The later PDP-11 processor handbooks have a decent cross-reference saying what features and quirks are in each processor from the 11/20 through the J11, going into some of corner cases about how various unusual addressing mode combinations/instructions/traps are implemented in each. Also about registers-accessed-as-memory. A few obvious typos.
Further discussion of more esoteric corner cases is probably best documented in the SIMH sources and past discussions here. The micronotes go into even more detail about various combinations of Q-bus processors and Q-bus backplanes. There's a very concise table in http://simh.trailing-edge.com/pdf/pdp11_doc.pdf but doesn't really get into the corner cases: type bus mem MMU? Umap? EIS? FIS? FPP?
