 		 #169387 - it's not a big fly
Responding to: ???'s previous message
He probably should have Schottky clamps to Vcc and Gnd, at CON2 also, and a series resistor in the base to protect the base-emitter junctions, since they're apparently going to be driven through a cable. That's not at the core of his problem, though, is it?

You were right to mention that, though.
