Source Code
|
These source-code files are part of a reconstructed copy of Luminary 173, the
second (unflown) release of the Apollo 14 Lunar Module (LM) Apollo Guidance
Computer (AGC) software.
The reconstruction began with reconstructed source code for Luminary 178. Changes
between revision 173 and 178 were backed out, as described by Luminary memo 167
(revision 1). The reconstruction was verified by matching memory-bank checksums
to those listed in drawing 2021152N. Note that page numbers in the reconstructed
code match those for the baseline log section mentioned in each file's changelog;
the page numbers for a real Luminary 173 listing would be different.
Comments from the original source code are prefixed with a single '#' symbol,
whereas comments added later are prefixed by "##" or "###". Report any errors
noted by creating an
issue report at the Virtual AGC
project's GitHub repository.

036449,000003: ## Filename: ASCENT_GUIDANCE.agc
036450,000004: ## Purpose: A section of Luminary revision 173.
036451,000005: ## It is part of the reconstructed source code for the second
036452,000006: ## (unflown) release of the flight software for the Lunar
036453,000007: ## Module's (LM) Apollo Guidance Computer (AGC) for Apollo 14.
036454,000008: ## The code has been recreated from a reconstructed copy of
036455,000009: ## Luminary 178, as well as Luminary memo 167 (revision 1).
036456,000010: ## It has been adapted such that the resulting bugger words
036457,000011: ## exactly match those specified for Luminary 173 in NASA
036458,000012: ## drawing 2021152N, which gives relatively high confidence
036459,000013: ## that the reconstruction is correct.
036460,000014: ## Reference: pp. 834-849

036464,000018: ## Mod history: 2019-09-18 MAS Created from Luminary 178.
036465,000019: ## 2019-09-21 MAS Moved initialization of ZAXIS1 back to P12.
036466,000020: ## Changed ASCSAVE to share with CG.
