Been looking for videos on how to make a CPU from basically the most basic stuff.

Anyone here can tell me how the previous generation was able to create a Central Processing Unit?

Enjoy.

You're welcome.

 

Might not be exactly what you asked for, but he does explain a lot of things related to it.

The basic building block for the CPU itself is a switch. One of the earliest examples of a "programmable" machine that historians generally agree upon is the Jacquard Machine. It was a textile machine that could change patterns based on a series of punch cards. These punch cards were the switch, they controlled whether something happened or not.

 

With electronics, we've created purely electrical switches. First it was vacuum tubes, then it became transistors. By hooking up various transistors together, you could create digital logic. That with a combination of being able to etch transistors into silicon allowed complete circuits to be built into a silicon chip. This allowed us to move from separate whole transistors into chips that contained some functionality. And with technology getting progressively better at etching smaller and smaller transistors, you can integrate more things into a chip.

 

But you can still build a CPU made originally on a silicon chip with discrete transistors. That's what the MOnSter 6502 project did. The only problem though is it can't run as fast as the actual chip due to signal delays and other factors.
