This link (that Motoko gave) is probably the best surviving list and discussion of the game's inventory of unconditional weapons.
As with any other legend, things tend to grow and become more and more disconnected from reality as the game of telephone stretches over the decades. I hope that game continues to stretch over many decades. At the same, though, it's nice to have a chance like this to dust off that thread and shine a little bit of light on reality.
Thanks, Motoko, for starting this thread. Hopefully it helps more people understand a little bit more about our little universe.
