This means that you not have the terminator in the last slot of the bus,
right? Since your bus is so short it won't probably matter.
I have now beeped my way through all signals of the AB slots of the
11/05-NC backplane. Slots 2-9 has "Standard Unibus Pin Assignments" No MUD
Then I rechecked the M9301 and M9312 schematics. There are no signals used
on those that would conflict with the "Standard Unibus Pin Assignments". I
will also check the boards physically to see if there is a difference in
signals that are used. Then unless someone tell me "it won't work, I have
tried setting a M9301 in a standard unibus slot" I will go ahead and try
it. After all this is how my PDP-11/05-S was configured when it arrived.
