SIC-1
Write assembly for a computer that has only one instruction
SIC-1 gives you a computer that understands only one instruction: subtract and branch if the result is less than or equal to zero. Using only that instruction, you write assembly programs that solve tasks. Each solved task earns you a promotion at a made-up company, and the story pokes fun at overwork and corporate culture.
