The 35s still comes without entry line different from x.

The different initial RPN implementations probably just reflected that RAM was expensive. I guess it paid to blow up the ROM code instead to introduce all sorts of tricks to make this work for the user (while being inconsistent over different models).

The first model with a fixed stack and an entry line was the 20b. This was the end of an era, and it came not too soon. Thanks, HP.
