The Davros of the Unbound Universe utilised a computer in his laboratory onboard the Quatch mothership during the Quatch Empire's second attempt at conquering the Unbound Universe's Skaro.
When the Unbound Doctor confronted Davros in his laboratory during an attack on the Quatch mothership by the Doctor, Alistair Gordon Lethbridge-Stewart and the Daleks, he inputted into Davros's computer information extracted from the data bank of a Quatch prisoner that the Doctor, Alistair and the Daleks had interrogated after the Daleks and Alistair caused the ship that the Quatch prisoner was onboard to crash. This information revealed to Davros that the Quatch were responsible for the attack on Skaro that led to the Kaled-Thal War, and ultimately influenced the creation of the Daleks by Davros. Deciding to achieve vengeance against the Quatch for their actions against him and Skaro, Davros allowed the Doctor to escape the Quatch mothership, before ordering his computer to deactivate the technology stabilising the Quatch in the Unbound Universe, thereby forcing the Quatch back to their native dimension. Shortly afterwards, Davros's computer was destroyed, along with Davros himself and the entire Quatch mothership, by the vast instability generated by dozens of Quatch being forced back to their native dimension.
