/tmerk'/ The Tech Model Railroad Club at MIT, one of the
wellsprings of hacker culture. The 1959 "Dictionary of the
TMRC Language" compiled by Peter Samson included several terms
that became basics of the hackish vocabulary (see especially
foo, mung, and frob).
By 1962, TMRC's legendary layout was already a marvel of
complexity (and has grown in the thirty years since; all the
features described here are still present). The control
system alone featured about 1200 relays. There were {scram
switch}es located at numerous places around the room that
could be thwacked if something undesirable was about to occur,
such as a train going full-bore at an obstruction. Another
feature of the system was a digital clock on the dispatch
board, which was itself something of a wonder in those bygone
days before cheap LEDS and seven-segment displays. 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".
Steven Levy, in his book "Hackers", gives a stimulating
account of those early years. TMRC's Power and Signals group
included most of the early PDP-1 hackers and the people who
later bacame the core of the MIT AI Lab staff. This
dictionary accordingly includes a number of entries from the
TMRC dictionary (via the Hacker Jargon File).

/tmerk'/, n.
The Tech Model Railroad Club at MIT, one of the wellsprings of hacker
culture. The 1959 Dictionary of the TMRC Language compiled by Peter Samson
included several terms that became basics of the hackish vocabulary (see
esp. foo, mung, and frob).
By 1962, TMRC's legendary layout was already a marvel of complexity and has
grown in the years since. All the features described here were still
present when the old layout was decommissioned in 1998 just before the
demolition of MIT Building 20, and will almost certainly be retained when
the old layout is rebuilt (expected in 2003). The control system alone
featured about 1200 relays. There were scram switches located at numerous
places around the room that could be thwacked if something undesirable was
about to occur, such as a train going full-bore at an obstruction. Another
feature of the system was a digital clock on the dispatch board, which was
itself something of a wonder in those bygone days before cheap LEDs and
seven-segment displays. 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.
Steven Levy, in his book Hackers (see the Bibliography in Appendix C),
gives a stimulating account of those early years. TMRC's Signals and Power
Committee included many of the early PDP-1 hackers and the people who later
became the core of the MIT AI Lab staff. Thirty years later that connection
is still very much alive, and this lexicon accordingly includes a number of
entries from a recent revision of the TMRC dictionary.
