Sheesh.... I seem to remember wire-wrapping an 8088 processor board to
plug into a S-100 backplane back in the early 80's. Time flies when you
are having fun :-)

 

Regarding the terminator boards in the end slots: While yes, you could
do that I suppose, you would be using up 2 of our 6 slots. If you needed
to add termination to support a different bus topology configured as
multidrop or multipoint you could just make sure your boards with the
bus receivers had termination provisions on them. That way you get your
termination without wasting slots for a board whose only purpose is to
provide terminations....
