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

I've gotten rid of a lot of wierd stuff in the past.

BUt toiday, I still have some QBUS M68K boards.  And I still have Terak boards (should
qualify as rare I imagine) no Terak boxes but they work OK in any QBUS backplane.

I'm sure if I thought about it there is more.

Here is what comes to mind, it may not qualify as a computer. A
Westinghouse Numa-Logic PC700. It is an early PLC. uses a Sinetics 8X300
bit slice. Unfortunately Westinghouse only started to invest in PLCs about
the time the they merged with CBS and in a few years
all of Westinghouse became history.

BTW Looking for parts, manuals, software, the "lug-able" CRT based
programmer, IDE PC interface etc. etc.

Also will get my Allen Bradly PLC with core memory running someday.
