It is just a bus. The internal drive cable is just a lenght

I'll keep an eye out for other controllers, but I think I will order
an extender and attempt to debug the one I have.

Well, not important.
Assuming I eventually get the controller working, I started looking at

And you definitely look like you got a stuck bit in there.
All of the errors show expected and received data, and in all cases bit
13 is on while it shouldn't be.

18 bits would be 774400. But 22 bits would be 17774400. And 16 bits
would be 174400.

Well, I'm sure there's a DEC diagnostic for the DLV11-J, but I have no idea
what it is.

Yes (if the question is 'for input'). What it puts out on the bus I haven't
checked, definitely BBS7 plus the low 13 bits (0-12), dunno about BDAL13-21.

Thanks John, I think the insanity is my own! After changing those
switches I accidentally put the M8014 above the M8013. I've swapped
them and now get slightly different results:
One note, it now takes a while for it to start printing anything,
which I think might mean it's running some of the fir

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

I did just try moving the RLV11 boards below everything else (except
the BDV11), with the same results as before.

No magic smoke so far!
I think you had written something a while back that would test that
interrupt. Was that correct, or is there another diagnostic I can use
to test that?
The 17440 wasn't a typo, it's just my misunderstanding of how the
addressing works. I'll read the actual location later to

try again.
