Source Code
|
These source-code files were obtained by digitally photographing
an Artemis 72 program listing from a private collection and then
modifying pre-existing Comanche 55 (Apollo 11) source files to
incorporate changes. Note that the page images
presented online are of reduced quality, and that additional images
may be available. Report any conversion errors or legibility
problems in page images to info@sandroid.org.
Notations on the program listing read, in part:GAP: ASSEMBLE REVISION 072 OF AGC PROGRAM ARTEMIS BY NASA 2021114-011 11:40 FEB. 26, 1971 THIS AGC PROGRAM SHALL ALSO BE REFERRED TO AS COLOSSUS 3 THIS PROGRAM IS INTENDED FOR USE IN THE CM AS SPECIFIED IN REPORT R-577.
