Yamaha TYU-30 Fun-Keyboard (polyphonic squarewave toy keyboard with key lighting)

This small squarewave toy keyboard has only 1 main voice sound (piano) and 4 rhythms, but it has a key lighting function to learn keyboard playing. Like the Yamaha PC-100 not the keys itself but a row of small LEDs above them light up, but instead of fragile PlayCards the musics are stored on ROM cartridges now.

main features:


The manual I downloaded from Yamaha claims that this instrument originally came with 2 music cartridges, but mine (from flea market) has only the "CARTRIDGE A" with 10 nicely composed melodies:

cartridge A

  1. Frère Jaque
  2. Londonderry Air
  3. I've Been Working On The Railroad
  4. Aloha Oe
  5. Beautiful Dreamer
  6. Little Brown Jug
  7. Chopin's Nocturne
  8. On The Beautiful Blue Danube
  9. Twinkle Twinkle Little Star
  10. Auld Lang Syne
cartridge B (I don't own this, thanks to The Reverse Engineers for the info.)
  1. Oh Susanna
  2. La Paloma
  3. Michael, row your boat ashore
  4. Cielito Lindo
  5. When the saints go marching in
  6. Brahm' Cradle Song
  7. Bach's Minuet
  8. Ode to Joy
  9. Jingle Bells
  10. Silent Night
To play keyboard, select the "rhythm play" mode. The others are for the built-in musics and key lighting. It took me quite long to understand why the thing often had refused to play them and other times didn't, until I read in the manual that to get the musics to play, you must first press the key with the melody number and while still holding that key press and release the "start/ stop" button. (Sorry, previously even me explained this wrongly.) This reminds me much of  my Atari 8 bit homecomputer reset button sequence for cassette loading, but for operating a children toy this is really a little hard and rather resembles the procedure for unlocking the child lock function of a badly designed VCR.

Direct sucessor of this instrument was the Yamaha TYU-40.
