Virtual Apollo Guidance Computer

#1
The purpose of this project is to provide an emulation of the on-board Apollo guidance computers, along with some ancillary items needed to make the emulation do something interesting. "AGC" stands for Apollo Guidance Computer. The AGC was the principal on-board computer for NASA's Apollo missions, including all of the lunar landings.

Is this the same software Curious Marc is using to emulate a DSKY/AGC for their apollo comms project? Or are they using something custom spun up to support the hardware they are working on?

Mike Stewart, that is the one with the most in depth knowledge about the AGC on the Curious Marc channel, is also one of the main contributors to this repo, so I guess so.

"Mike Stewart has developed gate accurate FPGA replicas of the AGC and its test hardware. It represents a massive amount of work. If you are Mike, you can use it to fly the real missions, and simulate every signal in the AGC. Making this work is not for the faint or heart and requires intimate understanding of the AGC hardware and software. We offer no instructions and no support."

Thanks! I took that as an excuse to make a longer list—this includes hardware stuff and other history, besides software:
