IN-4
this was a series of information droids produced during the New Order by Veril Line Systems. They could follow only basic instructions, and only if they received them from an identifiable source. The IN-4 series was based on the EG-series of power droids, having the same boxy form but equipped with a pair of heavy treads instead of legs. These droids were used extensively by many corporations and political Houses to store and retrive vital information, and had several interface jacks with which to gather more data from computer networks. In most cases, information retrieval systems were hardwired into the IN-4's computers, which meant that any attempt to steal the droid's computer core would result in the destruction of the droid as well as the information.
