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. Bill
