Here - 1000 BiT

CAREFUL! The numbers after the POKE must be exactly right! If not, you may mess upthe computer's temporary memory when you run the program. This will not harm thecomputer, but you would have to turn the computer off, then on again, and would losethe program you have in memory.Run it. You should hear the "orchestra tuning pitch" middle A. If you do not hear asound, first check that the TV is turned up loud. Then check that EVERY number in theprogram is correct.BUT HEAVENS, SO MUCH WORK FOR ONLY ONE NOTE?Yes! It takes five POKES to set up the sound chip (lines 20, 22, 24 and 26). It takes onemore POKE to turn on the sound (line 30) and two to turn it off again (lines 90 and 91).But notes are cheaper by the dozen. You can make more notes, even a whole song, withonly two more POKEs per note and, in fact, if you do it in a loop and use DATA, it isalmost easy.Let's explore the SID chip some more.110
