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:

Product line	Original product	Compact edition
SPELL	Speak & Spell	Speak & Spell Compact
MATH	Speak & Math	Les Maths Magiques

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.

Dismantling the Les Maths Magiques reveals indeed the technology of the Speak & Math / Speak & Spell products.

The printed circuit board (PCB) of the educational toy sports well-known components:

	CP3447 - A customized TMS1000 single-chip microcomputer
	CD2801A - The TMC0281 Voice Synthesis Processors
	CD62173 - The TMC0350 Voice Synthesis Memory
