Complaints from consumers who had chosen to buy the Intellivision specifically on the promise of a "coming soon" personal-computer upgrade, eventually caught the attention of the Federal Trade Commission (FTC), who started investigating Mattel Electronics for fraud and false advertising. In mid-1982, the FTC ordered Mattel to pay a monthly fine (said to be $10,000) until the promised computer upgrade was in full retail distribution. To protect themselves from the ongoing fines, the Keyboard Component was officially canceled in August 1982 and the Entertainment Computer System (ECS) module offered up in its place. Part of Mattel's settlement with the FTC involved offering to buy back all of the existing Keyboard Components from customers. Mattel provided a full refund but without a receipt paid $550 for the Keyboard Component, $60 for the BASIC cartridge, and $30 for each cassette software. Any customer who opted to keep theirs was required to sign a waiver with the understanding that no more software would be written for the system and absolved Mattel of any future responsibility for technical support. They were also compensated with $1000 worth of Mattel Electronics products.
