Oh, apparently people like Zork a lot! Well, let me walk you through what the Internet Archive has lying about to make your Zork memories or soon-to-be-memories come alive. 
Well, first, did you know I did a documentary on text adventures? getlamp.com
If you want to read much of the behind the scenes memos, discussions, company efforts and information about Infocom, I scanned thousands of pages from the notebooks of Steve Meretzky and you can browse them here: archive.org/details/infoco…
If you want to browse through a bunch of Infocom source code, go visit this github repository. Has a bunch of other games as well, both ones I helped recover and many others people have been quietly putting on github for years. github.com/historicalsour…
Did you want to PLAY Zork? Well, sure. How about playing it on an emulated black and white Macintosh off a hard drive with all the old Infocom games?
