In 1992, Douglas Adams’ Complete Hitch Hiker’s Guide to the Galaxy was one of the original three Voyager Expanded Books published. A big Mac fan, and a Voyager fan as well, Adams wrote and recorded a short promotional audio for the floppy-disk-based ebook series. Here, in all of its crunchy 8-bit-audio glory, is that recording, Getting the Book Invented Properly.
Bonus: the Literary Platform site recently held a competition for animations to accompany the recording. The entries are here.
