Apollo-11

Original Apollo 11 guidance computer (AGC) source code, in assembly, for Command Module (Comanche055) and Lunar Module (Luminary099). Digitized by the folks at Virtual AGC and MIT.

####Attribution

 Copyright: Public domain.
 Filename:  CONTRACT_AND_APPROVALS.agc
 Purpose:   Part of the source code for Colossus 2A, AKA Comanche 055.
            It is part of the source code for the Command Module's (CM)
            Apollo Guidance Computer (AGC), for Apollo 11.
 Assembler: yaYUL
 Contact:   Ron Burkey <info@sandroid.org>.
 Website:   www.ibiblio.org/apollo.
 Mod history:   2009-05-06 RSB  Transcribed from page images.

 This source code has been transcribed or otherwise adapted from digitized
 images of a hardcopy from the MIT Museum.  The digitization was performed
 by Paul Fjeld, and arranged for by Deborah Douglas of the Museum.  Many
 thanks to both.  The images (with suitable reduction in storage size and
 consequent reduction in image quality as well) are available online at
 www.ibiblio.org/apollo.  If for some reason you find that the images are
 illegible, contact me at info@sandroid.org about getting access to the 
 (much) higher-quality images which Paul actually created.

 Notations on the hardcopy document read, in part:
