Risc PC
     
         The latest addition to {Acorn}'s {Archimedes}
        family of {personal computer}s.  The Risc PC, released in
        April 1994, allows a second processor, e.g. an {Intel 486} or
        a second {ARM}, to share the {bus}, memory and {peripherals}
        with the main processor.  It also offers significantly
        increased speed with an {ARM610} {RISC} processor and full
        24-bit colour graphics support.
