Engineering Response to the Star LSI Workstation Goals Version 2.0 May 1979 The Star LSI Workstation Goals document sets guidelines for the implementation of a low cost workstation (terminal, processor, and peripherals) for the OIS Star product. This document responds to those goals. Version 2.0 represents current thinking concerning the design of the Star LSI Workstation.

Introduction, Conclusions, and Recomendations' The Star LSI Workstation Goals document [reference 1) sets guidelines for the implementation of a low cost workstation (terminal, processor, and peripherals) for the OIS Star product. This document responds to those goals. Between October 1978 and April 1979 a number of studies have been conducted to determine the most appropiate implementation for the workstation. The October study, reference (10), made a broad investigation of possible design approaches. In addition, this study carefully evaluated a synchronous design approach, developed by Butler Lampson (PARC) reference (2), in view of the goals. The recomendation of the October study was to pursue the synchronous approach. During January and
