Xhosa, thanks for the info.
I'd like to know what the chip was used for and by whom?
Does anyone have a clue?

Yeah the "03640" is the CAGE code for IBM Federal Systems Division (they built the space shuttle's main computer, along with a bunch of other stuff) which is now Lockheed Martin as John said. Besides that, no idea, I looked up the part number (153A757) on aerospace parts supplier websites, which will sometimes get you an end-use application or equipment name, but no results this time.
Great photos though, what a nice chip!
