In his online postings, Titor claimed to be an American soldier from the year 2036, based in Tampa, Florida. He said that he was assigned to a governmental time-travel project, and that as part of the project he was sent back to 1975 to retrieve an IBM 5100 computer, which was needed to debug various legacy computer programs that existed in 2036
The big news will be that John Titor is being sent back in time to save us from the Epochalypse:
