   I have fond memories of frustration playing these adventure games.  I remember   
   peeking at the binary to find clues one time, and being confused by finding a   
   bunch of text that didn't seem like it should be in the game.  (Apparently   
   some bits of the data    
   file ended up in the padding areas.)   
      
   I looked around on the web and discovered a bunch of tools and scattered   
   documentation, but most of it was based on a TRS-80 BASIC source listing of   
   Pirate's Adventure published in Byte magazine, or derived by examining how the   
   data files were used in    
   games, rather than disassembling the interpreter.   
      
   I figured I'd fill in a few gaps by disassembling the Apple II version.  The   
   code itself is sort of interesting, making minimal use of zero page, and   
   making heavy use of the stack and inline data to manipulate 16-bit values.
