RE: CASIO fx-4000P scientific calculator from 1986
When in college with my 15C in the late 1980s, I remember a few friends with Casios like this or very close. I liked them a lot except for the cardinal sins of being non-RPN and rather mushy non-click buttons. But, a decent display and very pocketable!

I must restrain myself from branching my collection into old Casios as well. Stop. Stop now.
