In fact, why didn’t HP just make the 20b originally programmable like the whole world thought they must have intended to do from seeing that mistake?

It wasn't a mistake. Two products - two price points. What is so difficult to understand about that? That is a universal marketing/business strategy.

The manuals were meant to be the same for both products, with sections saying "in the 30b, ...." to include additional information for the custom features.
