The Electronic Whole Earth Catalog is an early CD-ROM presenting The Whole Earth Catalog in the form of HyperCard v1.2.2 Stack media. It consists of over 9000 HyperCard "cards" connected via HyperText and HyperTalk, HyperCard's markup language.
The DL consists of a zipped "iso" CD ROM image file. Once extracted, mount the Whole Earth Catalog's "iso" image folder onto a running Macintosh Desktop and double-click "HyperCard" (or "Home") to launch.
This presentation can run from CD ROM, or from the mounted .iso image file.
Included on this CD-ROM image is HyperCard version 1.2.2
This .iso image is suitable for mounting on Macintosh Systems, 5, 6, & 7. - Running this Hyper-media in even later Mac OS's may require using a newer version of HyperCard.
