I'm going to check the rest of the pins as far as the outputs go. What do you think the chances are that only those two pins are fried? If that were the case, I could work around that for now. What all does mach use?? In my case, wouldn't it be just 2-7, 10, 11, 15, and 18-25? I checked all of 18-25 against 10 and they all seemed to work (lighting up the LED's). I think I know how to check the outputs (2-7). But what about pins 1, 16, & 17. What role do they play, if any?
