Описание: 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:    • Rare LED watch chip from Texas Instruments...
And I eventually repaired all my HP clock modules in an epic repair-a-thon:    • HP 98035 Clock Module Repair-a-thon
