This paper describes the early issues, obstacles, and ultimate achievements of Phase II of the DARPA Advanced Computing Systems project to develop a proofof-concept prototype for a B3 X Window System on a TMach base. The paper defines initial project goals, presents an overview of X, and describes system objectives. The major implications of meeting the B3 trust criteria and the constraints of building the Trusted X prototype on the TMach system (itself a prototype) are described. The paper leads the reader through the process of Trusted X evolution from an initial architecture requiring a large and complex TCB to an architecture based on task polyinstantiation greatly simplifying the TCB<sup>1</sup>
