In some of the
documentation, the sketch of a joystick was clearly
the Radio Shack Coco joystick (which needed a different connector)
And is electrically different.
The Tandy 1000 series has Color Computer joystick ports (and the
TRS-80 card-edge parallel port). I've read that some software is
incompatible with CoCo joysticks, but don't remember seeing any such
with my 1000SL.
