      Make sure all of the original code from $078E - $07FF is left
      undisturbed.
      
      Now write all the code to the work copy by inserting your work
      copy into the drive and entering:

         ]:0006 12 04 12 07 12 0A 12 0C
         ]:000E 12 0D
         ]:0000 90 90 90 90 90

      There is the third level protection present on this title. To
      remove it, enter the following:

         ]:0006 18 0D
         ]:0000 80
         ]:0362 6B
         ]:036E 45
         ]:0000 90

      That's all there is to it! Enjoy your backup copy.

      
      < < < MINDSCAPE: PAPERBOY > > >
      
      The entire protection removal process will take place in the
      drive. We are going to let the protected code on track 20 load into
      the drive and then re-write it to some empty directory sectors. We
      will then modify the code that reads track 20 so that it instead
      loads our newly-filled sectors.
      
      Prepare a work copy of Paperboy using the MAX Copier on your
      utility disk, and then load the $1000 monitor. Insert your original
      Paperboy, initialize the drive (@I) and enter the drive-mon. We'll
      be using the 1541/71's job queue to do a lot of the work for us.
      
      Read T/S $12/$0D into buffer $0700 by entering:

         :000E 12 0D
         :0004 80
