I’m still using my HP 32s that I bought in 1990. No one else around here will use it because it’s RPN.
Before this one I saw one in a pawn shop
Asked to see it
Told them possibly it was broken.
I pushed some buttons and said I tried like 6x5 and i can’t even get an answer
I figured the odds they could work it were an almost almost infinite improbability but 40 years ago there were 2 genders and two types of calculators
