Mattel Electronics already had a "plan B" in progress. Increasingly concerned that the Keyboard Component division might never actually produce a sellable product, in mid-1981 Mattel Electronics' management set up a competing internal engineering team headed by Richard Chang. Ostensibly, this group was working on a low-cost add-on called the BASIC Development System, or BDS, which would be sold as an educational device to introduce kids to the concepts of computer programming via a simplified color-coded BASIC interpreter and an inexpensive keyboard. Only a few people within Mattel knew the team's "real" mission: to either fix the Keyboard Component, or replace it.
