You don't need three-phase for the equipment you got - if you look at
the DEC power controllers, they just split out the three phase into
three 120VAC circuits which power the individual boxes. Especially
as you have MOS instead of core memory, 30 Amps will be plenty for a CPU,
memory, and a couple of Fuji Eagles.
Some big Massbus disks (and their Memorex and CDC mechanical equivalents)
do need three-phase for the drive motor, but I didn't see these in your
list.

Assuming you have the DEC MK11 memory boxes, yes this is true. There
are also third-party memory boards available for 11/70's; my favorite
are the board sets that pop into the 11/70's backplane and give you
4 Megs of cache memory, so there's no need for memory boxes!
