I can't say for a TU77, but the TU78 is 220V.
The RM07 also was 3-phase, I think all the smaller VAX
780
disks were single-phase. The RM07 was a total monstrosity
from Burroughs, I hope you don't have one of those. We went through
a lot of pain as one of the early adopters of that, but in the
end it was a high performance drive and fairly reliable.
I don't remember the RM07. I remember the RM05 (CDC 9766)
and the RP07, which I _thought_ was a 100% DEC design (that
resembled a white washing machine with no access panels), but
I could be wrong about that.
