New turnout control boards

Today I began to replace the last five of my NCE Switch8's with the new version or Mark2. Works the same way but WAY easier to program and allows you to provide a separate D.C. power source for the switch machines. The boards' controls are powered by a separate booster from my NCE system. This allows me to turn a switch even if the main track is shorted out. Handy. And because I am powering many switches, having the separate D.C. Power source means that there is more power left for the trains. So I programmed the boards and am now installing them under the train. This all has been delayed as my wife and I traveled most of June. Someone has to do it!
