I'm noticing something on my PDP-11/84 that I can't explain. I've
"repaired" the broken power-supply by partially replacing it
(http://flic.kr/p/cKTBn7). The 11/84 runs fine now, except that it
won't boot if I put the Unibus terminator (M9302) in. Without the
terminator, it works fine, and I can access controllers on the Unibus.
According to the manual, however, an M9302 was part of the basic
package. I'm seeing this behavior with two different M9302 modules, as
well as with two different Unibus adapters. Any explanation welcome...
