[...] sounds like an interesting collection... but an
expensive one
to power up.
All in all, the minis aren't that bad on power. The Novas only draw
a couple hundred watts and usually aren't powered on at the same time.
The pdp11/34a is a hog, though; the month I started working on that one
the power bill went to $75.
I believe the largest amount of computer power running in the
house at once was the time when my wife had both PCs up and I had my
DECstation, VAXstation, and InterAct fired up at the same time. The
LAN took a beating that day.
I assume you've read Soul of the New Machine about
the Data General
push to a 32 bit response to the VAX?
What DG "head" hasn't?
Cheers.

You should try my PDP11/45 system - 8 demountable hard disks, magtape, a
couple of expansion boxes, paper tape, etc. It probably pulls about 4kW in
total.
Fortunately I'm in the UK, where we have 240V mains, and where the
standard mains circuit is a 30A ring main. That's 7.2kW (or thereabouts),
and I have such a circuit just for my computer room. Of course that
doesn't affect the cost of running it, but at least it means I can run up
these larger machines from time to time.

Hrumph! You have not seen a power meter REALLY spin until I hit the
switch on my Vax 11/780! Even the PDP-11/70 in the collection comes
in a poor second to that critter! ( ridiculous huge B^} )
