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.

and hard drives?
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.
