SIC-1 is a programming game where the computer only understands a single instruction.
If you're ready for a challenge, respond to this job posting from SIC Systems:
SIC Systems is hiring engineers to produce highly efficient programs for our flagship product: the Single Instruction Computer Mark 1 (SIC-1).
The SIC-1 represents a transformational change in computing, reducing complexity to the point that the processor only executes a single instruction: subtract and branch if less than or equal to zero ("subleq").
Enter the brave new world of single-instruction computing and invent new ways of implementing programs that would be trivial on a conventional computer. Don't adjust the technology to match how you think, adjust your thinking to match how the SIC-1 operates!
- Learn an esoteric assembly language.
- Implement programs to unlock more impressive job titles.
- Optimize your programs to climb the leaderboards.
- Sacrifice your personal life for the good of the company!
