I have 2 vintage calculators. One is a Texas SR50 scientific which I bought in my first year of university, 1975. It was expensive (ISTR £47) but worth every penny. The other is the famous HP35, daddy of pcoket scientific calcs which I picked up for a nominal amount at Harpenden many years ago. A gorgeous bit of engineering. HP's reverse polish logic always made perfect sense to me.
My daily use calc, a Texas TI-36X solar powered scientific/engineering, is quite vintage now. Mine looks like the 1993 version: https://en.wikipedia.org/wiki/TI-36
