#2Most of this is code is available in machine-readable form in the VirtualAGC Google Code repository:

Re: Apollo program source code
#3Fun fact: the actual programs in the spacecraft were stored in core rope memory, an ancient memory technology made by (literally) weaving a fabric/rope, where the bits were physical rings of ferrite material.

#4hmmm. so the "bugger words" at the end of, for example, http://www.ibiblio.org/apollo/listings/Colossus249/MAIN.agc.... are checksums - see http://books.google.cl/books?id=3fKzL0HfJp4C&pg=PA232...
anyone know the etymology? is it just a shortened form of "debugger"? is "bugger" not common slang in american english? or is this a joke?

Bugger is not common slang in American English. You can find people who will argue about that, but they don't get out much.

"Core" memory is resistant to cosmic rays. The state of a core bit will not change when bombarded by radiation in Outer Space. Can't say the same of solid state memory.
I worked on core memory computers in the 60's. You had 16K, tape drives (no disks) and FORTRAN. What a gas!

#7looking through some of those documents a couple things stand out to me:
1) learn your maths people if you want to do rocket science stuff
2) the amount and detail of the documentation they wrote back then is unreal
3) the simple webapps I write for big bucks at local megacorp pale in comparison to those programs that frickin landed people on the moon!

#8With the power of open source, "many eyes make all bugs shallow".
Wouldn't be a hoot if someone ran this through a simulator, and discovered a bug that had eluded NASA?

#9Just in time for being ported to DCPU-16.

Exactly ...
