The Aurora FN1000 calculator is believed to be a clone of the HP 12C. [IMG]http://i167.photobucket.com/albums/u151/topoguy/aurora_fn1000.jpg[/IMG]

It has an alpha key, which the HP 12C does not. any idea how the alpha key is used?

The usage of the alpha key is explained (at least in part) in the picture you posted- See the right half of the case where the examples are. In the example it is the shift function for the orange legends.
