DATAMATH  CALCULATOR  MUSEUM

The first edition of the Libro Parlante
makes use of a small module

Inside the module we discover with the
TMC0350 (CD62176) a Speech-ROM

The printed circuit board (PCB) of the first Libro Parlante lacks the Speech-ROM but is 
otherwise identical with the original Touch & Tell introduced one year earlier.

The final edition of the Libro Parlante includes the CD62176 Speech-ROM
on the main printed circuit board (PCB).
