RSL-1

RSL-1 is a package containing a graphic pattern drawing routine and an implementation of The Game of Life. In the game of life patterns evolve using the following rules:

• Any live cell with fewer than two live neighbours dies, as if caused by under-population.
• Any live cell with two or three live neighbours lives on to the next generation.
• Any live cell with more than three live neighbours dies, as if by overcrowding.
• Any dead cell with exactly three live neighbours becomes a live cell, as if by reproduction.

The programs use machine language rather than BASIC, making their drawing routines much faster than most other versions available at the time.
