Hey, check out ticalc.org soon, I just uploaded a fast, graphical periodic table program for the 82 (Basic) It is really good for basic to say the least. Watch for v.8c of a super mole conversion program I am working on; prolly monday or tuesday-it might use the periodic table also. Oh, one more thing, an enter-the-symbol-get-the-info program will come soon also. later.....
