I have a question about the method to connect the nspire and downgrade from os 3.0, i found this page (Sorry it is in Spanish):
http://www.pablin.com.ar/electron/circuito/mc/ttl232/index.htm
Is possible to use this old mouse port pins ( TxD GND and RxD ) directly with the nspire or a converter is absolutely necessary to downgrade the OS???
Thanks for Help

A converter is necessary because there is a difference in voltage levels.

The Nspire is using TTL.
So you should get a USB<->TTL converter. That's the simplest way.

If you still have a DB9 plug, you can use a RS232<->TTL converter, but you'll need an additional connection to power it.
If not, you can still use it by chaining it with a USB<->RS232 converter.
