The overall construction looks very similar to guidance equipment I worked with at Litton in the early '80s. We had all the ICs marked with our own part numbers, even if they were standard off the shelf military grade parts.
There is probably no existing record of what the parts actually are, unless maybe in a dusty file cabinet somewhere.
