Narrative:

No idea why it occurred; but apparently there was a previous occurrence with this a/C. Soon after raising gear on departure; got 'GPS primary lost' on first officer's FMC. Checking pages we found we had lost #2 ir. I gave control of the aircraft to the first officer and proceeded to check and attempt to accomplish QRH procedures. Never got an indication of anything wrong on the overhead panel. While I was 'in the books;' the aircraft's instrumentation downgraded rapidly. We lost flight directors; autothrust; and autopilots. Not sure of the exact sequence of downgrade; but it all happened relatively quickly. Requested to level off at a lower than cleared altitude with center and then contacted dispatch with the problem. There was no doubt in my mind we weren't taking this airplane out over water; just wanted to know if he wanted us back at our departure airport or somewhere else. Dispatch's first said go to option 1. I had to tell him their long runway was closed and we were still 5-6000 pounds overweight no matter what the right/west. Airport 2 was next and best with over 9000 ft. Meanwhile; I'm talking and typing and reading as fast as I can; the first officer had lost everything. We were in alternate law. The left side still showed some partial displays. In fact; at one point the left side flight director came back; but for less than a minute. Now diverting with approach; the first officer was getting all his heading; and altitude by reading across the cockpit. Had to request a 360 to get lower and be stabilized because as soon as the gear went down we were in direct law. The first officer flew it to an uneventful overweight landing. Talking to maintenance after parking; they asked when we lost #3 ir. We never got any indication we had other than all the downgrading of systems. We then waited a couple of hours for a scheduled overnighter to arrive; took that and proceeded on to our desination. I feel too much of my time and energy was spent responding to messages from dispatch. There should be an abbreviated way to relay everything.
