calculator programs

i’ve used all of these programs on a ti-86 calculator, and most of them on a ti-85. i don’t think ti makes those anymore and i’m not sure if any of their current models can run these programs. all programs are available for download as as zip file that contains an 85_ or 86_ file that can be transfered to a calculator with a utility such as connect-85 or the official texas instruments software, or at least they could back in 1998.
