Do you get _anything_ on the console terminal of the

I fixed that when I removed the RH11. But now I have the beeping BA.
BTW, what sort of power connector do you have on the
new DD11? Most
systems use a 15 pin connector for power and a 6 pin one for the power
status and line clock signals. Some very early machines used a little PCB
thing that fitted into one of the backplane connectors. And a few early
11/45's used 8-pin mate-n-locks, like the current loop connectors.
It doesn't work. It has normal plugs, but it can't get DC right. It
trips something that resets the PSU.
Just to confim the obvious. You have a unibus cable
from the A&B
connectors on the far left of the CPU backplane to the A&B connectors on
the far right of the DD11, right? And a terminator in the A&B connectors
at the far left of the DD11.
Yes.
