HyperCard 1.2.5: Disks Are Mislabelled As "1.2.3"

This article contains information about HyperCard version 1.2.5, which has been mis-labeled in some situations as v1.2.3.
Some users are buying Macintoshes and getting disks labeled HyperCard version 1.2.3 -- although the "About" box shows version 1.2.5.

HyperCard version 1.2.3 was an internal testing version and never distributed to the general public as a product.

Despite what may be listed in some publications, the CORRECT HyperCard version for use with the Macintosh Portable and Macintosh IIci, under System Software 6.0.4, is HyperCard version 1.2.5.
