Setting up the IRQ and handler would (haven't counted) add some bytes when compared to simple polling with all IRQs disabled. Especially if I wanted to have the library routine be non-destructive for whatever is already set on the machine at given time. Yeah, I know I am not going to verify the state of IRQ flag ;-) If that's your primary goal than your VIC solution will indeed be the best. But probably to use the $D012 register, you would need to turn the display on - this is also possibly invasive. Regards, Michau.
