Product no.: HP 18c - USED

HP 17bII+old - USED

Product no.: HP17bII+old - USED

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.
