The first operating system for the EDVAC

The paper describes the first operating system that was designed for the first internally programmed electronic digital computer: the EDVAC. This operating system was developed during 1952 and was implemented early in 1953. Devised for one of the earliest electronic digital computers, its capacities were modest compared to later standards, yet some of its features are recognizable in later operating systems. It was planned carefully, and it was comprehensive and useful in the context of its time.
