Original Apollo 11 guidance computer (AGC) source code for Command Module (Comanche055) and Lunar Module (Luminary099). Digitized by the folks at Virtual AGC and MIT Museum. The goal is to be a repo for the original Apollo 11 source code. As such, PRs are welcome for any issues identified between the transcriptions in this repository and the original source scans for Luminary 099 and Comanche 055, as well as any files I may have missed.

    Check continuity on O2 cryogenic tanks before allowing stir

    A customer has had a fairly serious problem with stirring the cryogenic tanks with a circuit fault present. To reproduce:

    1. Build CSM
    2. Perform mission up to translunar coast
    3. During translunar coast, attempt to stir cryo tanks

    If a wiring fault exists, the issue may be replicated. Be aware that this may be hazardous to the tester attempting it.

  • Handling Issues

    Handling Issues

    Im currently working on the best way to deal with recent influx of issues. It seems there arent any features for dealing with this problem in bulk, so I submitted a feature request to bulk flag/delete in the UI (pretty sure it can be done using the API via a simple python script) and to limit issue creation etc. to accounts older than age X. Ill close this once we have a long-term solution. Unfortunately, those who want to watch our repository are being bombarded with nonsense notifications, so this is important. Its important to note that most of these issues are jokes which are ok, but this could become problematic if it gets out of hand.

  • Query about blank lines

    Query about blank lines

    After checking about 10% of the CONIC_SUBROUTINES.agc file, I've noticed that the digitisation is only using empty lines on lines marked as R0000 and ignores fully blank lines. However, outside of this file I've noticed in many places these fully empty lines have sometimes been included - the usage seems pretty inconsistent.

    Which would be best to make this as accurate to the source files as possible?

    cc @chrislgarry @rburkey2005


    Example (Page 1266

    This page has a mixture of empty lines marked with R0000 and empty lines with no line number.

    The raw digitalised file has only used the R0000 empty lines (plus an erroneous blank line within the list)

    Vs. this version that includes the empty lines with no line number

  • Fix all the typos

    Fix all the typos

    Thanks to Hunspell and no thanks to the RSI that I have now from repeatedly hitting Alt+N, I do believe I have corrected most of the typos.

    I have also squashed some of the other PRs that have been verified onto my commit, although I improperly applied radarhere's PR by downloading it as a diff and then committing it myself, so if anyone wants me to do it properly, just ask. It's best, however, to just merge radarhere's branch first and then merge mine second, and then rebase it with radarhere's commit to drop my fake commit.

    Let the peer review begin!

    Transcription and Transposition Fixes

    This PR will be checking through all the pages related to the first ~~10~~ 4 files in the Comanche055 directory.

    Changes in the PR include fixing typos introduced in the transcription process and also those fixed by the transcription process. Transposition errors, such as full stops, extra spaces (or lack of extra spaces) etc. I've also removed/added blank lines to match the original source images.

    Apologize for spammed Chinese issues | 为一些中文(spam) Issues 致歉

    As you can see, there are some low quality chinese issues. As a chinese student I want to apologize first.

    But please believe that uncivilized chinese people are only a few. There are many people in China who love technology and are willing to share it. We want to build an excellent community together.

    Forgive me for poor english :(


    正如你所见,Issues 有一些低质量的中文条目。作为一名中国学生我想先向各位道歉。

    但是请相信,不文明的人只是少数。有许多的中国人民热爱技术、乐于分享。我们希望一起建立一个优秀的社区。

    This PR is the third and last part of proof-reading Comanche055 P40-P47.

    @wopian In line 2300 (line 2330 before my edits), there seems to be a single line of code that doesn't appear in the scans. I couldn't really figure out what that's about by checking the file history on Github, so I left it there for now since it might be important.

    • Fixed one character typo in code on line 344. (I think someone read number 8 as a 6)
    • There is something weird at line 624 - a portion of the comment was not in the scan but appears in the file on Github. My change makes it match the scan exactly, but it appears that the comment might be "cut off" (?)
