So I saw yesterday cray released a new super computer (I know, I am a sucker for cray. it just fascinates me along with super computers and mainframes in general) but it strikes me with an interesting question.

Has anyone built a super computer in the old ages using Motorola 680x0 chips?

I know IBM built a few (I.E. Watson) using PowerPC chips, but has anyone built a super computer/mainframe using the old Motorola 68k chips?

If anyone has, can I get a reference?

I think the 68040 was SMP aware, but I could be incorrect about this. I think it would be cool if someone figured out how to do that.
