Infos Draco - what is this?

Hi! I chanced upon a strange thing in a thrift shop today. A hand-held terminal of some sort called Infos Draco. It was rather expensive (SEK 250) so I never considered buying it, but I wonder what it is. The case is mainly blue with some yellow and red details. Keyboard is in ABCDE (rather than QWERTY) fashion. The longest side is approximately 10" and it is shaped like an L turned up-side-down with a 40x8 character LCD screen on top. There are no manuals but the box seems to indicate Italian origin. It seems to run on batteries but can be plugged into the wall as well (standard Swedish 220V plug). There is also a phone connection and what appears to be a parallel port. I tried to start the thing, but only succeeded in a red light coming on and a happy beep when I pushed the ON button. What is it? What can it be used for? Does anyone want me to buy it for you? /F
