Source Code
|
This is a reconstructed version of Luminary 130, the initial AGC program released
in November 1969 for the Apollo 13 LM. Three more releases
followed before the flown revision was finally manufactured in February 1970.
This reconstruction was created from a previous transcription of the original listing of
Luminary 131, combined with Luminary memo #129 which describes the small difference
between the Luminary 130 and 131. The reconstructed source code was verified by
matching memory-bank checksums to those listed for Luminary 130 in drawing 2021152G.
In this source code, program comments from the original (Luminary 131) code are
prefixed with '#', while those added later by the Virtual AGC project are prefixed
with '##'.

058399,000004: ## Purpose: A section of the reconstructed source code for Luminary 130.
058400,000005: ## This was the original program released for the Apollo 13 LM,
058401,000006: ## although several more revisions would follow. It has been
058402,000007: ## reconstructed from a listing of Luminary 131, from which it
058403,000008: ## differs on only two lines in P70-P71. The difference is
058404,000009: ## described in detail in Luminary memo #129, which was used
058405,000010: ## to perform the reconstruction. This file is intended to be a
058406,000011: ## faithful reconstruction, except that the code format has been
058407,000012: ## changed to conform to the requirements of the yaYUL assembler
058408,000013: ## rather than the original YUL assembler.
