Nobody has ever really measured and documented all the inputs and outputs that I can recall. It might be helpful to better understand these devices in the hopes of fixing a few every now and again. Seeing what the PWM is doing along with the discrete inputs and outputs is fairly simple to measure and document. Decoding the serial line would be a little more interesting. For instance - what does the chuff input from pin 17 spit out to the serial line when triggered?
I have no real interest in emulating the R2LC for commercial purposes, that could be a challenge for someone else of a more entrepreneurial spirit.
