1 year ago From what I gather, this is technically MIT's dungeon 2.7a. Most of the online maps are for Zork (a later release) or for possibly 3.2a/b which may be slightly different.
I have also noticed there are great differences in the parser and some of the basic content. Walkthroughs never seem to mention which version of zork/dungeon they are using. I have completed about a 50% walkthrough on this specific version (after fixing the RNG in place).
Try this walkthrough as it'll show you some of the differences from the commercial zork: http://www.deblauweschicht.nl/retrogaming/resources/MainframeZork_walkthrough.txt
This may be my own misunderstanding of how Zork is supposed to work, but the game map seems to differ greatly from illustrated maps I'm finding online. Not only that, but it seems entirely inconsistent in its geometry. For instance, if east from Room A is Room B, then west from Room B should be Room A, but it's somewhere else entirely. And this is happening with almost every room for me.
If I'm missing something please tell me!
