RE: Postfix algebraic scientific calculators still in production
Years ago at the University, in addition to taking a typing proficiency test (35 words a minute for five minutes with five or fewer mistakes), you also had to take a 10-key proficiency test on an adding machine.

Add up lots and lots of numbers. Had to be very quick as well.
