I had a look at my /45 (a later KB11-D - although I think the backplanes for
the -A and -D are identical), and it seems to have heavy red wires attached
to the upper row of Mate-n-Lok's that look just like those on Josh's. I'd
really want to take pictures of mine (I don't want to take the backplane out
- too much work - but I can get decent images with it in, I think) so I
can compare them directly, though, not depend on visual memory.

PS: I wonder how many people here have -11/45's? ISTR one other, but they aren't
common.
