RAR archive of roughly 3.3 MB for the Sony MBX-216 motherboard, which according to the name was made by Quanta under project code GD3. The exact contents are not listed, but archives like this typically hold a schematic PDF and sometimes a boardview file, so extract it with a tool such as WinRAR or 7-Zip and inspect what is inside. Such documentation lets you follow power rails, locate test points and components, and diagnose shorts. Check that both MBX-216 and GD3 markings appear on your board before using it.
