(I removed the grant cards from the core planes
per Tony's suggestion.)
You don't have a terminator in the last slot of the bus. There should be a
M930/M9301/M9312 installed there, not a RL11. It is possible to put the
M9312 / M9301 there if you install the five jumpers (In my 11/10 there is a
M9301-YF installed in a regular Unibus slot). With jumpers in the
M9301/M9312 will terminate the BGx and NPG signals as well. Without jumpers
these signals will be unterminated which is not good.
Be careful to not put it into a MUD slot with the jumpers in, though.
It is not clear to me if the DL11-W repsonds correctly when you try to
address it or just doesn't output anything.
Check grant continuity from last slot to the M981. But just to output a
character on the console BG/NPG continuity wouldn't matter. Booting from
the RL11 will not work unless the NPG chain (and BG chains are OK).
I actually think that the reason for the RL11 not working is that the grant
signals don't have a pull up anywhere in your config.
