After the fun of writing the Zombies game in Z80, I had a go at writing a version of Conway’s Life in Z80.

Life? What is Life?

Life is a type of program called a cellular automaton which is just a fancy way of saying it’s a simulation. In this simulation there are small units called cells, and each cell can be either alive or dead. Their state is dictated by a set of rules, and their neighbouring cells. The rules are really simple

  • A cell with 2 or 3 neighbours remains alive if it already is
  • A cell with 2 neighbours comes back alive if it’s dead
  • A cell with anything else dies off, or stays dead

From these simple rules you can get incredibly fascinating patterns, and it’s a great example of something called emergent behaviour
