Even as we introduced the models that completed the "First Generation" of Analog Devices panel meters, the second generation was in the final stages of engineering. The first generation, as users know, consisted of both +5V logic-powered units and ac line-powered devices, using TTL small-scale integrated circuits for logic, linear IC's and discrete components for analog circuitry, and a "mixed bag" of displays.
