This is a rare module for a Coca Cola vending machine from 1985. Think “ New Coke” fiasco. I bet this was a gimmick to lure customers back. Slogan was “Win with # 1”. Identified with Sanyo RLT-700US ID tag. I have found nothing on it after much research. I usually can find something but got nowhere. Could be a rare collectible if few exist.
