Just out of curiosity, how much current is needed for an
11/780?
Depending on options, the CPU cabinet would draw about
10-12 A per line, 3-Phase 208 V. And, that is on the
upper end of the range. Starting surge would be a lot
more, of course.

How much power is used for memory
and hard drives?
memory power was provided by the row of power supplies below
the CPU cards as seen in the pics.
Memory power on the /780 was pretty insignificant, as that
system didn't have large memories.
The original /780 had 256 KB memory cards, I think the one
in the current sale has the newer memory system with 1 MB/card.
Hard drive power was QUITE substantial, the bigger drives
had pretty big 3 phase motors to spin the big disk packs/HDA's.
