The Apollo Guidance Computer is a pivotal part of computer history, and it was a key part of making it possible for Apollo to land on the moon. And elsewhere on youtube a team of electronics wizards have been trying to resurrect a computer that was scrapped 50 years ago, and I was lucky enough to turn up at the exact moment they got everything running on its original hardware.
You should make a point of watching Curious Marc's multi part series on their quest to bring this computer back to life - 50 years after it was originally built.
