I have been working on a VCO PCB lately and have put a picture,
schematic, and some text on the web at:

It is the saw/pulse design with triangle added, uses a matched
transistor pair and tempco resistor in the expo converter, and has PWM,
linear FM, and hard sync inputs.

I would like to do a small production run of the board if enough people
are interested so please let me know if you might want one.  Production
boards would be solder masked with a silkscreened legend. They would be
about $16 U.S. each.
