From the project
Open-hardware RGB mod for the Emerson HKTV13 "Hello Kitty" CRT TV — an interposer board that injects switchable external RGB while preserving the original OSD.
An open-hardware RGB injection board that adds clean, switchable RGB input to the Emerson HKTV13 Hello Kitty CRT television. The module is an interposer that sits between the TV's neck board and main board, in line with the existing 7-pin OSD link. It either passes the original OSD signals straight through, or pulls them out and injects external RGB in their place — letting you feed RGB from a retro console, scaler, or other source while keeping the set's original on-screen display (OSD) fully usable.
