Comes with:

Calculator is in excellent working condition. Buttons are all tactile, and responsive. Passes all onboard tests. I updated the firmware to the latest version 2.15 via SD card and can confirm that the card slot works. There are some scratches on the front plastic shell. The battery compartment springs has some rust on the bottom spring (see pictures). Leather case has some marks on it. 

It can solve system of equations and I programmed it to toggle results from polar to rectangular form and vice versa when working with 3-phase power. Lot's of confidence when entering keystrokes due to tactile buttons.
