From the project
Tandy Color Computer 3 RGB Port to AppleColor RGB Monitor (IIgs version)
This card will interface the Color Computer 3 RGB port to an AppleColor RGB Monitor (model A2M6014). It was created and shared with the CoCo community. The design is provided here for whatever purpose you would like: make for yourself, build, sell, or modify.
The card was designed from an schematic from 1996 by Tomi Engdahl. The circuit was modified to work with the AppleColor RGB Monitor. Here is the original schematic:
