Historic programs from the 1980s

This archive contains old programs that I wrote together with my friend Arne Erik Toepper in the 1980s. The programs were developed in Turbo Pascal 3.0 for MS-DOS and are available here both as source code and as interactive browser versions.

Wa-Tor 2.12 – Ecosystem Simulation (1985)

Wa-Tor is a toroidal water world inhabited by two species: fish and sharks. The simulation models a simple ecosystem based on the predator-prey principle. Fish feed on unlimited plankton, while sharks hunt fish. The world is displayed as a 32×14 torus grid — anything leaving one edge reappears on the opposite side.
