Small 124 KB PDF schematic covering the audio and USB daughterboard used with Sony mainboard MBX-165, platform code MS90. Rather than the main logic board, it documents the secondary board that carries audio jacks, codec-related circuitry and USB ports, along with its connector to the motherboard. It helps when a jack or port is dead, letting you trace power to the ports, follow data lines and check fuses or filters. Pair it with the main MBX-165 schematic and confirm the daughterboard markings match before testing.
