This wonderful hybrid uses the housing of the original Speak & Spell from 1980 with the modern electronics of the first Super Speak & Spell

The English speaking sibling of this Italian talking Grillo Parlante Piu was called Super Speak & Spell, too. In France we know the La Super Dictée Magique and in Italy the Grillo Parlante Piu. With the El Loro Parlanchin and El Loro Profesor two Spanish versions were introduced.

Tired of the blue line? Believe it or not, customers in China enjoyed already in 1990 their own "Professor" in bright red colors.

Dismantling this Grillo Parlante Piu manufactured in April 1991 by Texas Instruments in the United States reveals a clean design centered around just three Integrated Circuits:

TSP50C42/CSM42030: TSP50C50 VSP (Voice Synthesis Processor) with 8-bit microcontroller and 8k Bytes Mask ROM for both program and voice and 128 Bytes + 16 Nibbles RAM
TSP60C19/CMM19035: VSM (Voice Synthesis Memory) with 256k Bits
Hitachi HD44780: LCD Controller for monochrome dot matrix liquid crystal display with 8-bit Interface

The main differences between the different Super Speak & Spell siblings are the Speech-ROMs:

La Super Dictée Magique: TSP50C42/CSM42027, CMM19031
Grillo Parlante Piu: TSP50C42/CSM42030, CMM19035
El Loro Parlanchin: TSP50C42/CSM42031, CMM19036
Super Speak & Spell (91): TSP50C42/CSM42030, CMM19048
El Loro Profesor: TSP50C42/CSM42031, CMM19054

The toy is intended for players ages 6 to 11.
