 | 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. |
