The fact that the board have four edge connectors and not six totally
excludes PDP-11. I can't tell for sure, but this auction may
be for PDP8 core board.

And, in fact, a number of PDP-11 peripheral boards had
only 4 connectors.
CPU boards and memory did usually have 6.
There were definitely quad height boards, but I don't think I ever saw a
PDP-11 board that was hex height with only four edge connectors. But I'm
sure you will point me to one now. :-)
