This seems to be an earlier version than the one that included the One Lousy Point Donald Woods Stamp (a tribute to one of the authors of Adventure). Isn't there another version of the later Zork source code in MDL floating around, that has the Don Woods Stamp?
I worked with him at Sun on NeWS -- he's a great PostScript hacker! When you logged into his workstation, /etc/motd said "Welcome to Adventure. Would you like instructions?" -- but don't type "yes" to the Unix shell or you'll regret it. Here's his implementation of QuickSort in PostScript, and he also wrote the Spider card game for NeWS that shipped with OpenWindows (which is a nice clean well documented example of NeWS PostScript code), and he wrote a bunch of Open Look widgets and user interface plumbing for The NeWS Toolkit, too:
Here's a great interview with Don Woods from GET LAMP, in which he mentions playing Zork at MIT over the ARPANET. He describes the point at which he stopped playing Zork, when he had almost solved the entire game, but then they added a whole bunch of new stuff to the game that night. So he realized he would never completely solve it, and finally stopped playing.
I presume the "One Lousy Point" stamp is a cheeky tribute to Don Woods' ordeal playing Zork, because it's so damned hard to figure out how to find it (which I won't spoil):
It's a very early version. Zork development began arund June 1977, so this is just six month in.
I believe the officially final version is from 1981, and is the one Bob Supnik distributes. Macsyma developer Eric Swenson made off with a 1979 version, but it's virtually identical. I'm not aware of any more preserved versions beyond these three.
