Because of the size of the screen, a SCROLLING periodical table would
be a good idea.
The second way to do it would be to write the elements tinier, but
it wouldn't be really nice and efficient.
I don't pretent to reinvent the wheel, so of course, there are already
good periodical tables for TI-92 (I had it before), and making kind of
the same program would cool for all the guys who own a TI-89.
Once more, I would love to try to do that by myself, but I don't have the software to do so. (An 68k assembler for mac would be welcome !!)
