 During any service action open the keyboard and check the date                 
 code on the upper right corner.  Keyboards with date codes of                  
 12/31/96 and before should be replaced.

 DETAIL:  The original keyboard signal cable (membrane) could                   
 in some cases crack and loose conductivity in some of its lands.               
 This could result in certain key failures when operating or                    
 during POST. The POST error would be 3XX (X = any number.)                     
                                                                                
 The membrane crack is the result of increased cable flexing                    
 caused by a relocation of the 365X and XD system board keyboard                
 cable connectors. A new more robust keyboard membrane has been                 
 designed to allow for the increased flex and eliminate premature               
 membrane failure.                                                              
                                                                                
 The membrane (cable) is an integral part of the keyboard FRU and               
 all keyboard FRU stock has been purged of the affected date                    
 codes.
