How to do the legs

The DIP row spacing is actually 725 mils not 700. It makes it annoying to solder because the rows don't line up exactly with the rows in a breadboard, but it's not an error.
Using a set of single row socket headers in the breadboard, or even two stacked, allows the socket headers to spread a little and make it easier to hold the pins and pcb for soldering, and the finished soldered pins aren't pinched inwards too badly.
