a strictly analog/needle meter, or ID an display in general. I recently read about a "Technos" model, which was supposedly made in Florida by NASA engineers back in 1974. It was a TR type, and had a digital ID display, and was allegedly the first to have such.
Again, "supposedly", since I wasn't TH'ing then and have no personal experience with one, only about 50 of them were sold. They weighed 7lbs, and carried an $850-$900 price tag. A post somewhere mentions that those displays had a habit of failing within a few years.
