Velko's builds

My Clock module worked fine (to be honest, I did not use it that much), but I have some new ideas to try out. Also, as I'm approaching the end of first stage of my build, the requirements for the Clock has changed. I could try to "patch" the existing module, but it's actually easier to re-build it on a new breadboard.   At first, however, I had to play around with Digital simulator, it might have been quite hard to iron out the details building hardware directly. Here's what I came up with: There's a lot is going on, I'll try to explain step by step.

I developed some demo programs using an assembly-like constructs in Python. All is nice and it utilizes real hardware for calculations. Still that is just Python code running on PC and sending control signals to my registers, ALU and memory. Eventually, I'll have to run the code on the 8-bit computer autonomously. For that I need to convert it to sequence of binary instruction opcodes and arguments - machine code. I've also tried to hand-assemble some simple programs, but it feels quite tedious and error-prone.

Looking at modules I have built so far, I realized that I have almost all I need for a complete computer. Long time ago I built Clock module and Program Counter . I've just updated Output module , There's ALU, 2 general-purpose registers, Flags register . Also I have RAM module and MAR register . I even have an Instruction Register. What's missing? Control Logic, of course!
