The display is the same type of display, but a completely new display (since there are significant indicator changes).
The chip running the code is the Atmel as Marcus said. This required a complete re-write from the ground up because:
1. Not enough space on the old one for new features.
2. Difficult to work on the old codebase (assembly vs C).
3. Doing so allowed reuse of the same math library that has now been used on the 20/30b, 10bII+, 12cp iphone versions, and the calc pad PC software.
4. Didn't have enough speed to do things like inverse T with any hope of enough speed.
5. The 20/30b codebase could be used as a nice starting point.
So basically like you said, the keys that were there didn't change (except very minor ones like changing C SIGMA to C STAT as it was clearer - the position didn't change), and the look/body didn't change. The hope is that the vast majority of 10bII users wouldn't notice a difference other then the calculations now go faster and there are a few more features. :-)
However, in actuality had a lobotomy to put in a new brain and guts. It's a zombie calc! :-)
