Impressive 220 wiring on this IBM
mainframe. See last photo of sequence.

Thanks for the help (to you and everyone else who chimed in!) -- I wired
it up and plugged it in and it came to life quite nicely! All self-tests
pass as evidenced by the below photo:

Looks like I'll invest in a 240V outlet or two. Can't wait to get it to
do something useful (for some definition of 'useful'); I'm in the process
of getting the software tapes archived (thanks to the help of a local QIC
expert) but once that's done...
Thanks again,

OK: Confirmed two things: There's 240V
between the two HOT terminals
at the outlet, and the ground appears to be grounded (I get continuity
between the ground on the nearby 120V outlet (which I know is properly
grounded) and the neutral terminal of the 240V outlet.)
So it looks like I should be good to go here. One last question -- does
it matter which hot wire goes to which terminal in this case?
Nope.
