The Music-Star educational toy was introduced in 1988 for the German market, about two years after the English speaking original Speak & Music and its International siblings La Musique Magique (French Voice), Fonillo Suonaparla (Italian Voice) and Speak & Music (British Voice). It is based product on Texas Instruments' speech synthesizer technology and generates a lot of different sounds and stores them into an internal memory to replay.
Dismantling this early Music-Star prototype manufactured in
December 1987 88 by Texas Instruments in the United
States for the German Marketing Department in Freising near Munich reveals a
big surprise - it uses two printed circuit boards (PCBs) crammed into the
The Main-PCB looks very familiar to us, it is actually from the original Speak & Music with both the TMS50C40/CM54129 Voice Synthesis Processor (VSP) and CF60034 Port-Extender not populated and wired directly to the second PCB.
The second PCB with rather unusual looking Integrated Circuits (ICs) is labeled "50C42 Emulator" and sports some small switches and a large but unused connector.
The 50C42 Emulator PCB and uses two ICs:
• TSE50C4X-1GB: TSP50C4X Bond-Out VSP (Voice Synthesis Processor) with 8-bit microcontroller and
external ROM for both program and voice and 128 Bytes + 16 Nibbles RAM in a large PGA housing
• TMS27C128: EPROM (Erasable Programmable ROM) with 16k Bytes capacity in a ceramic package
Comparing the short-lived TMS50C40(A) introduced in 1986 and its successors from the TMS50C4X Series introduced in 1987 shows quite a few differences including a more flexible I/O Port structure of the latter parts. We assume that the CF60034 used with the Speak & Music and its siblings is a simple Port-Expander for the TMS50C40 to sample the keyboard of the toys.
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.
