The Imperium Romanum HyperCard stack was created by Paul Gries and James Wyatt, who did almost all of the programming and most of the writing. Additional contributors include all of the members of the original Imperium campaign: Matt Lewkowicz, Doug Leonhardt, David Silbey (who contributed a few lines of code), Koeunyi Bae, Mark Lawrence, Margy Baker, David Lieb, and David Wallenstein, whose characters, adventures and ideas are all reflected herein.

James Wyatt converted the HyperCard material to HTML.
