Thanks to Platonic Duck Kitchen patron Chris Sakkas, Enter the Avenger is now listed in the FOSsil Bank of free cultural works and available for download as an EPUB file — for use with various portable e-book reader devices.
While my few experiences of trying to run a game with a digital rulebook (i.e. a PDF displaying on a laptop) instead of a paper one were frustrating enough, I believe Enter the Avenger to be structured in such a way (as an instructions text) that you can run it satisfactorily out of a hand-held device such as an e-book reader or "tablet". Just try to absorb the Special Cases section beforehand, considering how tough such devices usually make it to zap forward and back through a book.
