We NEED to use the 8580, since the calc runs on 5v. The other chip is 
12v, and would be dificult. You'd need two 9v batteries just to run it! 

Also, how dificult would 1 or more MAX 038 chips be to interface? That's 
a VERY common Waveform generator. I also saw some others. The AY-3-8910 
Programible sound Generator with 2 8-bit I/O ports. What's this???
