Postfix algebraic scientific calculators still in production
I grew up with Casio scientific calculators in the 70s and 80s and got used to their mode of input. They used an algebraic mode with normal order of operations for binary operators and parentheses to change evaluation order, but functions of one variable used a postfix operation similar to RPN, e.g. "30 SIN" rather than "SIN 30".

The only scientific calculators that work that way I can think of that are still in production are the TI-30Xa and TI-30 ECO RS. Are there any others?
