This adapter allows you to connect a Standard Atari 9 pin Joystick to your Tandy TRS80 Color Computer (CoCo) 1, 2, 3 or Dragon 32, 64 computers. 

No configuration necessary as this is plug and play.   The Color Computer/Dragon computer will see it as an analog stick.  Some adapters that are being sold on eBay only work with 1 button controllers as Atari controllers only have one button, however if you are able to connect button 2 to pin 9 on the 9 pin joystick connector, this will also work with 2 buttons.

The adapter accepts a standard 9-pin Atari. joystick plug and converts the digital signals in to the analogue input required by the TRS80 Color Computer or Dragon 32/64. It does this by acting as two voltage splits, one for each axis.

This comes with a 3D printed case in white and it is assembled and shipped from the US.  You will not have to wait weeks for it to arrive from overseas.

These are made to order, so it will take a couple of days to get them built and shipped out.

You can also pair this with one of my custom Atari competition pro inspired controllers:
