This is an early version of HyperCard, version 1.0.1. It is a set of four Disk Copy 4.2 images inside a StuffIt 1.5.1 archive.
All the Disk Copy images were made directly from the official original disks, except for "HyperCard & Stacks", which was damaged. Fortunately, the damage only affected the HyperCard program itself, which there was another copy of on the "HyperCard Startup" disk. The image included here for "HyperCard & Stacks" includes all the stacks from the original disk, and the program from the Startup disk, so it should work just like the original.
Added Hypercard D1-1.1 from three original disks as second download.Compatibility
