If it weren’t for the TMC0281, E.T. would’ve never been able to “phone home.” That’s because the TMC0281, the first single-chip speech synthesizer, was the heart (or should we say the mouth?) of Texas Instruments’ Speak & Spell learning toy. In the Steven Spielberg movie, the flat-headed alien uses it to build his interplanetary communicator. (For the record, E.T. also uses a coat hanger, a coffee can, and a circular saw.)
