That's easy, it's the production code for the game. NES-7Z-USA. The ROMS also are labeled. Including even the EPROM.

ETA: The label also probably says ZL, 7Z is another game that's not zelda, while ZL is the first Zelda.
I feel silly now, if you look closely you can read PAL-ZL-1 on the chip in the side by side photo.

The service center theory above sounds solid. Still I'm wondering why they would put this kind of effort into repairing a cart. The cost for the Eprom alone is probably higher than for a full new cart, isn't it ?
