Non TI-99 game controllers on TI-99 part III

I have found and purchased a product that is going to make testing all the different DB9 (9-pin) game controllers on the TI-99/4A

With screw tightened connections, wire can be swapped easily to try different connections.  There are more condensed versions of these plugs, but for testing purposes only, I think this will work great.  

Additionally I now have the pinout of the Colecovision Flashback controllers. 

Pin  Use          
1    Down
3    Common/Ground
4    Up
8    Right
9    Left




It will take a while to get these parts to me via mail, so I'll pause this topic here.
