Once I saw the MG of a CDC Cyber 960 starting. It needed about one
minute to get up to speed. It sucked 400 V @ 120 A three phsase during
startup. Comment of the operator: "I am glad those NH-fuses are so slow.
We have only a 80 A feed. So starting the machine overloads the 80 A
fuses quite a bit."

The VAX6000 uses three phase to generate a 300 V (?) DC main supply. But
it is possible to convert it to single pahse.
