From the beginning, Mattel attempted to distinguish the Intellivision from the Atari 2600 by stressing that the Intellivision wasn't just a toy -- it was going to be the basis of a home computer system. Slipping the Master Component into the Keyboard Component would unlock the full power of the 16-bit microprocessor in the Intellivision.

The Keyboard Component contained 16K of shared dynamic RAM and its own 6502 processor to handle I/O functions. Special programs were available on cassettes. The built-in tape deck featured a sophisticated block-addressable cassette interface; an audio track could be synchronized with a program and its graphics. With the provided microphone, parts of the audio track could be re-recorded and played back under program control. A cartridge port allowed standard Intellivision games to be played without removing the Master Component, and a printer port allowed output to a 40-column thermal printer.

The Keyboard Component (code named the Blue Whale, occasionally referred to as the Intelliputer) was developed by Dave Chandler's engineering group, the same group that did the final engineering on the Intellivision itself. The Keyboard was certainly an impressive piece of work, but, from a marketing standpoint, was hopelessly impractical; there was no way to produce it for a reasonable selling price. If it hadn't been for Dave "Papa Intellivision" Chandler's reputation, the project probably would have been killed off early on. Instead, his group was allowed to continue tinkering, trying to bring the cost down. Scheduled to be available in 1981, the Keyboard's release was delayed time and time again.

When Jay Leno entertained at the Mattel Electronics 1981 Christmas Party, he did his homework; he got his biggest laugh with the line: "You know what the three big lies are, don't you? 'The check is in the mail,' 'I'll still respect you in the morning,' and 'the Keyboard will be out in the spring.'"

Consumers weren't laughing, though. Complaints from people who bought the Intellivision specifically because it could be upgraded to a computer caught the attention of the Federal Trade Commission, who started investigating Mattel for fraud. Mattel insisted that the Keyboard was a real product that was still being test marketed; a trickle of Keyboard Components was made available to selected stores and offered by mail to consumers who complained (at a loss to the company). The thermal printer was only available mail order; this was apparently the same printer (except for the nameplate) that later received somewhat wider release as part of the Aquarius system. Several programs on cassettes were available; some (Conversational FrenchJack LaLanne's Physical ConditioningSpelling ChallengeJeane Dixon Astrology) were programmed in 1610 assembly language and took full advantage of the Intellivision system sound and graphics, others were more limited BASIC programs (Geography ChallengeFamily BudgetingCrosswords I, II & III) that required a BASIC cartridge to be plugged into the game port. With the BASIC cartridge, the user could also write his or her own programs.

Finally, in mid-1982, the FTC ordered Mattel to pay a monthly fine (said to be $10,000) until the Keyboard was in wide distribution. Mattel was forced to go with its back-up plan: it released instead the Entertainment Computer System (ECS) that had been quietly developed by a different division. Although less powerful than the Keyboard Component, it minimally offered what had originally been promised: to turn the Intellivision into a computer. It was sufficient (along with an offer to buy back all outstanding Keyboards) to get the FTC off Mattel's back.

The Intellivision Keyboard Component, with only 4,000 produced, was officially canceled.

But it didn't go quietly: Compro, Inc., the Costa Mesa, California company that had been contracted to manufacture the Keyboard, sued Mattel for ten million dollars, claiming breach of contract, fraud, and nonpayment for the last 1,300 units. This was just one of the lawsuits Mattel, Inc. settled early in 1984 when Mattel Electronics was closed.

(For its part, Compro was fed up with the videogame industry. Once a major supplier to Atari, Sega, and Commodore as well as Mattel, they got out of the business. Today, under the name Mexmil, they manufacture insulation for McDonnell Douglas and Boeing aircraft. When asked what happened to all the videogame and computer manufacturing equipment, an employee said "I think they sold all that stuff to Nintendo.")

FUN FACT: All the money spent on the Keyboard Component didn't go totally to waste; as the ranks of the programmers swelled during 1982, development systems could not be assembled fast enough. The bottleneck was the hand-built Magus board -- the interface between the development computer and the Intellivision. Then some bright person realized that a Blue Whale would make a dandy development system! A slightly modified Keyboard Component (dubbed a Black Whale) would accept the compiled object code for a game serially to its internal RAM; that RAM, mapped to the same addresses as an Intellivision cartridge, would be read by the attached Master Component as if it were a cartridge.

While slower to download a game than a Magus board (which read data from the computer over parallel lines), the Black Whale proved to be a quick, cheap solution. By the middle of 1983, half of the development systems in Hawthorne and all of the development systems at Mattel Electronics France used Black Whales.
