Nothing else than a Touch & Tell with French voices stored in the Speech-ROM.
featured Le Livre Magique was manufactured September 1983 by Texas Instruments
in the United States and makes use of an interesting approach: The printed circuit board (PCB) is identical with the Touch
& Tell introduced one year earlier but lacks the Speech-ROM which is placed
in a small white module in the Expansion Port of the toy.
Consequently we located on the PCB of this early Le Livre Magique just two Integrated Circuits:
• CD8012: 4-bit
TMS1100 microcontroller with 2k Bytes ROM and 128*4 Bits RAM
• TMC0280/CD2802: TMS5110A VSP (Voice Synthesis Processor)
This module looks like the well known Expansion-ROMs of the original Touch &
Tell and uses one TMC0350 Voice
Synthesis Memory (VSM) introduced with the first version of the Speak &
Spell. It obviously stores the French voice of the Le Livre Magique.
• TMC0350/CDD62171: VSM (Voice Synthesis Memory) with 128k Bits capacity
Later models of the Le Livre
Magique include the same Speech-ROM on the Main-PCB.
The next evolution steps are the more advanced Le Super Livre Magique and the La Lecture Magique introducing two position sensitive keyboards in a foldable housing to accept small booklets.
Texas Instruments stopped the development of this educational line in 1993 with the cute Le Petit Ours Magique.
