I needed a rare clock chip used in a 1970's Texas Instrument watch to repair a piece of vintage HP equipment. I could only find one from some Chinese vendors. But the chip swap did not repair the thing. Did I get a real or a fake chip? Only one way to find out: look inside.
I have since managed to reverse engineer the chips make them work, see here: https://youtu.be/pr6HTiWrMmk
And I eventually repaired all my HP clock modules in an epic repair-a-thon: https://youtube.com/playlist?list=PL-_93BVApb5_e9h-vqKn1FPUg9WnzFL20
