Pro Tools SE 8.0.3 - Patch 003

Pro Tools 9.0.5 is supported, and I know from experience that Pro Tools 7 and Pro Tools 6.0.3 is supported as well, so I'm going to take a shot in the dark and say, Pro Tools 8 is most likely supported under 10.6.8 with the correct supported USB hardware interface (maudio for instance)
