[A89] Intercepting ON



I am working on a TSR that will intercept when someone presses 2nd+ON (in 
otherwords, when someone turns the calculator off) and runs some code before 
turning the calculator off. However, I have read that the ON key is not part 
of the keyboard matrix and is associated with an interrupt. How then, would I 
go about intercepting this before trap #5 (I believe trap #5 turns off the 
calc) is called? Thanks.
