One is used, with wear on screen. Also, the screws where the pen is stored show some rust. Screen still accepts signature.

The other looks unused- no marks,etc. Tested and accepts signature.

Both are nine pin but can be converted to USB with an adapter. There is ONE adapter included (tested with both units and both units work). 

Also included two magtek card readers (USB) but with only one cord. Both readers plugged in and light up.
