An M930 terminator in the far left slot in A/B, where you have the RL11
(M7762). I don't remember if the G7273 is a unibus or q-bus grant card. I
always use the G727 , I think, the little 2 inch by 2 inch or so.
Try front panel funstions with the RL11 out. You'll probably have to move
it to slot 3.
There is a trick to using a M9301 or m9312 in an 11/40, but I don't
remember it now. It's been a while since since I've played with an 11/40.

Paul,
What terminator card exactly? As I had written originally, the system was
functional before I added the core planes. I was thinking that I needed a
terminator now that I have more than just the cpu plus four slot plane, but
I did not have the space for it along with all of the cards I already have
installed.

(I removed the grant cards from the core planes per Tony's suggestion.)
