HyperCard 2.1 is unavailable for inclusion on this CD, due to an aggreement between Apple and Claris to transition bundling “play only” versions of Claris software with Apple products. If you do not have the full version of HyperCard 2.1, the “play only” version of HyperCard is included on this edition of Apple Media ToolKit and will enable you to run the HyperCard navigation stack.
