Think
about a Speak & Math without the fluorescent display trimmed to German language.
A slightly more powerful version was sold in other countries with the:
 | le Calcul magique |
| Dotto Conta-Parla |
| Maths marvel |
Dismantling the Mathe-Fix reveals a small surprise, the
printed circuit board (PCB) of the educational toy is centered around a TMS50C40
standard voice synthesizer
chip. We know this technology already from the Little Maestro
and its sibblings Speak & Music, La Musique Magique
and Fonillo Suonaparla.
