I have a CM-200A; the smallest 'classic' CM
machine. I've started a
project, with some ex-TMC people (notably the designer of the
beautiful chassis the CM machines came in, Tamiko Thiel) to get my
machine operational next year, for the 30th anniversary of the launch
of the CM.
Kudos! You're the first private collector I've heard that owns a CM!
A SGI fanboy friend I think almost scored a CM-2 once but it didn't
happen.
One CM5 I saw in real life was small and not impressive looking, was a bit
let down. Then when I saw the 2nd CM-5 cabinet in real life it was so huge
that I realized had I ever found one it wouldn't fit in any normal garage
or room.
