Magnavox boasted that Odyssey 2 had "the mind of a computer," and Computer Intro was their way of proving it. Allowing users to program in Assembler language, Computer Intro included a spiral-bound guide providing basic fundamentals and sample code for creating simple games. The guide was invaluable to the aspiring programmer in 1979, with its overview of computer history, decimal-binary-hexadecimal charts, instruction sets, and a solid glossary. This cartridge, when combined with the Odyssey 2 keyboard, turned the console into a reasonable facsimile of a personal computer when real PCs were not yet commonplace.
