Dismantling this Speak & Read manufactured in April 1986 by Texas Instruments in the United States reveals a design centered around four Integrated Circuits:
•
TMC0270/CD2705: 4-bit microcontroller with 2k*9 Bits ROM and 9*64 Bits RAM • TMC0280/CD2801: TMS5100 VSP (Voice Synthesis Processor) • TMC0350/CD2394, TMC0350/CD2395: TMS6100 VSM (Voice Synthesis Memory) with 128k Bits, each |
An inside view of some dismantled Speak & Spell products could be found here.
Few years later the Super Speak & Read with the position sensitive keyboard technology was introduced.
In 1986 we knew a total of 8 different plug-in modules for the Speak & Read, a comprehensive overview including the wordlists could be found here.
