The
DL11 can do both EIA and current loop. The interlock effectively
tells it which of those you want enabled. The "proper" cables have the
appropriate interlock connected depending on what it connects to at
the other end.
Powering on the 11/34a gives me the same... nothing at
all, but as I
suspect the 11/34a is halting somewhere, this is probably quite
reasonable.
You could try shortening the Unibus by pulling the M9202 and putting
the M9203 in slot 9 of the first backplane. Is the M9203 set up for
the ASCII console emulator?
