Calculator related magazines / journals

[EugeneNine]

Those look more to be computer magazines than calculator magazines though I realize the lines are blurred some when a calculator has as much computing power as those early computers.

If your going that route then ones like https://archive.org/details/byte-magazine apply.
maybe some of the ones like https://archive.org/details/ednmagazine

radio electronics and popular electronics had calculator articles IIRC

It was popular electronics IIRC that I read about the HP28 and later 48 which led me to buy one. When other high school boys were staring at the centerfold of playboy I was staring at the HP28 review
