Probably the rarest computer in my collection is a Japanese version of
the Altair that was given to my by the owner of the company when I was
over in Japan. I liked it so much that I had it mostly assembled except
for soldering by the time I got off the plane :). Other rare stuff would
probably include an 8" drive Polymorphic computer.
