I bought a TI82 and mastered it only to find out that the local school used a CASIO. I was also volunteer tutoring at the local high school so set about learning the CASIO graphing calculator. I made a few view graphs for my own use and decided to market these. I then found that the state was mostly using the TI83 so I went to work and made vugraphs for the TI83. I sold a few, but the cost to make was a little high and I didn't sell too many. I then took the TI83 charts and reduced them to fit on 4 by 6 index cards and then bound them with a plastic comb. Since then I have sold about 110 of these booklets and have not had any negative feedback on them but have had quite a few positive feedback's. If you are interested, email me at the above address. I also sell them on Ebay. Here is the contents of the cards: MINIATURE CHARTS FOR USE WITH Texas Instruments TI  83 TABLE OF CONTENTS (***added in series II) 1. EQUATION SOLVER*** 2.
