This Speak & Math model from the year 1986 got a slightly changed keyboard design. View the original Speak & Math here.

Other products in the Speak & line cover spelling and reading words. Compare this Speak & Math with both Speak & Spell and Speak & Read. A compact version without display was sold in France (le Calcul magique) and Germany (Mathe-Fix). 

Dont't miss the appearance of the Speak & Spell in the movie E.T. - The Extra-Terrestrial. Do you know Qubais Reed Ghazala ? Get more tunes from your Speak & Math with circuit-bending.
