A non‐general‐purpose operating system
N. Bernstein, B. Knobe · Software Practice and Experience · 1977
Abstract A time‐sharing system was developed in order to improve a minicomputer's utilization. Because the facilities provided by the system are not identical to those of a general purpose time‐sharing system, additional advantages accrue: The system is implement able on a small machine. The implementation effort is small. A certain class of programs can now be implemented more easily than would be possible under a general purpose time‐sharing system.
