Looks quite like the Litton 51 CDU we had in most of our DC-8-63s. A couple had Omega (pure crap), and I flew one or two that had Carousel INS. Loading the first 9 waypoints was the F/Os job, sometimes (actually quite often) the crossload of waypoints to the Left unit (remote) would not work so it had to be done all over again on that unit...
