Duplicate firmware dump named 6400I3, 8.00 MB in .bin format, with the I3 suffix left unexplained and no revision stated. A second copy is handy for confirming that a read is clean: matching files suggest a reliable dump. Open it in programmer software and flash it to a 64 Mbit SPI chip in-circuit or desoldered. Save the board's original contents beforehand, because they hold unit-specific data, and ensure the hardware matches the model named in the file.
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 @biosfilebins. Enginerys does not host this file.
