BIOS image for a Philco 10B device whose board is marked 71R-B11E14-T820, supplied as a small RAR archive of a BIN file. Write it with an SPI programmer to recover a unit that will not boot after firmware corruption. The archive is about 618 KB, so confirm the extracted image size matches the flash chip capacity before writing. Back up the existing chip first, and check that the board number printed on the PCB is the same. A schematic for the same board is also catalogued.
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 @biosarchive. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
