Lambda the Ultimate

A blog post announces that some of the source code for the Apollo 11 spacecraft has been put online.

On this day 40 years ago, Neil Armstrong and Buzz Aldrin became the first humans to walk on the Moon. This was quite an achievement for mankind and a key milestone in world history.

To commemorate this event the Command Module code (Comanche054) and Lunar Module code (Luminary099) have been transcribed from scanned images to run on yaAGC (an open source AGC emulator) by the Virtual AGC and AGS project.

Since we LTUers spend a lot of time talking about the highest of the high level languages it's illuminating to see how much was done with so little. The source also shows that flying to the moon is really not that different from the kind of programming most programmers do every day. Note the comments.
