funny synthesizer based product from Texas Instruments generates a lot of
different sounds and stores them into an internal memory to replay. Compared with earlier
products of the Speak & line this one uses a quite simple technology.
This educational toy introduced in 1988 is very similar to the Speak & Music introduced already in 1986 but uses a German speaking language. Don't miss the Speak & Music sold in United Kingdom, with the La Musique Magique a French speaking version and the Italian speaking Fonillo Suonaparla.
Dismantling this Music-Star manufactured in August 1988 by Texas Instruments in the United
States for the German speaking market reveals a small surprise - the printed
circuit board (PCB) is different from its International siblings. The original
two-chip design with a TMS50C40 Voice Synthesis Processor and CF60034 was
replaced with a single-chip solution.
The single-sided PCB of this Music-Star sports just one Integrated Circuit:
|• TMS50C43/CD57303: TSP50C50 VSP (Voice Synthesis Processor) with 8-bit microcontroller and 16k Bytes Mask ROM for both program and voice and 128 Bytes + 16 Nibbles RAM|
Comparing the short-lived TMS50C40(A) introduced in 1986 and its successors from the TMS50C4X Series introduced in 1987 show a few differences including a more flexible I/O Port structure of the latter parts. We assume that the CF60034 is a simple Port-Expander for the TMS50C40 to sample the keyboard of the toys.
Don't miss a very early Prototype of the Music-Star with a very unusual internal design.
A total of 12 well-known German children songs are stored inside the memory toy:
|• Ihr Kinderlein, kommet
• Was soll das bedeuten
• Ich geh mit meiner Laterne
• Fuchs, Du hast die Gans gestohlen
• Weisst Du, wieviel Sternlein stehen
• Wer will fleissige Handwerker sehen
• Es tanzt ein Bi-Ba-Butzemann
• Ein Männlein steht im Walde
• Es war eine Mutter
• Alle Vögel sind schon da
• Im Märzen der Bauer
• Winter, ade!
Other products in the Speak & line cover spelling and reading words. Compare this Music-Star with Speak & Math, Speak & Spell and Speak & Read.
