The HP-18C was HP's first RPL-based calculator even though this model was not user programmable. The user did have a solver (another HP first) available, and is very similar to the HP19BII, but missing RPN logic.

This calculator was the intermediate step between the current HP 17bII and the old, Pioneer-style HP 17bII. Main differences with the original are increased memory (up to 28 kb), and the currency exchange menu. There is as well the "key feel": while both have good tactile feedback and never miss a key, some called "hollow" the keyboard touch of the 17bII+

The calculator is in perfect shape, with some dust specs in the screen (already there when I bought it). However, the pouch is a little bit "battered" - see enclosed pictures.
