PMI memory on an -11/93 (Was: Installing an operating system on an 11/83)

I forget how the -11/84-94 backplane is wired (it's wierd - the QBUS CD slots are bussed together in a group, they're not in pairs like an ordinary Q/CD backplane - but I forget the fine details), but how does the PMI get from the CPU to the KTJ11, then? I know on the same backplane, it supports PMI memory cards with the KDJ11-B. And speaking of the KDJ11-B, I just looked at one, and _it_ doesn't have any lands on the C/D connectors, side 2, either! Probably because the PMI only uses side 1 lands: https://gunkies.org/wiki/Private_Memory_Interconnect#Pinout Given that the KDJ11-E can do master-slave cycles through the KTJ11-B (to read UNIBUS device registers), it has to be able to do master-slave cycles on the PMI. What I don't know is whether, on a 2MB KDJ11-E, it will try and send memory reads for locations > 2MB out the PMI, or whether all reads below the UNIBUS address space (in 22-bit address terms) are sent to the local memory _only_. Someone with a 2MB KDJ11-E should try it... Noel
