Colecovision Champ adapter Joystick?

[thegamezmaster]

Does anyone know what joystick works with the Colecovision Champ Keypad Adapter? Looking for the model number of joystick and what brand. Tried Google and could not find anything. I appreciate any help, thanks.

It should work with any Atari-compatible controller, I think that was the point of the keypad adapter in the first place. You might be able to use a 7800 controller for two-button support but I don't know if the keypad adapter is fully wired or not.
