From that last picture, it looks like one of the plugs
is five pronged,
and looks very similar to the 120/208V 30A 3? plug in one of the
pictures about the current 780 auction.
Not too surprising; the /780 and /785 are basically the same machine. (In
fact, one could convert a /780 to a /785 by pulling out the /780 CPU cards
and replacing them with a set of /785 cards; basically the same cards, with
the 74S chips replaced with 74AS.)
