This is a disk image HyperCard 2.4.1 installed on Mac OS 8.
It also includes a Mac Quadra 950 firmware image required by all Mac emulators.
How to use:
1. Install Basilisk II, a Classic Mac emulator. Others may work, I have not tried them.
You can get the Windows version here:
Or a version for real operating systems here:
2. Unzip the archive. You will get:
hypercard-on-sys8.img - this is the disk image to use with Basilisk (or other emulators.)
quadra950.rom - this is the hard-to-find Mac ROM image required by the emulator.
3. Attach the firmware file and the disk image to Basilisk.
4. Boot from the disk image.
5. Enjoy HyperCard!
