MagiCard is a programming cartridge for the Atari 2600 released by CommaVid in 1983. It provides a simple on-screen editor that lets owners type in BASIC-like code to create custom programs, including five sample demos. The cartridge also unlocks the mail-order exclusive game Video Life, a cellular-automaton version of Conway's Game of Life. Notable for being the rarest officially released 2600 title, MagiCard serves both as a hobbyist development tool and a gateway to a unique hidden game.
