Re: Suggestions for TI to improve their TI-89 / TI-92 calculators.
I agree "The ti 89 is an awesome calculator with a great basic language
built in." More speed and more
memory is always a plus. If we all get wishes and I guess we all do, I
would wish for the ti-89 structures
to be usable on directly my computer. I don't care if it would be just
for the Mac or PC's or both. I would buy a new computer or do whatever
is needed to get my old computer to run it. Such a program would be such
a pleasure to use.
Well, wishing doesn't cost much.
Good Luck All
