I can't provide a picture... they are at home. They are, IIRC,
under-driven 28V bulbs with drawn copper wires coming through the
envelope - not the sturdy pin type used in later machines like
the -8/i, -8/L and -8/e.

Not usually... the only openings are to tunnels. The "main entrance"
is at least 75 feet from the actual dome. When you go "inside",
there's a large tranverse arch you cross first... large enough for
buildings to fit under (Bio-Med to the left, Old Power Plant to the
right).
