In a KS10, the Unibus A in at 1AB is an M9014 paddle card, an M920x bus
jumper or BC11 cable would work as well.  9AB must contain either an M930x
terminator or a cable to the next Unibus backplane.  Most systems don't
have dual Unibi so 8AB should contain an M930x terminator.  In an RH11C
(used with KS10), 3AF is an M7294YA instead of a straight M7294.  The M688s
are optional if there is another device hanging off the same power supply
as the RH11 which drives the power fail lines (on that Unibus).
