This cart was used to bet on horse racing, using a NTT modem. The cart isn't really emulated at this point. These horse betting carts came in a black shell. There are three versions of JRA PAT, though at this point it is unknown how they differ. Apparently NTT released new versions of the cart every few months. The first version has a serial code of TJAJ, the second version is TJBJ and the third version is TJCJ.
