原型机是有SD卡的~貌似TI打算推出带SD卡的扩展坞了。

法文看不懂……那个所谓的扩展坞，要是放到中国来卖肯定又要卖到几百……
os2.2前两天不是还有谣言吗？怎么os3.0都有截图了？
仍然期待3D作图和SDK……

OS 1.1-2.0 default speeds:
- Base frequency: 180 MHz
- CPU frequency: 90 MHz
- AHB bus frequency: 15 MHz

The max possible after using Nover:
- Base frequency: 180 MHz
- CPU frequency: 90 MHz
- AHB bus frequency: 45 MHz

This almost doubles the execution speed of TI-Nspire BASIC and OS functions.

However, OS 2.1 is different. Here are its default settings:
- Base frequency: 240 MHz
- CPU frequency: 120 MHz
- AHB bus frequency: 60 MHz

TI made that OS compatible with faster speeds to accommodate the OS's slower execution speed. At this configuration, the OS appears to run slightly faster. The removal of the limitation, however, allows critor's program to set the speed of the TI-OS even faster than in 2.0.1 or lower, though:
- Base frequency: 300 MHz
- CPU frequency: 150 MHz
- AHB bus frequency: 75 MHz

In other words, this would be between twice and three times faster than OS 2.0 running without Nover's support! However, remember that OS 2.1 has some downsides, such as its larger file size (although this can be solved with a previous program we posted news about) and your machine needs Boot2 1.4, not 1.1, else OS 2.1 will not start-up on it. In other words, if your TI-Nspire came with OS 1.1, make sure to install OS 1.4 through 2.0.1 on it and start it at least once prior installing OS 2.1!

Anyway, if you want to try the program, you can download it here! Be careful to which settings you choose, though, especially on older OSes, else, use it at your own risk!
