I've more than one (TI-59 as well as PC-100) and the devices are -ahem- problematic.
TI-58/59: Keyboard is prone to bouncing up to the state of complete uselessness.
TI-59: Card reader fails
PC-100: The printheads or the drivers may be blown, the controller can be defective or the complete board is more or less destroyed by corrosion because of gas leakage by the batterie pack left in the charger compartment of the printer over years.
Just buy such a combo only, if the seller guarantees that every piece works and there is no battery pack left in the printer. And you will need the key!
