Gamasutra has now published my article on the History of Zork! Go check it out; it's loaded with plenty of facts, screenshots, and quotations from the authors. I had earlier promised to offer the interviews I conducted with the implementors and other folks here on Armchair. You'll find them below, organized more or less in a "round table" progression. Enjoy!
As some of you may know, I've been a bit busy of late drafting a retrospective piece about Zork for GamaSutra. Although I initially had problems getting in touch with the famous "imps" (Zork programmers, short for "implementors"), I finally managed to hit the jackpot. I've got interview material with Marc Blank, Steve Meretzky, Nick Montfort, and hopefully Dave Lebling (waiting for response).
