Design and Behavior of TSS/8: a PDP-8 Based Time-Sharing System
Ad van de Goor, C. Gordon Bell, D.A. Witcraft · IEEE Transactions on Computers · 1969
TSS/8 is an existence proof for a small-scale time-sharing system. Design, development, and performance analysis have occurred in quasiparallel. Performance analysis includes two models and two levels of simulation (using SIMULA). The final simulation, an accurate model of the real operating system, predicts the observed behavior.
