Hello,
Back in the 80's I was a very happy teenager in Mexico when I got a C128 and I remember being very impressed by a demo of the computer.
I can't remember if it was a C64 demo or a C128 demo but I am almost 100% sure the floppy disk was included in the computer box.
Here is all I remember:
The demo displayed a radio-k7 player on the ground and the sound was a known classical music prelude or sonata.
As the music played, black music notes came out of the player and started floating upwards in the air.
The bottom part of the screen was a yellow ground and the upper part was a blue sky with maybe white clouds
I really hope my bare description is enough for someone to recognise that demo. I am very interested in finding it and I thank you in advance.
Best regards
girazu
