These Casio calculators were what we cared about in Portugal, about 40 years ago, TI was nowhere as relevant, and next level would be an HP 48 GX instead.

I started with FX-4500P during high school, and later upgraded to a FX-880P during university, both still working.

By the way, you could get an additional 32 KB for the FX-880P, at a whooping price of 100 euros in today's money adjusted for inflation, talk about RAM prices.

Great work.

In college in Brazil, the rich engineering students had HPs (41s first, 48s later) while the average kid had a CASIO. The really lucky ones had a BASIC-powered calculator. I was very lucky in getting a PB-700. Not much memory, but allowed me to quickly translate a FORTRAN program to BASIC to do a table-run during a test.
