# Copyright: Public domain.
# Filename: P32-P33_P72-P73.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: 649-683
# Mod history: 2009-05-09 RSB Adapted from the Luminary131/ file
# P32-P35_P72-P75.agc and Comanche055 page
# images.
# 2009-05-20 RSB Corrected CSI/COM3 -> CSI/CDH3,
# CSI/CDHI -> CSI/CDH1, CDHTAB -> CDHTAG,
# changed a SETLOC from CSI/CDH to CSI/CDH1,
# a SETLOC CSI/CDH1 to CSIPROG.
# 2009-05-21 RSB Changed a P32/P72D to P32/P72E in
# P32/P72D. DP1/4TH changed to DP1/4 in
# CDHMVR.
#
# 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.
