According to Going Ahead with Extended Color Basic, page 195 it, uh, *was*:
    0 - horizontal left
    1 - vertical left
    2 - horizontal right
    3 - vertical right
 
So Tandy reversed this in the CoCo3?  If so, I'm sure it wasn't a conscious
decision on their part, given their supposed desire to maintain backwards
compatibility... think about their hires interface. Those "instructions" say to
use LEFT & CASS. Now that's broken, you have to use RIGHT & CASS?

I've been writing Basic code since the early 80's and always remember the left
joystick being first (0/1). Maybe that's why I never paid that much attention
to it... just plug into the other port if a program didn't see it at first,
which somehow always managed to be the case.

That always annoyed me about CoCo programs. That's why I have FOG detect which
one is being used instead of forcing the user to unplug/replug/start cussing
somewhere in between.

Oh well, enough digression. I learned something new today, Thanks Robert.
