[Coco] OS-9 coco2b lowercase

[Arthur Flexser]

I think he was asking if there's a SOFTWARE test for the presence of
true lowercase on a CoCo 2, which might be needed if you didn't want
your software to attempt to throw the CoCo it was running on into true
lowercase mode unless the CoCo had that ability.  (If the CoCo didn't,
the attempt to throw it into true lowercase would result in a bunch of
colorful but undecipherable Semigraphics-6 globs.  Semigraphics-6 was
so useless that nobody missed it when it was replaced by true
lowercase mode on the CoCo 2B and CoCo 3.)

If the presence of Color Basic 1.3 isn't a reliable test, I don't
think one is possible.
