A little earlier on Habré was already laid out the news that the classic Doom was ported to the TI-Nspire calculator . The game was played on a calculator without any slowdowns, although, of course, the display in this device does not give a very smooth “picture”. Nevertheless, this idea was also liked by other developers, and on similar calculators you can now play Super Mario, Zelda, and even Counter-Strike.
The configuration of calculators from Texas Instruments, including the Ti-83, TI-Nspire and Ti-89, is quite sufficient for running and more or less tolerable operation of these games. In the continuation there are several videos depicting the process of playing on calculators. ')
