In the mid-to-late 2000s, you either knew, or were, that kid in grade school. You know. The one who could put games on your graphing calculator. You may be surprised to learn that some of these people didn’t exist totally in a vaccuum. There was in fact a thriving scene of hackers who had bent these calculators to their will, writing games, math software, and more generally hacking on the platform just for the sake of it.
Two player Tetris over the link cable on the TI82/83 was really cool ;)
Yes, everybody always wanted to sit next to the guy who had a jack-to-jack link cable during math class ;-)
Unlike the models from the article who had a Z80, our TI-92 had a m68k MCU, but there were some nice guide that you could read directly on the calculator between two Tetris games :-)
