Schematic set for the FIC AT11 motherboard, revision R0.2, packed as a RAR archive of about 1.29 MB. FIC, First International Computer, designed boards for several brands, and its codes rather than retail model names identify the drawings. A technician opens the extracted PDF to follow power rails from the adapter input through the regulators, find test points and check where a short may sit. Revision differences can change component placement and values, so confirm R0.2 on the board silkscreen before relying on it.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @IT_SERVICE_WORLD. Enginerys does not host this file.
