Abstract: The system is responsive to a signal from a weight computer to selectively move levers on a lever type postage metering machine to postage selecting positions corresponding to computed postage. The system includes a plurality of actuating members with connecting members for embracing the tabs on the ends of the postage selecting or setting levers of the metering machine for moving the levers to the selected positions. The connecting members follow the natural motion of the tabs on the postage selecting levers. The operating members are moved to their selective positions by alternating rotating discs controlled by an alternately driven motor, which is driven in response to a signal from the weight computer with a comparator circuit for comparing and selecting the respective positions of the discs.
