The first known use of the terms in print in a programming context appears in a 1965 edition of MIT's Tech Engineering News. The use of foo in a programming context is generally credited to the Tech Model Railroad Club (TMRC) of MIT from . In the complex model system, there were scram switches located at numerous places around the room that could be thrown if something undesirable was about to occur, such as a train moving at full power towards an obstruction. Another feature of the system was a digital clock on the dispatch board. When someone hit a scram switch, the clock stopped and the display was replaced with the word "FOO"; at TMRC the scram switches are, therefore, called "Foo switches". Because of this, an entry in the 1959 Dictionary of the TMRC Language went something like this: "FOO: The first syllable of the misquoted sacred chant phrase 'foo mane padme hum.' Our first obligation is to keep the foo counters turning.", computer-dictionary-online.org One book describing the MIT train room describes two buttons by the door labeled "foo" and "bar". These were general-purpose buttons and were often repurposed for whatever fun idea the MIT hackers had at the time, hence the adoption of foo and bar as general-purpose variable names. An entry in the Abridged Dictionary of the TMRC Language states:
