I'm thinking about building an 8-bit CPU with four 256 RAM systems. I'm planning to use breadboards and NPN/PNP transistors to make it happen. I could really use some advice, especially when it comes to assembly language for this project. I also intend to open source the design once it's done.

Starting with software simulation is a good idea! It lets you test out your design before you dive into the FPGA development or raw transistor setup. There are some great tools out there, like Logisim, that can help with this step. Take it inch by inch instead of trying to rush into hardware right away!

What software should I use for the simulation?
