   The difference between the 4D keyboard and the Model 4 keyboard is that the 4D   
   includes an extra backspace key. If you have a broken 4D or a known good   
   keyboard, please let me    
   know!   
      
   actually the backspace key was a 4D keyboard but was also the replacement   
   model 4 keyboard for the units that has the curse "wafer" keys and R/S   
   replaced them with the 4D keyboard, so you may find a "4D" keyboard on a model   
   4.
