   Seems I remember reading somewhere that ROM's downloaded for emulators have a   
   header that has to be removed before they can be used to burn ROM's for real   
   machines.  Maybe someone who knows more about that particular subject than I   
   do will jump in with more info.   
      
   As for the other symptoms you mention, there is an excellent 1541   
   troubleshooting guide on Ray Carlsen's website:
