It is the MK11 MOS Memory box backplane, not the cpu backplane which
is bigger (and has lots of twisted pair wiring).

Oh, right you are! I don't know where my brain has fled to these days!
It's actually an MJ11 (-11/70 core memory) backplane (I checked the part
number - plus someone pointed out that you can see "MJ11" written somewhere).

The 11/70 backplane is wirewrapped. If that is an 11/70 backp
