An elongate spindle member having rigidity and stability against pressure and tensile loads as well as bending and torsional loads is made by winding-up a plurality of mutually interlocking chain links, during axial advancement of the chain links, into a helical winding by a winding guide. This signal informs the cache coherent interconnect to expect an ownership transfer acknowledgement signal from the initiating master upon readwrite transfer completion. A spectrum display may be superimposed as a third dimension on a two-dimensional tuning field with one axis representing the frequency, the second axis representing tuning resolution and the third axis representing the signal level. The microprocessor is responsive to the second detectors to determine if non-paper materials are included in the mailpiece and, if not, determines the volume from the dimensional measurements and estimates the weight as the product of the volume and a density for paper output an appropriate postage amount to the meter and the mailpiece to the printer.
