Wow thanks for this Jonathan, i had no idea the sounds was created by the border!?!? Is there anything else we can learn about how to generate different sounds?

Yes, the lowest 3 bits of port 254 are used to set the border but other bits toggle the loudspeaker and control the ear and mic ports. The faster you toggle the speaker bit the higher the pitch of the sound generated.
