Title: TI-Nspire OS 1.8
Post by: critor on August 15, 2011, 05:45:42 pm

Thanks to Adriweb, here's the first photo of the TI-Nspire 1.8 OS, proving that it did exist.

It's the 1.8.0 CAS OS running on a basic TI-Nspire:

Seems the different protections can be bypassed with developer OSes and/or calculators.

I remember some rumors about 1.8 before, but then 2.0 came out. Interesting find.

Was there ever an OS 1.5 by the way?

I think there has been.
It's mentionned in this thread (3rd post):

So OS 1.8 existed before being renamed to 2.0? Interesting :)

I got mine in April 2009, I guess it must've been sitting on the shelf a long time...

You can look behind it : the number at the bottom ends with something like " S - 0407 " <- this is mine, April 2007

Mine was manufactured in May 2008, then.

Necropost: So P-0609E means it was manufactured in June 2009. And it came with OS1.4. Lol.
