### FILE="Main.annotation"
## Copyright:	Public domain.
## Filename:	FIXED_FIXED_CONSTANT_POOL.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.
## Pages:	1200-1204
## Mod history:	2009-05-13 RSB	Adapted from the Colossus249/ file of the
##				same name, using Comanche055 page images.
##		2016-12-21 RSB	Proofed comment text using octopus/ProoferComments
##				and corrected the errors found.
##
## 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:
##
##	Assemble revision 055 of AGC program Comanche by NASA
##	2021113-051.  10:28 APR. 1, 1969  
##
##	This AGC program shall also be referred to as
##			Colossus 2A
