1. A computer system for use in an emergency response vehicle, the system comprising:
- a primary processing subsystem having a primary processor, said primary processing subsystem adapted to provide a first graphics output stream;
a video capture subsystem having a video capture processor and non-volatile memory, said video capture subsystem in communication with said primary processing subsystem and adapted to provide a second graphics output stream;
a storage multiplexer connected to said primary processing subsystem and said video capture subsystem;
a non-volatile storage device accessible by said primary processing subsystem and said video capture subsystem through said storage multiplexer;
a display multiplexer subsystem coupled to said primary processing subsystem and said video capture subsystem for receiving at least two graphics output streams and providing a multiplexed graphics output stream;
an enclosure housing said primary processing subsystem, said video capture subsystem, said storage multiplexer, said display multiplexer subsystem, and said non-volatile storage device; and
display means connected to said display multiplexer subsystem for displaying a multiplexed graphics output stream, said display means defining a portion of the exterior surface of said enclosure.
