So I woke up to this incredible news. Jason Scott at the most excellent archive.org had just uploaded the old Infocom source code to github. It’s from the infamous ‘found hard disk’ that has been mentioned going back to the failed game ‘The restaurant at the end of the universe’.
So looking at the repos here, you can see the latest ones are all Infocom. It’s best to get them all via git for reason below:

The reason being of course that if there are multiple versions they are stacked. Now why is this important? Who cares? it’s all in ZILL which there is no compiler for, as the TOPS-20 tools are still lost?
Written by Jesse McGrew in an apparent vacuum, this toolchain can Z3 machine based ZIL source code. Yes that’s right it’s a compiler!
I know Zork will get all the headlines, but back the 80’s I preferred Planetfall. I’m not even going to talk about the insanity that was the Hitchhiker’s guide to the galaxy.
Zilf is really only suited for Z3 compilation, and looking at planetfall there are two commits of note:
$ git log| tail -11 commit e85ca899aac575e74a4b3845f44d09a891c1563a Author: historicalsource <[email protected]> Date: Sat Apr 13 21:35:51 2019 -0400 Final Revision commit 281bd3417faada8011397244d4bfaad562cb7bfc Author: historicalsource <[email protected]> Date: Sat Apr 13 21:34:42 2019 -0400 Revision 37 (Original Source)
The source for the Final version won’t build with ZILF. However the Revision 37 source will!
$ git checkout 281bd3417faada8011397244d4bfaad562cb7bfc Note: checking out '281bd3417faada8011397244d4bfaad562cb7bfc'. You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by performing another checkout. If you want to create a new branch to retain commits you create, you may do so (now or later) by using -b with the checkout command again. Example: git checkout -b <new-branch-name> HEAD is now at 281bd34... Revision 37 (Original Source)
Ok, now let’s trash the directory! (you did backup the repo first, right?)

Sure it said 4 errors, but it compiled! Using a z3 or higher interpreter we can load up Planetfall
At first glance it may look the same, but check the serial number. 190417. That’s today!
I’ve played it about 1/5th of the way though. There is a walkthru here.
There seems to be so much in flux about this source dump. replicate while you can!
