Ha, I'm not surprised. Boeing basically owns everything about the E-3, including the software. I guess technically the 4Pi is an IBM creation, but still, it's mostly a Boeing thing. Fun fact: An E-3 takes around 3 times as long to get off the ground as a typical modern airliner. It's a bit disconcerting the first time you experience it. The 707 is really, really old. And as I recall, it's somewhat normal for an E-3 to be loaded to over max takeoff weight during normal operation. But my experience is 25 years out of date, so maybe that's changed. Isn't the USAF just about the only organization still operating 707 in any capacity? KC-135 (sorta), E-3, what else? I think the KC-135 at least got re-engined, that probably helps a bunch.
