Apple announced HyperCard¿ IIGS¿ for the Apple IIGS¿ personal computer in
December 1990. The program was made available in February 1991 through
authorized Apple dealers in mid-February 1991. The program comes with nine
ready-to-use stacks.
HyperCard IIGS has the full functionality of Macintosh HyperCard version
1.2.5--plus enhancements to improve performance and take advantage of the
color capabilities built into the Apple IIGS. Users can also access the
many stacks that already exist for the Macintosh, once developers convert
them for the Apple IIGS.
To use HyperCard IIGS, you need an Apple IIGS with at least 1.5MB of RAM
(2MB is recommended), system software 5.0.4 or later, one 800K disk drive,
and a hard-disk drive (or connection to a network). HyperCard IIGS is sold
only as a stand-alone kit with six program disks and three manuals.
