A colleague of mine at work just purchased a working vintage Texas Instruments scientific LED calculator, I believe the first use of LEDs in a calculator available for purchase in the early 70s, just like the one he had in high school/college back in the day.
I was telling him the X1/9 came from the factory with a LED clock long before some people knew what LEDs were. What model year was the first use of that LED clock?
