AbstractAn electronic weighing scale for determining the postage value of weighed articles. The scale features easily accessible electronics for a postal rate table in stored memory. Because the postal rates on packages change with a fair amount of periodicity, the stored memory electronics containing the postal rates require frequent replacement. This replacement is accomplished easily by means of the invention. The stored memory is on an easily removable chip disposed on an IC board. The IC board is secured to a pull-out draw on a side of the scale housing.
