carlson explorer 2 never used for sale with survey ce

Hi,
I bought a Carlson explorer 2 with carlson c.e. for a China job 7 years ago, but never used it, just stuck to my hp 48 with cogo which is enough for my construction work.
I cant remember what I paid, I remember calling one of the Carlson's before I bought it.

Anyway it was several thousand dollars I remember, its registered in my name with the papers etc. I bought a new genuine battery for it the other day, so if anyone wants to purchase it, offer me an honest price.
It has never left the draw, or been used, I entered some points into it the other day just to play with it.
Can the Carlson software been tranferred or onsold, I have the disk back at home in Australa, you are welcome to have that as well.

Cheers
David
