2-in-1 Controller Splitter

The Reverse Y Joy Stick Reducer was a clever adapter from the early 1980s designed for systems like the Atari VCS, ColecoVision, Sears Tele-Games, and Commodore VIC-20. Its purpose was to let two players share a single joystick while keeping their scores separate — a neat workaround for consoles that didn’t support simultaneous two-player input.
