Speak & Spell Simulator

The Speak & Spell was an electronic toy consisting of a speech synthesizer and a keyboard. It was produced by Texas Instruments and introduced at the summer Consumer Electronics Show in June 1978.
A whole generation of kids learned to spell on this cheery orange device with alphabet keys and a hardy handle. Speak & Spell contained a single-chip speech synthesizer, a disrupting innovation for the time, and a robotic voice that encouraged children to spell more than 200 common words.

I dreamed of this toy but my parents never got me one. I can finally play with one from this page.
