Archive tied to the W7650 system and the FIC MR056B board, revision 0.1, about 1.32 MB as a RAR file. W7650 appears to be the retail model while MR056B is the First International Computer board code used on the PCB itself. The name does not list what is inside, but such packages typically hold schematics for tracing power sequencing, checking signals and locating parts. Verify that the MR056B marking and Rev 0.1 match the board on the bench before relying on the drawings.
