JRA PAT and Super Famicom Modem [スーパーファミコン専用 通信モデム]

About 2 years ago, Vinnk purchased a strange controller and a Super Famicom Modem by NTT (スーパーファミコン専用 通信モデム [NDM24]) but just recently he found some software to actually use it, a “game” called JRA PAT (Japan Racing Association Personal Access Terminal). Vinnk explorers this rare and mostly forgotten peripheral, and discovers some interesting facts about it.
