Experience designing the waterloo port user interface
Michael A. Malcolm, Doug Dyment · 1983
The Waterloo Port operating system was produced by the Software Portability Group at the University of Waterloo as part of an ongoing research project. Port runs on a variety of personal workstations, and is used by researchers and by 120 students annually in fourth-year and graduate real-time programming courses. Many of the concepts in Port evolved from our earlier system, Thoth [1,2]. The emphasis on message-passing semantics and an anthropomorphic view of multi-process structuring [3,4] remains a focus of this evolution; integration of the implementation language with the user interface and file system is more evident in Port [5].
