A Rakata Computer was a computer constructed by the ancient Rakata of the Infinite Empire. These computers were used both as data archives, accessed through computer terminals, and as devices for controlling doors or other systems. Due to the peculiarities of the technology, the systems of such computers were self-sufficient enough that they could repair themselves. As a consequence, after the fall of the Infinite Empire, the Rakata Computers survived tens of millennia. Two of these terminals were located on the planet Dantooine, in the ruins near the Jedi Enclave, and two more on the Rakatan homeworld of Lehon.
In 1000 BBY, the Sith Lord Darth Bane visited the lower levels of the Temple of the Ancients on Lehon to search for any dark side artifacts, eventually coming to the room with the remains of a massive Rakatan computer, which was broken beyond repair. While in the room, Bane finally found and retrieved Darth Revan's Sith Holocron, which was hidden behind the stone in the wall behind the computer.
