Yeah, each CPU was equivelant to a sparcstation-2, plus there
where some FP units, not sure on the details of those.

The CM-1 and CM-2 were much more fine-grained - higher number
of slower processors. (The CM-1 was basicly a prototype. They
made a couple, which turned out to be almost useless for real
world work. The CM-2 fixed those problems, and went over well.)

One weird thing about the Connections Machines is that lisp was
highly optimized for them - it was supposedly the best language
to program the beast in. Arguably, the CMs were "lisp supercomputers"
(a slight exageration, but not by much).

They were designed on Symbolics machines.
