According on this:
http://www.sierraplanet.com/kingsquest4/walkthru.html Note About Special Codes: In some early versions of this game, you may get a special code at the end of the game. If you are curious as to what this code is for, there was a contest that Sierra had over 10 years ago (so obviously it is over by now). On many of the original game boxes, there was a sticker that said, "The Great Master Adventure Contest -- Win a Trip to England or one of 2000 other prizes (see details inside)." Whoever was the first to finish the game and send in that special code found only at the end of the game won the trip (it was a couple from New York). Three runners-up got a new Tandy computer, and a 1000 others got either free software or a T-shirt.
