Yes indeed! However when I first took one apart (if I remember correctly to see if anything could be done about the keyboard bounce) I was a little bit disappointed to see that there is almost nothing inside!

They cheated a little bit by putting all the discrete stuff inside the battery pack where it is used to convert the 2.4V of two NiCd cells into stabilised 9V. Later models from Ti did that with a single cell inside the pack. I wonder why no one else came up with that concept.
