I don't believe there is a horozontal blank interrupt. I have heard that you can fake it via. timer interrupts and a phase-lock-loop to trigger the palette change. However you can't even modify 256 colors during vertical blank fast enough, most VGA cards "farkle" when you do this (direct register writes). Good luck Doug… William Volk
