The docs are now online. I missed shipping today, I won't miss tomorrow. If you have any questions hold 'em for a day or two if you don't mind. I need a little breathing room. The deal was I would cut cost by just doing docs online. However if you ordered a pcb and can't print the docs out I'll send you a short paper copy. http://www.mindspring.com/~vco/vco4/vco4.html -tg
