Great to see the AGC assembly code and knowing that Apollo 11 is coded purely in assembly. Not sure if it has any compiler. Also found https://github.com/virtualagc/virtualagc while searching for compiler.

Part of the AGC ROMs implemented a virtual machine for things like matrix multiplication. So, a higher level of abstraction was available but it was still very much coded in its own assembly language.

In 1969, they had not invented lowercase yet.

Really cool to see this digitized and archived, it's such an important piece of history and really one of the earliest digital ic bases computers.
