Each pulse input to lip-lop advances counter one position. Single-transistor amplifiers A1-A0 drive glow indicator tube serving as readout. For reset to zero, positive pulse is applied to base of transistor in zero amplifier, to turn its transistor on and turn all other amplifier transistors off.-R.W.
