 | preos071.zip | 841k | 04-11-05 |  | PreOS 0.71
The best kernel (or "shell") for the TI-89, TI-92 Plus, Voyage 200 and TI-89 Titanium strikes back (Updated November 2004), 100% compatible with AMS versions up to 3.00 on HW1, HW2 and HW3. This kernel also comes with standard libraries, and the graphics library fully supports grayscale on all HW versions. Includes complete source code. Also features advanced crash protection. The libraries can be compressed and archived, but must be in the executable, current or system folders (It doesn't search anymore in all folders).You can also select the program to launch with SHIFT+ON when installing PreOS. It adds a 89 emulator for the Titanium. It is distributed under the GPL. It fixes 4 bugs and should be very stable. |
 | preos067.zip | 916k | 03-07-24 | | PreOS 0.67
Absolutely the best kernel (or "shell" as it is sometimes called) for the TI-89, TI-92 Plus, and Voyage 200. This is now the most current of them all (updated July 2003) and it is 100% compatible with AMS versions up to 2.09 (and quite possibly new ones that are released later as well) on both HW1 and HW2, with no HW2Patch needed. This kernel also comes with standard libraries, and the graphics library fully supports grayscale on all HW versions. Includes complete source code. Also features advanced crash protection and can run libraries compressed and archived. |
