SIC-1 (itch)

You have been contracted by SIC Systems to produce highly efficient programs for their 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 discover 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!
