ndless- OS v1.7, v2.0.1 or v2.1.0 installed on it. v2.0.0 is not supported, you
  should update your OS.
如图。记得有提到os2.0.0  没有  ndless。。
boot1 1.1.8196
boot2 1.4.1571
那么该如何备份？

dump os 的原理，我猜测一下，就是找个专门的电路，可以对ns机器里面的rom芯片进行按地址逐位扫描并读出其中的数据保存下来。

Could we have your OS backup file ?

I think we have no 2.x development OS (only production OS), and so it could be very useful to repair other TouchPad prototypes which cannot be upgraded. :)

as far as i know,all the touchpad prototypes(including CAS and non-CAS) are denpending on the bases of production nspire with clickpad(i successfully update them into 3.6 with nlaunch. IN nsnandmgr,there are the right type words showed on the left of the top.)
by the way, is there any on-nspire ansi C compiler ? i am taking some programming courses and this kind of tools would be helpful

here is the link for that temp.tno(2.0.0.717)
