Mattel Intellivision’s Mystery Keyboard
Unveiled by toy manufacturer Mattel in 1979, the Intellivision got cute by combining the words "intelligent" and "television," and then claimed to have better graphics than its main competitor, the Atari 2600.
But it’s what Intellivision didn’t come with that made it infamous: a keyboard. That missing component, featured in commercials but not packaged with the system, promised to increase the Intellivision’s computing capabilities, turning it from a game console into a home computer.
But manufacture of the keyboard was delayed so often that even the Federal Trade Commission started fining Mattel. Eventually, 4,000 keyboards were produced, but by then the whole project was canceled and both the world and Mattel had moved on.
