General Question about UNIBUS backplanes

[Paul Anderson]

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.
