Question: history of HP 41c tones

[d b]

One saturday back in '86 I assigned the ten notes on the PPC rom to wrap around the right side of my 41 and took it over to my bud Jordan's place. I thought it would impress him, being a piano player and all. He touched all the keys once, thought a bit, and busted out with a rousing version of “Mary Had A Little Lamb”. I turned out to be the impressed one. He told me that he'd have to think of a better song for it because it sort-of approximated three notes per octave like Chinese classical. Jordan sure knew a lot. The PPC ROM "telephone book" didn't even say that.
