For an 11/34A can one test for DC LO / AC LO? If so and you don't get the
correct reading that's a show stopper right there. Remove all but the
essential cards, terminate the UNIBUS to the shortest poss. size and least
RAM. I no longer have an 11/34A but there are a lot of similarities to the
11/40. Many cards interchangable.
