Setasi PEP70/HC43/HC45 cabling

Does anyone here know anything about the Setasi PEP70 memory system for the PDP-11/70? I posted the question below to the PDP-11 list, and got no reply. :-( Eric Can anyone describe the correct cabling between the PEP70, HC43, and HC45 cards (Setasi's memory and cache-replacement cards for the PDP-11/70)? There are four connectors on the PEP70, and two each on the HC43 and HC45. It appears that the topmost PEP70 connector should be cabled to the second from the top on the HC45, and the second PEP70 to the topmost on the HC45. But I have no idea how the two cables between the PEP70 and HC43 should be wired. There would seem to be only two possibilities, but I am loathe to risk damaging anything by using trial and error. Thanks! Eric
