It takes a bitmap structure, and 'flips' the bitmap on the Y axis. I also have one that flips a bitmap in the X direction. As for speed: I have a 704X240 one bitplane workbench screen up, and I can flip the screen ~15 times a second in the Y direction- about 20 times a second in the X direction. If anyone wants it, then email me, or if enough people want it posted, then I will... P.S. I also have an extremely fast 2,4, or 8 power zoom that works on bit bondaries, if anyone is interested.
