  42.  
  43.             UNPROTECT PATCH FOR SIDEKICK VERSION 1.5
  44.  
  45.                                BY
  46.                           STEVE SCHAUER
  47.  
  48.  
  49. Use the following steps to unprotect Sidekick Version 1.5.  After
  50. modifying SK.COM the program will no longer look for the key disk
  51. in Drive A: and you can run the program off your hard disk alone.
  52.  
  53.  
  54. You should modify a COPY of SK.COM with DEBUG by entering the
  55. following commands:
  56.  
  57. you enter:              DEBUG SK.COM    <CARRIAGE RETURN>
  58.                         A 089E          <CARRIAGE RETURN>
  59.  
  60. DEBUG responds with:    XXXX:089E       <XXXX CAN BE ANY NUMBER>
  61. you enter:              NOP             <CARRIAGE RETURN>
  62.  
  63. DEBUG responds with:    XXXX:089F
  64. you enter:              NOP             <CARRIAGE RETURN>
  65.  
  66. DEBUG responds with:    XXXX:08A0
  67. you enter:                              <CARRIAGE RETURN>
  68.                         A 08AD          <CARRIAGE RETURN>
  69.  
  70. DEBUG responds with:    XXXX:08AD
  71. you enter:              OR <TAB> AL,01  <CARRIAGE RETURN>
  72.  
  73. DEBUG responds with:    XXXX:08AF
  74. you enter:                              <CARRIAGE RETURN>
  75.                         W               <CARRIAGE RETURN>
  76.                         Q               <CARRIAGE RETURN>
  77.  
  78. That's it!  The modified version will now run as an unprotected copy
  79. of Sidekick.
  80.  
  81.  
  82. REMINDER:  The instructions above enclosed in <BRACKETS> are not to
  83.            be typed in; when it says <CARRIAGE RETURN> or <TAB>,
  84.            you should press that key at that point.  <You knew that,
  85.            didn't you?>
  86.  
  87.  
  88.  
  89. SECOND REMINDER:   Fate being what it is, you did modify a copy of
  90.                    Sidekick and not the original, didn't you?
  91.
