# Comanche055
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.
Notations on the hardcopy document read, in part:
Assemble revision 055 of AGC program Comanche by NASA
2021113-051. 10:28 APR. 1, 1969
This AGC program shall also be referred to as
Colossus 2A
## Background
## Background
For organizatinal purposes RSB split the huge monolithic source code into smaller, more manageable chunks--i.e., into individual source
files. Those files are rejoined as "includes". The code chunks correspond to natural divisions into sub-programs. In fact, these divisions are more-or-less specified by the source code itself. Refer to the `"SUBROUTINE CALLS"` at the very beginning of `ASSEMBLY_AND_OPERATION_INFORMATION.agc`.

that you no longer have to worry about dropping the card deck. On the other hand, I (RSB) wasn't there at the time, so I may have no idea what I'm talking about.
Finally, note that the original Apollo AGC assembler (called `YUL`) is no longer available (as far as I can tell). Actually, it had already been replaced by another assembler (called `GAP`) by the time of Apollo 11, but GAP isn't available either. The replacement assembler yaYUL accepts a slightly different format for the source code from what YUL or GAP accepted, so the source code has been targeted for assembly with yaYUL.
What follows is simply a bunch of file-includes for the individual code chunks. The page numbers have been marked to make proof-reading easier. The page images also contain a lot of interesting tables (cross-referenced to page numbers) created by GAP, but not duplicated by yaYUL, so it's still valuable even if the source-files listed below are in hand.
