HP 35s Stack: Bug?

Hello,

I just bought an HP 35s. The stack seems to be behaving oddly, and I'm not
sure if it's operator error or a bad calculator.

The stack seems to be double-entering my numbers. For instance, 1 <enter> 2
<enter> produces a stack of 2 - 2 - 1. Entering 1 <enter> 2 <enter> 3
<enter> 4 <enter> produces a stack of 4 - 4 - 3 -2, not 4 - 3 - 2 - 1 as I
would have expected.

Am I just doing something wrong?

RPL is not RPN. When you type a number, it is entered directly on the
stack. This means 2 (is already on the stack) ENTER (makes a copy).
Take a look at the part of the manual describing RPN operation. You
will need to take a look at it. I do the same thing when switching
back and forth from the 50 to the 35. Takes a few mins before I stop
doing it.

I'm more used to the HP 35/45/65/67 so I have a problem when using
the newer machines! The 35s brings back many happy memories.

Hey, thanks everyone for the help.

That's exactly what I'm doing -- switching from a 50 to a 35 (I wanted stash
a lighter calc in my backpack). I think I've gotten the hang of it, though
the manual could explain it better (even the full version is kinda vague).

Off to read more of the manual,
