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

[Gary Oliver]

My most obscure (though far from rare, as no one has ever heard of them) 
is a Gnat System 10:

Z-80 (4MHz if I recall on mine) with SCSI (Perhaps SASI at the time) 
interface, lots of parallel and
serial connectors on back.  An early all-in-one sold by a computer 
making pretty decent
process control z-80 machines.  We connected to a load of them back in 
the late 70s on
some automation projects.  Their "rack mount" computers were pretty damn 
solid and
my System 10 still runs.  It's a CP/M machine and  I used it as my main 
'terminal' to BBSs
and such for quite a while.

Also have an IMSAI, a Sol-20 (rescued from dumpster.)

Oldest tech is probably a "Typotron Display" crt from Sage computer 
system (a 4 inch
storage tube about 3.5 feet long with for displaying textual context.)  
Removed by
me from a Sage console in about 1972 or so.  Wish I had kept the whole 
console :-(
but it weighed about 800 pounds (guestimation from difficulty in loading 
and unloading
from a flatbed.)  A friend got the *big* 14 inch main tube...
