`ABSTRACT
`
`A computer system for multi-processing purposes. The
`computer system has a console comprising a first coupling
`site and a second coupling site. Each coupling site comprises
`a connector. The console is an enclosure that is capable of
`housing each coupling site. The system also has a plurality
`of computer modules, where each of the computer modules
`is coupled to a connector. Each of the computer modules has
`a processing unit, a main memory coupled to the processing
`unit, a graphics controller coupled to the processing unit,
`and a mass storage device coupled to the processing unit.
`Each of the computer modules is substantially similar in
`design to each other to provide independent processing of
`each of the computer modules in the computer system.
