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

I have Nicolet 1080. It is a 20 bit computer and has 12Kx20 core memory. To my knowledge, there are only 5 of these remaining in existence. Only 375 were said to have been made. Mine is mostly working but the last time I ran it, it had disk problems. I need to debug it.
