ROM image archive of 3.56 MB, identified only by the numeric prefix 73483 and the word rom, with no brand, model or version given. Such files are typically flash dumps from satellite receivers or similar devices, written back with an SPI or parallel programmer. Since the target is unknown, open the archive and check the image size and internal strings to identify the device. Compare the image size with the flash chip capacity, and always read and save the original chip contents before writing anything new.
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 @tvsoftwareworld. Enginerys does not host this file.
