Combined archive covering two Compal boards, LA-9981P and LA-9982P, at revision 0.2, compressed into a 1.90 MB RAR. Shared documentation like this usually means both boards are variants of one platform and appear in a single schematic set. Revision 0.2 is an early engineering revision, so values and part placement may differ from production boards marked with a later revision. Compare the number on your PCB, then use the drawings to trace power rails, signals and protection circuits when diagnosing a fault.
