This
Speak & Music was sold in United Kingdom. The faceplate of the educational
toy differs from the original Speak & Music
sold in the United States of America.
It looks to us more like the German Music-Star.
Dismantling this Speak & Music manufactured in November 1986 by Texas Instruments in their Rieti, Italy facility for the British market reveals a compact design centered around just two Integrated Circuits:
|
• TMP50C40A/CD54149: TSP50C50 VSP (Voice Synthesis Processor) with 8-bit microcontroller and Mask ROM for both program and voice • CF60034: Not yet discovered |
