Hi Dan,
Thanks for your response. I have a couple questions in regards to your answers:
When you say create a circuit do you mean in addition to the existing cartridge circuit board, like a daughter board? Is it possible to wire directly to the board (I am no EE which I am sure will become very clear.)
Yes, I was assuming a flip-flop would be the best way to go, that way I am not limited to just a LED, if I so choose I could use the binary switch to work as logic to turn on any other device (Every time a tank explodes, my toaster turns on).
Would it be as simple as adding to the existing code so that in addition to storing the collision data to it's normal memory locations it also stores it to the address my device is to monitor?
Thanks,
Mark
