CM/2? Where!? The one at the Mountain View Computer History Museum? I only 
know of that CM2 in the wild, along with the Frostberg CM-5 at the NSA 
museum up the road in Maryland.

A Cray and a Thinking Machines were my two "grails." I managed to get one, 
and the sheer weight let it be the final big machine grail :-) When I saw 
the CM-5 at the NSA Cryptographic Museum I was floored to find out it was 
some 9' high and is likely to cause difficully going into a truck. Not to 
mention through a normal door!
