While only a hundred or so systems were sold, TSS/8* was significant because it es- tablished the notion that multiprogramming applied even to minicomputers. Until recently, TSS/8 was the lowest cost (per system and per user) and highest performance/cost timesharing system. A major side benefit of TSS/8 was the training of the implementors, who went on to implement the RSTS timesharing system for the PDP-11 based on the BASIC language *TSS/8 was designed at Carnegie-Mellon University with graduate student Adrian van de Goor, in reaction to the cost, performance, reliability, and complexity of IBM's TSS/360 (for their Model 67). Although the TSS/360 was not marketed. it eventually worked and contributed some ideas and trained thousands for IBM. At Carnegie-Mellon (CMU), a TSS/8 operated until 1974 when the special swapping disk expired. The cost per user or per job tended to be about! /20 of the TSS/360 system CMU ran. _______________________________________________ Simh mailing list [email protected] http://mailman.trailing-edge.com/mailman/listinfo/simh
