A system for configuring a plurality of programmable devices may include an external memory, a master programmable device, and at least one slave programmable device. The developer may include an ink bearing surface from which ink is transferred and a cleaner for removing ink from the ink bearing surface. The housing includes a support member that has a deflectionretention feature that extends above a plane formed by the circuit board after the board has been assembled to the housing. A compensating unit compensates the feature vector based on the third compensation vector. In one embodiment, an air bridge is produced by depositing one or more circuit components on a substrate, depositing a sacrificial material over at least a portion of the circuit components, depositing a first circuit trace over the sacrificial material, the first circuit trace crossing over the circuit components, and thermally decomposing the sacrificial material.
