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.

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.
