Rare LED watch chip from Texas Instruments (HP 98035 Repair-a-thon Part 0)

What about checking it by making a retro LED watch out of it? Head over to Patreon for the better, but demonetized version of this video... Edit: I eventually made a bubble LED hack watch out of it:    • Bubble LED clock hack with 1970's tech   Music Credits: Ether Disco by Kevin MacLeod Link: https://incompetech.filmmusic.io/song...
