A HyperCard discovery has unearthed a rare Voyager Expanded Books edition containing William Gibson's Sprawl Trilogy: Neuromancer, Count Zero, and Mona Lisa Overdrive. This 1991 digital release includes an exclusive afterword by Gibson not republished elsewhere, though copies have circulated online. The Voyager Company pioneered digital book presentation during the early 1990s, focusing on typography and reading experience.

The installation process reveals the technical constraints of early digital publishing. Users must mount a 1.4 MB floppy disk, run compatibility checks, and install custom fonts to their System folder. The software requires System 6.0.7 and HyperCard 2.1, designed specifically for Macintosh PowerBooks with 640x400 displays or larger. Novels appear alphabetically rather than chronologically in the library interface.

This find demonstrates how early digital publishing experimented with interactive literature. The Expanded Books Project's attention to font choice, spacing, and bookmarks foreshadowed modern e-readers. Running on Basilisk II emulation with System 7.5.5, this HyperCard-based implementation represents a fascinating intersection of cyberpunk literature and 1990s multimedia computing.
