If anyone wants to learn more about the Apollo Guidance Computer, this talk[1] from 34C3 will teach you everything you wanted to know and more. The AGC had some really fascinating features for the time, including a cooperative multitasking system, interrupt driven IO, and even a virtual machine for doing linear algebra! [1] [VIDEO]

The best presentation I have seen on the AGC architecture: [VIDEO] It does present addresses in hexadecimal, oddly. The computer was 15-bit and used octal in its display panel. I suppose the presenters thought the audience would understand hex better.

Michael’s blog is one of my favorites. His “Ultimate Guide” talks are great and I rewatch them at least once a year. Ultimate Guide to the C64: [LINK] Ultimate Guide to the Game Boy: [LINK] Ultimate Guide to the Apollo Guidance Computer: [VIDEO]

This is amazing to see - completely unpotted AGC! I've been following Curiousmarc's channel for a while and it's great to see this. Anyone interested in AGC stuff might also want to check out this video from the 34th Chaos Communication Congress that exhaustively explains how it works: [VIDEO]
