%X The first Brazilian microsatellite will be launched at the
   middle of 1998. The on\-board computer, named Trisputer,
   will play a major part in the mission, since it will perform
   essential on\-board functions, such, as guidance, control of
   the on\-board instrumentation, telemetry/telecommand, and
   control of some on\-board scientific experiments. The
   Trisputer is a fault\-tolerant multiprocessor computer with
   a high reliability, when compared to such systems as TMR,
   and Duplex. This paper describes the conception and
   implementation of the hardware of this computer, as well as
   it shows its reliability model.
