Compressed package labelled FIC VME40, about 1.01 MB, with no revision or contents given in the name. FIC, First International Computer, was a Taiwanese ODM that designed boards for many brands, and VME40 is its board code. Archives like this in repair libraries generally contain a schematic. Open it with 7-Zip or WinRAR, then use the pages to trace power, signals and test points. As the revision is unknown, compare the title block of the document against markings on the board.
