[Coco] Testing CoCo 2 joystick ports

[Russ Bernhardt]

I've constructed a basic joystick plug with a 6-pin plug and jumper wires at the end so I can experiment connecting different things but I can't get a simple button test working. 

I've confirmed no shorts and my test consists of looping in basic printing button(0) while touching ground (3) and fire1 (4). 

The only output I get is "0" no matter if I use left or right joystick ports... I even swapped pin 4 and 2 in case I reversed them but no dice.

Any hints?
