Lunar Landing Game Related Documents

Following a number of articles in 2009 about the history of computer games, I had a number of requests for old documents relating to the Lunar Landing Game; here is some stuff from an old box of TTY tapes and printouts, along with some related things.

2019 Lunar Lander Simulator
In September 2019 Stefan Trenkel published a web simulator for Lunar Lander:
He said that the code was implemented to operate as close to the original code as possible. In fact when run using the same numbers as the two original sample outputs shown above, the results are nearly identical. Here are screen shots (for the second game, the mistake of first typing a zero instead of the letter O to type NO was duplicated):
Lunar Landing Game Simulator Sample Output - fail

Lunar Landing Game Simulator Sample Output - success
Playing on the simulator reminds one that, although it is a very simple user interface, the game is not so easy to win if you have not already seen others play. Here some screen shots. The first always chooses 75 fuel rate and results in a crash with fuel left, and the second always chooses a 76 fuel rate and results in a crash with no fuel left. The third screen shot shows a horrible game where fuel was aggressively used (even mistakenly trying to use more that a rate of 200) and it ends with the lander briefly rising up, running out of fuel still at a high altitude, and then free falling and crashing hard.
Lunar Landing Game Simulator Example - fuel left

2020 Lunar Lander Translations
Here are some Lundar Lander translations created by Kristopher Johnson in 2020; I tried the c program and it compiled and ran nicely in a terminal window on my mac.
