John Titor claimed to be assigned to a governmental time-travel project. Purportedly, Titor had been sent back to 1975 to retrieve an IBM 5100 computer which he said was needed to "debug" various legacy computer programs in 2036. The IBM 5100 runs the APL and BASIC programming languages.
Titor had been selected for this mission specifically, given that his paternal grandfather was directly involved with the assembly and programming of the 5100. Titor claimed to be on a stopover in the year 2000 for "personal reasons", to collect pictures lost in the (future) civil war and to visit his family, of whom he spoke often. And then, after about a year of posts, he vanished: disappeared to who knows where?
