Nothing else than a Touch & Tell with Italian voices stored in the Speech-ROM.

The Libro Parlante was distributed in the 80s like some other Texas Instruments products by Clementoni

LibroParlante_PCB.jpg (108105 Byte)The featured Libro Parlante was manufactured already in October 1982 by Texas Instruments om their Rieti, Italy facility 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 Libro Parlante 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 Italian voice of the Libro Parlante.

Module:

TMC0350/CDD62176: VSM (Voice Synthesis Memory) with 128k Bits capacity

Later models of the Libro Parlante include the same Speech-ROM on the main printed circuit board (PCB).

The next evolution step is the more advanced SuperLibro Parlante.
