This is a first step towards completing the board. The odd part is that one of the ICs is soldered on the bottom side. This was a clever thought Collin had as it reduces bridges to 5 total from at least 15. As I realized yesterday, I had put no values to most of the components, so tonight, an updated version of the board will be placed online with the values written.
Not all R2R resistors are in place as I ran out of them. So it might be finished tonight. The thing is that soldering resistor ladders is SOOOO BOOOOORRIIINNGGGG!! I should have used a resistor array.
