Ben Eater starts a series building a working computer on breadboards around the 6502 microprocessor. In this first part he gets a 'hello world' running from scratch.
HN repeatedly recommends it as the best hands-on way to understand how a CPU and a computer work from first principles.

I found the „Hello world from scratch“[1] series from Ben Eater incredibly helpful in connecting the dots between electricity and modern computers. Strictly speaking it is about electronics, still it is superbly presented and incredibly enlightening when coming from „normal“ software engineering perspective of things. What actually got me there was the book „Code“ by Charles Petzold[2] which traces the development from early circuitry like light bulbs and telegraph wires to modern digital logic. I found that after being introduced to these concepts, learning about the fundamental physics was much more accessible since it was framed in the context of contemporary application. 1: this video 2: [LINK]
After stumbling on Ben Eaters “Hello world from scratch” [1] I went out and bought the cpu some parts and breadboards. The chip is only a few dollars. It is highly recommended if you want to dive down into computers and digital logic on first principles. Also great fun to get a break from all the screens and layers upon layers of software that I have to deal with daily. 1. this video
The (awesome) youtube electronics teacher Ben Eater has just started a series of videos building a 6502 based computer on a breadboard, and he sells kits. I just got my kit, so I'm really looking forward to the rest of the videos. He also offers the schematics for those wanting to jump ahead. this video [LINK]
For anyone interested in the 6502, assembly and just in general how things like loops, conditional branches, hardware communication, etc all work, I HIGHLY recommend Ben Eater's videos on the subject: this video They are incredibly fascinating!
Here is an amazing video on how to build a computer based on 6502 on a breadboard, and program it in binary to get a Hello World equivalent. I highly recommend it: this video
