These source-code files were obtained by digitally photographing
an Artemis 72 (Apollo 15-17 Command Module) program listing from a private
collection and then
modifying pre-existing Comanche 55 (Apollo 11) source files to
incorporate changes. Photography was by Ron Burkey, and transcription
was performed by a team of volunteers. 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.
