Speak & Spell looked like a giant calculator with a handle, and not many kids I know were lucky enough to have one bought for them. My parents obviously though it could help me and I was fooled into believing that education could be made fun. I was gutted when a friend dropped mine!
Speak & Spell was another electronic toy made by Texas Instruments and was a more refined version of Mattel's See & Say toy. Speak & Spell was the first in a series of toys like this, followed by Speak & Read and Speak & Math. I believe Texas also released a compact version of the Speak & Spell in the early-80s.
What I find bizarre is that the opening noise the Speak & Spell made when you turned it on has been picked up by a number of musicians and samples in their songs, such as Pet shop Boys. Depeche Mode even named their debut album Speak & Spell in honour of the toy! Speak & Spell also featured in the film ET as a communicator.
