A Go-based simulator of the 16-bit CPU described in 'But How Do It Know?' by J. Clark Scott, built from NAND gates up through registers, RAM, ALU, and control unit. It includes an assembler, a graphical display, and I/O support, making it a fully functional educational machine.
Use cases
- simulate a CPU built from logic gates
- learn how CPUs work at the gate level
- write and run assembly programs on a simple 16-bit machine
- study computer architecture concepts like ALU and control unit
- visualize CPU execution with a screen output
- teach low-level computing fundamentals
When to choose
- you want to understand CPU internals from NAND gates upward
- you're following the 'But How Do It Know?' book and want a working model
- you need an educational, hackable CPU simulator in Go
- you want to experiment with assembly on a minimal architecture
When to avoid
- you need a production-grade or performant CPU emulator
- you require modern CPU features like interrupts, stacks, or floating point
- you want to simulate a real-world commercial processor
- you need a general-purpose virtual machine for running real software
