ABSTRACT:
A postage value determining scale includes a processor which accesses postage data stored in a rate PROM carried on a card. In a basic implementation, the PROM card is mounted to a memory port socket of a circuit board which carries the processor. The processor is programmed for optional postage value related functions such as zip code to destination zone conversions and postage rate determinations for mailing from a remote origination point. The PROM carried on the rate PROM card has insufficient memory space for the optional functions. When a scale capable of providing the optional features is desired, in lieu of connecting the rate PROM card directly to the memory port, a transition board is provided for connecting the main board to a ribbon cable assembly. The ribbon cable is connected, at its opposite end, to a carrier board having a plurality of sockets and a cage for mounting a plurality of memory carrying cards including the rate PROM card. In order to match the conductor polarity between the memory port socket and the carrier board plug, the conductors of the transition board extend through the board to opposite faces of the board at each end.
