This funny synthesizer based product from Texas Instruments generates a lot of different sounds and stores them into internal memory. Compared with earlier products of the Speak & line this one uses a quite simple technology.
This educational toy was rated by Texas Instruments for children aged between 3 and 5 years.
Dismantling this Little Maestro manufactured in December 1986 by Texas Instruments in the United States reveals a compact design centered around just two Integrated Circuits:
• TMP50C40/CM54128: TSP50C50 VSP (Voice Synthesis Processor) with 8-bit microcontroller and 8k Bytes Mask ROM for both program and voice and 32 Bytes RAM
• CF60034: Not yet discovered, probably a Port-Expander for the VSP
A similar product was introduced with the Speak & Music game.
