A real instruction set where every card is one instruction. ♠ arithmetic · ♥ memory · ♦ control/output · ♣ logic — the suit is the op family, the rank is the operation. Deal a hand of cards, run it on a real stack machine, watch it compute. The card-notation an AI reached for, made to actually execute.
| Suit | Family | Ranks → operations |
|---|---|---|
| ♠ | ARITH | A–10 = push that number · J = add · Q = subtract · K = multiply |
| ♥ | MEMORY | A = load top→ACC · 2 = push ACC · 3–6 = store top→R0..R3 · 7–10 = push R0..R3 · J = dup · Q = swap · K = drop |
| ♦ | CONTROL | A = print top (number) · 2 = print top (as character) · K = halt |
| ♣ | LOGIC | A = equal? · 2 = greater? · 3 = and · 4 = or · 5 = not (each pushes 1/0) |
How it runs: a stack machine. Number-cards push values; operation-cards pop values, compute, and push results. 5♠ 3♠ J♠ means "push 5, push 3, add" → stack holds 8. Then A♦ prints the top. It's Reverse-Polish (the operation comes after its operands), the same way real stack machines and old HP calculators work.
