Well I just figured out something important...The

the switch numbers referenced on the next page. I'm not sure if that's
just the way it is, or maybe someone replaced my switches at some
point. After changing my switches I can now read 774400, which gives
me 144201.
The VRLAC0 diagnostic now goes further, but it thinks something is
wrong. Now of course I have no idea what it thinks is wrong here!

Ah! Progress. That explains your initial problems then.
Well, now that we can communicate with the controller, let's move on. Do
you have any drives connected? Do you have the terminator for the drives
in place? Is all the cards in the Q-bus continuous without any gaps in
the bus?

Okay, I think I need to be looking at 774400,
which doesn't return
anything. Also, the PDP11GUI has a handy RL11 dialog to show all of
the registers, which I think shows the same thing... It's not there!
I've double checked my switch settings, and tested the switches
themselves for continuity just to make sure they weren't bad (which
has happened to me before). Beyond something physically wrong with the
boards, is there anything else I might check?

For 18 bit addresses, I assume I would look at
74400 instead? I get
177777 there.
I did just try moving the RLV11 boards below everything else (except
the BDV11), with the same results as before.

I wonder if it really uses 18 bit addresses in the console.
