What's the rarest or most unusual computer-related item do you own?

I wasn't even aware of the LCM until this thread.. thanks guys!  Always wanted to go to CHM but it's in California, a long way from here.  LCM is much closer and I like the concept better given that they operate stuff.  I'm thinking eventually my collection will go to a museum somewhere, LCM seems like the kind of place I'd want it to go to.
