the
IBM 709 computer and was then ported to its transistorized successor, the
IBM 7090.
A series of articles describing innovations in the system
appears in the April 1959 ''
Journal of the Association for Computing Machinery.''
In 1962,
IBM discontinued support for SOS and announced an entirely new (and incompatible) operating system,
IBM 7090/94 IBSYS.
