# 🖥️ Exploring My Custom 8-bit Computer

In this video, I walk you through how my custom-built 8-bit computer works. From fetching instructions to executing binary addition, you’ll get a clear view of how simple components like RAM, registers, and the ALU come together to perform operations. 

I've used hex input to simplify binary data input and explain every step of the process. Watch till the end to see the final result displayed on my 3-digit display!
