At first glance this rare Les Maths Magiques sold in France seems to be a variation of the Speak & Spell Compact and its sibbling Speak & Write.
But the keyboards of these two products type the characters "A"..."Z" while the Les Maths Magiques reads the numbers "0"..."9" like the original Speak & Math introduced already in 1980.
If you compare the keyboard with the later Maths marvel and its sibblings le Calcul magique, Dotto Contaparla and Mathe-Fix you solve the mystery:
|Actually we discovered the the unknown "Speak
& Math Compact" sandwiched between the original Speak &
Math and the le Calcul magique introduced in
1986 and using much simpler technology.
