    ABSTRACT:: A simulation technique has been developed for the reliability
               evaluation of arbitrarily defined computer systems. The main
               simulation program is written in FORTRAN IV, and requires no
               changes to simulate many different systems. The user defines
               a model for a particular system by supplying a set of short
               FORTRAN subroutines, and a specially formatted block of
               numerical parameters. The subroutines specify the functional
               behavior of various subsystems comprising the model, while
               the numerical parameters describe how the subsystems are
               interconnected, their time delays what faults occur in each
               one, etc. The main simulation program uses this model to
               perform a Monte-Carlo type evaluation of the systems'
               reliability.

               This report supplements a basic description of the technique
               by supplying all the details necessary for writing
               subroutines, specifying numerical parameters, and using the
               main simulation program. The simulation is event-driven, and
               automatically generates pseudo-random faults and time delays
               according to parameters given by the user. Some problems
               typical of event simulators, such as ambiguities arising from
               random time-delay generation, can be solved by taking
               advantage of special facilities built into the simulation
               package. A complete source listing of the main program is
               included for reference.
