How big is the APD buffer? Is it the size of GRAPH_MEM? (i didn't see
the size in 82-ram.txt) Does the calculator crash when ON is pressed
because i am using KEY_HAND instead of GET_KEY? What are the
advantages of programming for CrASH (besides the ON key thing)? What
is the advantage of using KEY_HAND instead of GET_KEY, or vice versa?
Sorry for so many questions...
