Is he a real time traveler: Who is John Titor?

John Titor said that his real name was different, but he used John Titor as a pseudonym because he was not allowed to reveal it. He said that he was a soldier working for the government in 2036 when he arrived and that he had to go back to the 1970s and find the IBM 5100 in order to debug the computers in 2036.

John Titor opened a blog and shared the events and prophecies that he claimed would happen there. One of the first things he does, when he emerges, is send pictures of the time machine and its user manual. In this way, he tried to prove that what he said was true.

John Titor and TimeTravel_0 are pseudonyms used on The Time Travel Institute and Art Bell's Post-to-Post forums during 2000 and 2001 by a poster claiming to be an American military time traveler from 2036. Titor made numerous predictions regarding calamitous events in 2004 and beyond, including a nuclear war. Inconsistencies in his explanations, the uniform inaccuracy of his predictions, and a private investigator's findings all led to the general impression that the entire episode was an elaborate hoax. A 2009 investigation concluded that Titor was likely the creation of Larry Haber, a Florida entertainment lawyer, along with his brother John Rick Haber, a computer scientist.

John Titor, who arrived on November 2, 2000, disappeared on March 21, 2001, saying that he would return in the year 2036. He was never heard from again.

John Titor gave clear answers to the questions asked for the year 2036 and even to almost every question asked to him.

IBM 5100 was the first personal and portable computer produced. It was introduced in 1975. It weighs 24 kilograms and has 16-64 Kbit RAM and 32-64 Kbit ROM. One unit is the size of a small suitcase, including a keyboard, a 5-inch CRT screen, and other parts. Optionally, it can be carried with a carrying bag. This is where the name “Portable” comes from.

After the IBM 5100, which was introduced in September 1975, the term "IBM personal computers" was used by BYTE magazine in December 1975.

The IBM 5100's CRT screen could display 16 lines of 64 characters. Additionally, an external monitor could be connected to the IBM 5100. The IBM 5100 was available in two programming languages: APL and BASIC. There was a toggle switch on the front panel as it supported both languages.

The IBM 5100 was based on the concept of debugging using an emulator written by IBM in microcode. In other words, a small, cheaper computer can rewrite and debug programs that have already been written for a larger, much more expensive computer.

John Titor also came to buy an IBM 5100 for this debugging job, as he claimed.
