One of my favorite hikes up the california hills was with a friend who worked for Infocom back in the day... it was much later during the DotCom boom and an acquaintance went hiking with us who turned out to have been cracking (and distributing through BBS) my friends games. They had a long conversation on various forms of copy protection and how they were broken... but the great thing was that he still had copies/floppys that worked whereas my friend's copy protected versions no longer read properly!
So my friend was able to get a copy of the game he had written long ago to run again :-) A very happy ending.
