The listing, Texas Instrument Solar Powered Calculator has ended.
This is a great calculator with some scientific calc features. What I love best is you don't need batteries! Why don't they make all electronics like this? :) Works fine, I am having trouble parting with it so this accounts for the high starting bid.
Here is more info on this calculator. I got this info from online description of this model. It is used and does not have a booklet but you can likely find the instructions online.
