I got an old computer from a press which needs a new programmable battery since it gives an error message about CMOS. I need to replace the old one but must also transfer its program.
This is an equivalent of the DS12887. If the internal battery is dead you lost the data that was in the NVRAM. You need to find a copy of the binary file.

You are lucky no critical data like calibrations was lost with the dead battery.
if that was the case we would need a donor board to read the chip that was still operational. but how would we do that? I think we did not clarify this part :)
