A magazine loader for firearm magazines has a projecting side button coupled to a follower. A developing apparatus attaches a developer to the electrostatic image and develop the electrostatic image as a developer image when applied with a development voltage. Upon encountering a condition which causes the processor to enter scout mode, the system performs a checkpoint and commences execution of instructions in scout mode, wherein the instructions are speculatively executed to prefetch future memory operations, but wherein results are not committed to the architectural state of a processor. A switch matrix selects one of the inductive elements in response to a selection signal in a first mode of operation, and couples together a group of inductive elements to form an antenna in a second mode of operation.
