|This is not a game, but a programming tool for the Atari 2600. It was probably only available via mail order, and the label is a simple white paper with some typed text that says MagiCard and either CommaVid or "Computer Magic", which was CommaVidís original name. The cartridge also came with a 100+ page manual, and no box.
The MagiCard manual includes five sample programs you can type in to demonstrate how the MagiCard works. To save you the trouble of having to enter these programs, we've gathered together five ready-to-run binaries so you can try them out in an emulator or Cuttle Cart. You can download these sample programs here.
