Noel, is it possible for you deduce where Unix _should_ be placing these 
  "bad" bits (from file offset octal 4220)?

Maybe a comparison of addresses where the bits should be, with addresses 
where the "bad" copy ends up, could point us at some particular failure 
modes to check in the KT11, CPU, or RK11...
