- I need help installing my BA11k expansion box to my pdp11/34..
- It wont boot up correctly when I hook the unibus connection up to it. It
- will send nothing to the terminal and nothing shows up on the display of
- the CPU. The processor however is running according to an LED on the CPU box.
-
- I took all the boards out of it that dont look like memory and tried
- again with no luck... I get the sdame result...
