NAND-Budget Tracker
CSA-101 §11.6. Your running count of NAND-equivalent gates as you build the 6502 from sand. Source-of-truth for the CSA-101 spark-and-keep-it-burning thread.
Why this exists
A 6502 is about 3,500 NAND-equivalent gates. That number is small enough to count and big enough to feel.
Each CSA-101 week, you build a piece: four gate compositions in Week 2, a 4-bit adder in Week 3, an 8-bit register in
Week 4, then read Arlet's Verilog core in Week 7 and synthesize the whole chip onto your Tang Primer 25K in Week 8.
This page ticks the running counter every time you ship a lab. The progress bar is a single visual answer to the Week-1 question every student asks: am I actually building a CPU, or am I just doing exercises that feel like they could become a CPU? Tick the row and watch the count climb. Same numbers your instructor sees.
Local-only: your progress is stored in your browser. Clear it with the toolbar button. No account, no upload.
Tick a week below as you finish its lab. The bar grows toward the 6502.
