Is it possible to program games on my TI(Teaxas Instruments) 81 ( a calulator) without downloading off the internet. If so, how do I do it? Links? ---

Yes. Read the manual. ---

Yeah, reading the manual is one of those “Something I might consider if I had some free time” things. In the meantime, downloading games off the net, finding someone else w/ a TI-81 and games or going to a site that has the code written out in addition to the actual program are your options. Links I have none, I’m sure someone else here has em. ---

The TI-81 has very limited memory. Newer models (like the TI-89) have more memory and can hold more (or bigger) games. There are plenty of [sites](http://www.ticalc.org/pub/81/basic/games/) that have existing games you can download and program into your calc. Or, like **friedo** said…read the manual. Then you can create your own! Back in high school, I created quite a few games for my calulator (Hi-Lo, Tic-Tac-Toe, Golf, 3-D maze, etc.). My favorite game was “Bathroom Hunt”. You had to search a house for keys to unlock doors in order to find the bathroom before you wet yourself. 🙂
