[sdiy] CMOS Saw to Tri Converter

This one is not a suboctave, rather it runs at 1F.

Same conditions as the suboctave converter: imperfections
in the saw input will show up in the output.

But again, it sounds far more like a sine than the original
saw input.

Also, my drawing doesn't show the interal wiring of the 
4007 MOSFETs exactly as it is in the chip.  The pin numbers
tell the real story.  Only the 2 P transistors are used.
There is one free inverter left on the 4007 package.  All
unspecified input pins are grounded.  All gates on the 4069 
are used.
