TI-H: MIDI with SID chip




>Where do you get a SID chip or application information?

The SID chip was the chip that generated audio for the Commodore 64 and 
128. Comparable to Nintento or Gameboy sound, and very simple. I have a 
book with a whole section on it. I tried to find it, but It's at my moms 
house, so I'll have to pick it up. Jameco sells the 6581 SID, which is a 
12 volt version. I'll look to see if thereis a 5 volt only version. 
Otherwise, a DC/DC converter may be possible. I can guarante it'll draw 
some power, but for decent sound, I think a box may be nescesary. Also, 
something betwer must have come allong. The SID is just the model to go 
by. There may be newer ones too. We'll just have to see.
