Hi;
Grant, I would Agree with you that the low for the Switches comes from the Run FF, But, He still shows a SHORT between the two pins. I just checked my board and I don't show ANY short, Both resistors show 1K each and between the pins on the Switch it reads 2K NOT 500 ohms. So when he brings them Low with the processor board in they both go low and output both go high, not one or the other. Without looking at the board I am only guessing what the problem is. I know that I don't have any other ideas !!
Thanks Marty
