A simple method would be to just poll $C000, then place JSR's to this routine where you would want the keyboard to be interrupted.  Say, after a page of text is displayed or even throughout your code at various places.

Another method is to just put a $00, after the code you want to check out.  It has the added benefit of displaying the registers.


  BIT $C000
  BPL RETURN

  LDA $C000
  BIT $C010
  CMP #$83
  BNE RETURN
 
  JMP $FF69  ; for monitor of $3D0 for Applesoft

RETURN RTS
