   i don't know what lowlevel format SCSI used... my understanding is that SCSI   
   is simple the connection and instruction set used to talk to the drive(s)...

   yep... there were many... everyone was trying to lock folks into their   
   solution... kind of like the stupid mess today with the so-called smartphones   
   and having an app for everything... you'd think they would have learned better   
   back then or that they would learn from history and not repeat it in another   
   form...
