From Transistors To Tetris Part 1 : Computer Architecture

My dad was an TV repair technician. I would watch with fascination when he would take apart televisions and radios and see the circuit boards that brought these inanimate objects to life. Here’s a YouTuber who is doing something similar (kind of) I’ve been building a 1970’s era computer out of discrete transistors for the […]
