I've been meaning to ask about this topic for a while. We also know that when programmers have extra space in their roms they sometimes used it to write messages and inside jokes amongst themselves. Sometimes it's just their names, but other times it can be random things. So what is the most interesting thing you have ever found?
A prototype I just sold (The released version has the same message as well) has the introductory paragraph from the Hunt for Red October:
IN NOVEMBER OF 1984, SHORTLY BEFORE GORBECHOV CAME TO POWER, A TYPHOON-CLASS SOVIET SUB SURFACED JUST SOUTH OF THE GRAND BANKS. IT THEN SANK INTO DEEP WATER, APPARENTLY SUFFERING A RADIATION PROBLEM. UNCONFIRMED REPORTS INDICATED SOME OF THE CREW WERE RESCUED. BUT ACCORDINDING TO REPEATED STATEMENTS BY BOTH SOVIET AND AMERICAN GOVERNMENTS....NOTHING OF WHAT YOU ARE ABOUT TO SEE... EVER HAPPENED
