# Purpose: Part of the source code for Luminary 1A build 099.
|
|
# It is part of the source code for the Lunar Module's (LM)
|
|
# Apollo Guidance Computer (AGC), for Apollo 11.
|
|
# Assembler: yaYUL
|
|
# Contact: Ron Burkey <info@sandroid.org>.

# Website: www.ibiblio.org/apollo.
|
|
# Pages: 244-261
|
|
# Mod history: 2009-05-10 SN (Sergio Navarro). Started adapting
|
|
# from the Luminary131/ file of the same
|
|
# name, using Luminary099 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.
|
|
