CLEAR  EQU     $F2F3

Page zero location $E6 must be preset to the graphics page you
are clearing: $20 for HGR1 and $40 for HGR2.

$F2F3 clears the current page to black, but you can set the page
to any color by placing a "color byte" in the A register and calling
$F3F4, or by setting $1C to the desired color byte and calling $F3F6.

I'm no assembly programmer, but looking at the Beagle chart (and A2
FAQ), it would seem you both have made the same typo -  isn't the
correct address to call $F3F2, *not* $F2F3?

You're absolutely right.  I read the later entry points off the listing,
but copied the first from the question--they are all adjacent.  ;-)
