Titor’s time travel & the IBM 5100

The year is 2036. Decades after the global nuclear war, an American soldier named John Titor is assigned to travel back to 1975 and retrieve an IBM 5100 computer. During this mission, John makes an unexpected stop in 2000 “for personal reasons.” He connects with his family — and his 2-year-old self! And he interacts online with a group of time travel enthusiasts, sharing information about the future and a detailed description of how his time machine works.

  • I spent many, many hours programming the IBM 5100 computer. In APL of course. When did a )SAVE or a )CONTINUE on the tape drive, it made different patterns of noise with the tape going back and forth, and i can still remember how I could tell what kind of write it was doing based on the sound from the tape drive.

    Hi Beth… On Friday I was explaining to someone how my first job with computers was mounting tapes… And realized mid-sentence that this just sounds obscene in today’s world where the moving parts have become so compact, we are less and less aware of that they exist at all. Thanks for contributing your remembrance!

    I would also like to take this opportunity to pass on a big congratulations to Hot Docs and the director of How to Build a Time Machine, Jay Cheel, for achieving their goal for the first ever DocIgnite crowd funding campaign here in Canada.

    And thanks everyone for the views and re-tweets folks.
