This is a triple-fat version of Thoughtful Software's multi-purpose HyperSense authoring system (for NeXT, Intel, and HP PA-RISC architectures). It is fully functional in demo mode except that no changes or new documents are saved to disk. Most pre-existing documents are fully usable in demo mode. Contact Thoughtful Software to purchase a license in order to run fully registered without restrictions.
For proper operation, both the App and Docs packages should be installed.
