Added a classic to my retro collection: the HP 15C calculator from 1989. 🧮 Features reverse Polish notation, root finding, integrals, complex numbers, and matrices. A true gem! #RetroTech #HP15C #VintageCalculators

Always bugged me that HP set an automatic push before the next numerical input after an operation as we see with the 5 key pushing the 12 and the 7 key pushing the 42. #HP12C #HP15C Practical, but if you have been off the calculator for a while it can be confusing.
