Let's Build a Computer!
summary
Starts from a single nand gate and shows every concrete step to a running machine: build NOT/AND/OR/XOR (XOR optimized from nine nands down to four), 16-bit registers, adders and a carry-lookahead design to drop depth from linear to logarithmic, a full 16-bit ALU (same style ALU done in ~440 nands by a forum contributor), RAM/ROM/screen/keyboard wiring, a CPU and memory-mapped I/O, assembler, VM, compiler and an OS with games — the 12-week Nand to Tetris curriculum actually produces a working simulated computer.
