MagiCard is a programming tool on a cartridge that originally came with a 100-page manual and was only available via mail order.[6] Video Life, an Atari 2600 implementation of Conway's Game of Life, was only offered to purchasers of MagiCard.[7] According to Gaines, 50 to 100 MagiCard cartridges were produced and less than 20 of Video Life.[2]
