You must have had a special edition of the 25C, otherwise you should take a closer look at the left column on the keyboard. ;-)

I admit having looked at a 29C when claiming that. Assumed they took over the scheme of the 25C which isn't true obviously. Thanks for pointing me to that. Seems I tend to attribute better consistency to vintage HPs than they really showed.

But my real point was (and is) the nonexisting need for programmability in a basic RPN calculator.
