Just in case I need to analyze kernel crash dumps under Solaris SPARC ever again, this is CTEact, the infamous act tool.

Dave doesn’t let me upload anything but the pictures and movies (heh!), so this will have to be renamed apropriately.
CTEact 7.17 SPARC, covers Solaris 2.5 through to 8
CTEact 8.2 SPARC, covers Solaris 2.8 through to 10.
