60 year ago on this day Jack Kilby presented the fir integrated circuit.

10 years after that we could get hold of all those TTL chips. I built my digital clock with TTL chips and Nixie tubes.
12 years after that we had a calculator on a chip from TI and I built a calculator from a kit with it: http://www.vintagecalculators.com/html/advance-wireless_world.html
Another 4 years later we could get our hands on 8 bit micro-processors and we started dreaming up our own computer boards.
I have several calculators but the one I use all the time was made by Texas Instruments.
My first calculator was a TI-30, the first truly low-cost TI calculator. It became available the same year I started my electronics studies, perfect timing. Most of my co-students got one as well, except for a few with Casio calculators. But two or three years later I tried an RPN HP hand-held calculator, and since then it was only HP for me.
Am I showing my age
I bought my first sliderule when I was in my 30s because it was a device that always interested me. I actually keep it at my desk at work. Although I was born after the sliderule generation, I still learned how to use it and can do several functions with it.
Hard to believe it's only been 60 years, considering what we have nowadays in comparison. I started in electronics manufacturing at HP when I was 18 and at that time we were just beginning to see this crazy IC package called a BGA. That was 27 years ago.
I only use it to compute mileage when I fill up my old diesel Mercedes.

Having a sliderule - No... Knowing how to use it - Yes!

Then used slide rules in my Electronics course.
Calculators were those big desktop units made by Friden. Portable calculators hit the scene just after I finished my electronics course.
I worked with one of the first 40 DIP chips was ceramic with gold legs - a UART but not a bussed UART, but rather a standalone serial to parallel and a parallel to serial Chip. This was 1972-3.
At uni some had expensive HPs I only had a four function calculator with memory function. But I was often faster with it than the HP guys. I did my diploma thesis in physics and use big iron (IBM /370). I was one of the first to do the typesetting using the big machine.
I had my first ICs (TTL, 74xx) in the early 70ties, made my first PCB of course upside down.
In my case I was exposed to the first calculators, four-bangers and a scientific one around the early 1970s. Then when in high-school I also was exposed to my first ICs, (also TTL, 74xx) and linear ones. Oddly enough largely all made by TI.
Now an astonishing forty years later, I'm still using TTL stuff mostly from TI. And certainly Parallax gear, the BASIC Stamp. And as it happens I also was exposed to big iron, the IBM S/370 but in my early years in school, call it first to second and even third grade periods, for an experiment that IBM was doing. then years later a friend who's father was an IBM Research Fellow continued the process. Now? I still have one.
