Archive for a Y23 board design built for AMD Richland with an A10 APU, labelled MV-QCMC, in a 1.79 MB rar. Richland is AMD's 2013 APU generation, so this relates to an A10-equipped variant of the Y23 family. The contents are not stated, but a file of this size often holds schematic or board documentation used to trace power rails and signal paths. Confirm the board code and APU platform on your unit, as Y23A layouts for other variants are listed separately.
