Since you are interested in practical examples, I would recommend you watch and maybe even follow along with Ben Eater’s 6502 breadboard computer series on YouTube (piped link). The kit is cheap and works great but more importantly it introduces so many core concepts about how computers actually work from a raw metal and machine code standpoint while touching on so many different aspects about computers that still apply today.
A reverse proxy will solve this for you in an afternoon of setup :)
