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 Spanish talking El Loro Profesor was called Super Speak & Spell, too.

Dismantling this El Loro Profesor manufactured in March 1992 by Texas Instruments in the United States reveals a very well engineered printed circuit board (PCB) with three Integrated Circuits:

TSP50C42/CSM42031: 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/CMM19054: 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.

With the similar El Loro Parlanchin we know a second Spanish speaking Super Speak & Spell. Judging from the codes found on the Speech-ROM's the El Loro Profesor seems to be the successor of the El Loro Parlanchin.

A similar product was introduced in France with the La Super Dictée Magique and in Italy with the Grillo Parlante Piu.

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