I have a Pitfall 2 pcb like the one on this picture

Mine has 3 sega custom ic's, the pcb number is:834-5627-11.
The only odd thing is the Activision sticker with the serial number, it says: Pitfall II- The Lost Converns.
Is it a very well produced boot or an original?

Found another odd thing: The sticker on the main pcb with the number on it says pit fall instead of pitfall 2
