#
#	YUL SYSTEM FOR AGC: REVISION 0 OF PROGRAM BURST120 BY NASA 2021106-031
#	DEC 7, 1967
#	...
#	THIS LISTING IS A COPY OF A VERSION OF THE PROGRAM INTENDED FOR USE IN
#	THE ON-BOARD PRIMARY GUIDANCE COMPUTER IN THE UNMANNED FLIGHT OF
#	APOLLO LUNAR MODULE 1 --- THE AS206 MISSION.
#	...
#
# Note that this is the date the hardcopy was made, not the date of the program 
# revision or the assembly.

# The page images themselves, as reduced in size (and consequently in
# quality) to be suitable for online presentation, are available at

# This file is a little different from the other BURST120 AGC source-code files, 
# in that it doesn't represent anything that appears directly in the original source.  
# For organizational purposes, the huge monolithic source code has been split
# into smaller, more manageable chunks--i.e., into individual source 
# files.  Those files are rejoined within this file as "includes".  It just makes
# it a little easier to work with.  The code chunks correspond to natural divisions
# into sub-programs.  In fact, these divisions are more-or-less specified by
# the source code itself.  Refer to the ASSEMBLY_AND_OPERATION_INFORMATION.agc
# file's TABLE OF LOG CARDS.
