                                      ____________                                     
          Before KRASS, JERRY SMITH, and GROSS, Administrative Patent Judges.          
          GROSS, Administrative Patent Judge.                                          



                                   DECISION ON APPEAL                                  
               This is a decision on appeal from the examiner's final                  
          rejection of claims 1 through 25.  In the Answer (page 4) the                
          examiner withdrew the rejection of claims 2 through 6, 11 through            
          17, 20, and 22 through 25.  Accordingly, claims 1, 7 through 10,             
          18, 19, and 21 remain before us on appeal.                                   
               Appellant's invention relates to a redundant peripheral                 
          device subsystem in which a controllable switch selectively                  
          isolates two peripheral device busses or joins them into a single            
          peripheral device bus when a fault occurs in the controller                  
          coupled one of the two busses.  Claim 1 is illustrative of the               
          claimed invention, and it reads as follows:
