I got some rest and I am revisiting the stable oscillator calculation, using low quality x87 FSIN instruction and higher quality gcc sin(x) problem to verify the correct answer of what the apparent frequency error is in the calculation, due to numerical error in x87 FSIN instruction. For the oscillator example, all results I've obtained thus far should be treated as suspect. I was trying to do it in a rush. -- KM
