Hi TjLaZer,
To my knowledge Airball only works on 512K of Chip ram. So, you will have to use an Amiga 1000 or an Amiga 500 or 2000 with a revision 4.x motherboard. I could email you the Atari ST version of Airball. :-D
My Amiga 500 Tower runs Airball, but only when I turn off the second 512K of Chip ram. :-)
