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

[Douglas Taylor]

I have a certificate that my father was given in 1957 for training on a 
Honeywell Datamatic 1000 computer.

Here is a summary of this 'advance' in computer technology from the ACM:

The DATAmatic 1000 (D-1000) is a high-capacity electronic 
data-processing system designed specifically for application to the 
increasingly complex problems and procedures of present-day business. 
The system incorporates significant new systems techniques, as well as 
several basically new component developments. One of the outstanding 
features of the D-1000 is its ability to feed information from magnetic 
tape into the central processor at a sustained rate of 60,000 
decimal-digits per second, and to deliver data after processing back to 
magnetic tape at this same rate. The operational speed of the central 
processor maintains full compatibility with the high speed of 
information transfer. Consequently, the difficulties caused by programs 
which are either tape limited or processing-time limited do not arise in 
the majority of commercial applications of this system.
