Running Debian on a Graphing Calculator

While the ubiquitous TI-83 still runs off an ancient Zilog Z80 processor, the newer TI-Nspire series of graphing calculators uses modern ARM devices. [Codinghobbit] managed to get Debian Linux running on a TI-Nspire calculator, and has written a guide explaining how it’s done.

The process uses Ndless, a jailbreak which allows code to run at a low level on the device. Ndless also includes a full SDK, emulator, and debugger for developing apps. In this case, Ndless is used to load the Linux kernel.

The root filesystem is built on a PC using debootstrap and the QEMU ARM emulator. This allows you to install whatever packages are needed via apt, before transitioning to the calculator itself.

With the root filesystem on a USB flash drive, Ndless runs the Linux loader, which starts the kernel, mounts the root filesystem, and boots in to a Debian system in about two minutes. As the video after the break demonstrates, this leaves you with a shell on the calculator. We’re not exactly sure what to do with Linux on a graphing calculator, but it is a neat demonstration.

Vista on a PS3


Apparently you can run pretty much anything on a PS3. [mopx0] has managed to get Vista running on his PS3. He used Qemu 9.0.1 to install Vista on a PC. He says it takes “about a day or so”, after using Vlite to speed it up, so be patient. You then make an image of the install and copy it to your PS3. Don’t worry though, your hard work will be rewarded by a speedy 25 minute boot time when you’re done.

Even though it is extremely slow, to the point of being nearly unusable, its good to see people pushing the boundaries of our hardware’s intended use.
