From same site, interesting info on patching an original rom binary file (10c, 11c ,16c(buggy)) into address 4800-77FF on a rev2 leaving the nut emulator in situ:

There may be a 12C rev2 that has the Nut ROM image at 4800-77FF, but that doesn't seem to be the case for the 2015-01-30 firmware, which has the Nut ROM image at 480c-780b (in the calculator), or 080c-380b (in the .bin file, because it gets programmed into the hardware starting at 4000). Note that this is not aligned to a flash page boundary.
