+1 on the 15C.

Bought mine in 1982 for $85 add still use it today. I honestly think you’ve changed the triple button cell batteries like four times over the years.

I remember losing it once in college, and couldn’t afford a new one. I thought it might have slipped out of the rat trap on my Honda 650. Searched the parking lot at school the next morning and there it was, on the ground with tire tracks across it. Powered up fine add still runs like a top.

Speaking of losing one ... my original 15C was stolen from me at a manufacturing facility. I made it known I knew it was stolen. It reappaeared in the purchasing agent's office.

Had it NOT been RPN, it would have been lost forever.

Years ago I read an article on the HP12C. The author mentioned that he once interviewed a CFO. He saw the CFO had an HP12C and he asked why he still used it. The CFO picked up the 12C, whipped it against the wall, picked it up and turned it on for the author and said "that's why."
