Apollo 11's Guidance Computer Source Code Lives on GitHub with 74k Stars and BURN, BABY, BURN

lxfater · x · 2026-10-12

The GitHub repo chrislgarry/Apollo-11 (74.4k stars, 8.1k forks) hosts the original Apollo 11 Guidance Computer source code for the Command Module (Comanche055) and Lunar Module (Luminary099), transcribed from scanned paper printouts, with translated readmes in 30+ languages including Chinese.

Browsing the files reveals AGC assembly code with comments. The most famous easter egg: the lunar module engine ignition routine is named BURN, BABY, BURN — a cheeky name for a serious job. Even without knowing assembly, the file names and comments make for a fun read.
