Thanks to for the tip! Posted in computer hacks, Retrocomputing Tagged calculator, retro, texas instruments, ti, ti-84,, z80, zshell As it stands, there may be more decades of these types of projects to come, since neither TI nor the various testing standardization companies and government agencies show any signs of changing any time soon. It looks like the world of TI hacking is alive and well now, and with several decades of projects to browse there’s always something new to find.

There are also several methods of running native code or otherwise “jailbreaking” these devices to run arbitrary code. There’s plenty to catch up on here, too, from custom TI games that trick the two-tone display into grayscale to Game Boy emulators that can play Zelda since the TI and Game Boy share the same processors. While this isn’t great for getting value for money, it does mean that generations of students have been able to hack on these calculators to do all kinds of interesting things as outlines.Įven before the creation of these graphing calculators, the z80 processor behind them was first produced over four decades ago and was ubiquitous in the computer scene at the time, which also lends to its hackability.

Also because of standardized testing, these calculators have remained essentially unchanged for decades. Some black sheep may have other types, but largely due to standardized testing these calculators dominate the market. The gold standard for graphing calculators, at least in the US, are the Texas Instruments TI-84 series.

It would also offer a nice change of pace from writing Snake in TiBASIC, a BASIC dialect in which incidentally has also written a ray tracer.Ĭontinue reading “Ray Tracing On A Modern TI Graphing Calculator” → Posted in Misc Hacks, Software Development Tagged graphic calculator, ti-84

Even if using a TI-84 Plus CE to render the next Pixar-level movie isn’t the most productive use imaginable for these devices, this project and the CE toolchain make it all too easy to tinker with these $150 devices. Perhaps the most interesting part about this project is its use of the Clang-based C & C++ toolchain for the TI-84 Plus CE which gives easy access to the calculator’s hardware and related, including graphics, file I/O, fonts, keypad input and more. Although the eZ80-based CPU in the calculator is significantly more efficient than a Z80 as found in many 1980s home computers, the demo scene at standard resolution takes about 12 minutes to render, as also noted on the GitHub project page. This is excellent news for anyone who has one of these calculators, along with a lot of time, perhaps during boring classes, to spare.Īs demonstrates in a video, also embedded after the break, it’s not quite the real-time experience one would expect from an NVidia RTX 30-series GPU.

For the same reason there obviously is a way to do ray tracing of 3D scenes on a modern-day TI-84 Plus CE graphical calculator. Something being impractical isn’t any reason not to do it, which is why just about anything with a CPU in it can run Doom by now.
