Perseus: A Retrospective on a Portable Operating System

The authors describe the operating system Perseus, developed as part of a study into the issues of computer communications and their impact on operating system and programming language design. Perseus was designed to be portable by virtue of its kernel-based structure and its implementation in Pascal. In particular, machine-dependent code is limited to the kernel and most operating systems functions are provided by server processes, running in user mode. Perseus was designed to evolve into a distributed operating system by virtue of its interprocess communication facilities, based on message-passing. This paper presents an overview of the system and gives an assessment of how far it satisfied its original goals. Specifically, the authors evaluate its interprocess communication facilities and kernel-based structure, and discuss its portability.
