A mini-computer you run from a folder on your computer that can train small LLMS

Hey everyone, Most people build 8-bit computers to run Pong or Tetris. I wanted to see if I could push a custom 8-bit architecture to do something much harder: train a neural network from scratch. I built VirtualPC, an open-source 8-bit computer system simulated from basic NAND gates up to a functional CPU that can train a small neural net from a folder on your computer. Repository: https://github.com/ninjahawk/VirtualPC › The ML Core Instead of importing PyTorch, everything happens at the bare-metal assembly level: Custom ISA: The Instruction Set Architecture was designed to handle the math needed for machine learning. Low-Level Training: The CPU executes forward and backward passes directly through custom assembly code. Matrix Math on 8-bit: Overcoming severe memory limits using disk-backed memory swapping to store weights. › The Architecture Python-Based VM: Runs the entire simulated hardware environment. Custom Assembler: Translates raw assembly files into machine code binary. Full Stack OS: Handles basic I/O and memory management from the ground up. Building this taught me exactly how machine learning math translates into physical CPU cycles. The project is completely open-source and free to mess around with.
