This is a stack I created using externals from the Bantam book "Cooking with HyperCard 2.0" copyright 1990 by Dan Winkler and Scott Knaster. This stack was created using HyperCard 2.0 and will not work with older versions of HyperCard. This stack runs fine with HyperCard 2.0 running with system software release 6.0.5, but I don't know if it will work with newer versions of the Macintosh OS.
