     Hi everybody,
     
     
     Does anybody know if it will be possible to keep the same SCSI Ultra2 
     controller to migrate to SCSI Ultra3 in futur ? keeping also the same 
     attached SCSI cable and terminator ?
     
     I mean; will it be possible to keep the same SCSI controller pinout ? 
     (same external signals, external clock ...) ?
      
     Will it be possible to keep the same Printed Circuit Board lay out 
     around the SCSI controller ? (i.e, same trace impedance, same trace 
     length, same embedded terminator....etc) ?
     
     
     Thanks,
     Jean-Luc PRAT
