I don't follow this reasoning completely.
Since the interrupt routine is called twice, I need to know in my routine if I need to call address #281 or #28F. In your example it will always call #281, right? I would expect some examination of the AF register, or FRAMES to determine which one of the 2 addresses to choose.
Or are you handling the complete screen, basically omitting the second interrupt?
