I wish I could take credit for the amazing video that follows, but I can’t, so I just want to share it with everyone that follows Tech Powered Math. It’s from the YouTube channel TanRu Nomad, a great channel I’ve been subbed to for a while that covers retro games and computers. The video shows off a Friden EC 130 Calculator, the world’s first solid state calculator. There’s nothing I can say that can better explain or build on this video, so please watch and enjoy.
