IBM keyboard interface for the Tandy Color Computer. Found this in a lonely box in my storage shed while searching for something else. It works!

@sleet01 linear power supply, 7805 regulator steps down unregulated 12vdc to 5vdc. The CoCo's power supply is taxed by design, almost nothing left for any other accessories, hence a tap on the 12vdc out of the rectified transformer secondary.
