I just realized that one of the connectors I did find was one which
appeared to connect over-the-top with two boards. The other one I
found has three connectors, and the spacing between 1 and 2 is
different from that between 2 and 3... I presume it is because 1 and
2 connect to the CPU and FPU in slots 2 and 3, and the third needs
extra space to connect to the Cache in slot 5...

I may just have what I need to get that working...

First step will be to remove everything from the backplane and
vacuum it out...
