My Tron won't boot, and the problem is an inoperative reset circuit. It was working a couple of weeks ago, and now does not. The purple wire does not go from low to high on boot. If I ground the base of the last transistor in the reset circuit, the output is pulled high by the pull-up resistor, and the board boots fine. I tried shotgunning the LM3900 since I had one laying around, but no change. I also checked all the resistors and diodes in the reset circuit.
Anyone know the most common cause of reset circuit failures besides the LM3900? (and please don't tell me to cut the purple wire
