wouldn't you need three phase power and/or 220 volt service for most
'real' mainframes? (I have three phase outputs on my Homelite Gasoline
generator)

Wasn't that popular to install in the 1970s?
While I have no Al wiring in my 90-year-old house, I do have
knob-and-tube, which is why I ran two new 15A circuits to the back
bedroom for the computers.

Many years ago (30+), my grandmothers house was wired by running
cloth covered wires on insulators (like you see used for electric
fences) inside the house. (not inside the walls) One wire on each side
of the insulator. (No 3rd ground wire either)
Want to try hooking up a mainframe using that type of wiring?
