I have a TI-89 Titanium calculator. Can I download games like dopewars or tetris onto my calculator? if so how? Are they freeware or do they cost money
You need to get the conectivity kit.
I wrote some games for my TI-85 back in the day…a football sim and a breakout-clone. Alas, my Calculator-to-PC cable is nowhere to be found…
I’m assuming you know you can enter the source code by hand, or that you can cable your calculator up to someone else’s who already has the program and transfer data between them.
Many many many games (and actual useful programs) can be found on http://www.ticalc.org
