I saw this calculator a few days ago, and I found that the mark was "TI nspire CAS" instead of "TI nspire CX CAS" or something like "TI nspire color CAS"
So I asked the seller for some pictures, here they are.
By the way, the seller told me that he had a PLT-FHH1, but the screen was broken and he doesn't have the right power adapter to test.
