Source code for the Apollo 11 Guidance Computer

Not quite sure why this links to the code, and not the top level which has a lot more useful information (such as the simulator needed to run the code).

There's some more information here: http://googlecode.blogspot.co.uk/2009/07/apollo-11-missions-...

Can someone explain what this is? I doubt they had an actual game of pinball in their guidance computer.

It appears to be the code for the controls:

# THE KEYBOARD AND DISPLAY SYSTEM PROGRAM OPERATES UNDER EXECUTIVE

# CONTROL AND PROCESSES INFORMATION EXCHANGED BETWEEN THE AGC AND THE

# COMPUTER OPERATOR. THE INPUTS TO THE PROGRAM ARE FROM THE KEYBOARD,

# FROM INTERNAL PROGRAM, AND FROM THE UPLINK.

I think it's just someone with a sense of humor.

In MAIN.agc there is a list of bugger words. Not that I know assembly in any meaningful way, but I've never come across this term before.

On Googling, it seems to be something to do with a checksum value?
