I've never powered up anything bigger than a quad pentium-pro server on
the 'knob and tube' (what you described) wiring in my house.  I do aim
to sometime not to far off start messing with the SparcServer 1000.  But

'real' mainframes?  (I have three phase outputs on my Homelite Gasoline
generator)
