how would one go about adding the CIVA INS or the ISG1 Smiths FMC to the 707?

Almost all you need to know about CIVA-INS and the 707: CIVA INS - THE ONLY THREAD PLEASE. And if you still have problems, feel free to ask questions. ;)

As for the ISG1 Smiths FMC, it has been mentioned several times, but I don't know who has done it, or how they did it. And seeing as I don't have it, I can't help you with it. Sorry.
