for common 120V NEMA-15/20 circuits (common household like stuff), the
208/3ph would allow 120V, 240V and the 208/3ph. The latter was quite
common for the early/mid era minis.

requirements, please try to arrive Friday night for electrical
testing and set up. All the talk and prep in the world will not
*prove* you have what you need until you test your space with your
load in this environment. It will be too late Saturday morning for
all that. If you can't, you can't, but try.
It would be ideal if we had an electrician around who can stop by
(even a paid one) Friday night for this purpose just to be sure
everything is OK. Last year we had no special power requirements as
everything except Dave's systems were small. With all 20+ or so
exhibits in just the one room including larger ones - I'd rather be
pleasantly surprised that there are no problems rather than violently
surprised when there are.
...and this means we MARCH people running the show will have to work
something out. I expect Evan has already done some of this leg
work. Send me your specs and I will coordinate with Evan and the
InfoAge electrician(s). If you don't send specs then don't get upset
if you're not allowed to turn everything on at the expense of the
others who have given us enough time to prepare.

will be bringing a UPS myself. 550va 330Watts. I will be plugging in four
C64s with Heavy Duty power supplies, four 1702 monitors, four 1541 drives,
one PC laptop or desktop, possibly a VGA monitor. I'm not sure how to
calculate the power for all this. Does that help ?
