      Observe the Jargon File's view of it:

      TMRC: /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 decomissioned 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.

  34. Can't read the article, but ... by siliconwafer · · Score: 2, Informative

    Computer controlled model trains have been around for awhile now. It's known as direct command control (DCC) and it's a well known standard among serious model railroaders. I believe its specification is also defined by the National Model Railroading Association (NMRA).

    Basically, the flaws of regular DC model railroading are as follows: Each locomotive picks up DC power from the rails, and therefore, it is not possible to have two trains moving in different directions or different speeds unless the sections of rail are insulated. DCC was brought about, which allows each locomotive to be addressable, and "command controlled". A "decoder" is installed in each locomotive, which receives the command. The decoder is really just a PIC.

    I wonder if this the technology discussed in the article (which I can't get to right now) is a DCC derivative of some sort?

    Got a new train set and several buildings, etc for Christmas many years ago. Spent weeks building a 4'x8' table. Used the green bag-o-grass and glue instead of the paper, Huge Paper mache mountain with bridge, roads, buildings, street lights. Had everything installed, but not completely wired. That upcoming weekend I was going to finish everything. Hard Freeze in late February and a pipe in the Kitchen upstairs bursts. It must have been 2-3am and many, many, many gallons came down right on my mountain and then on my trains and then on the floor. The mountain melted, trains and track rusted, base was brown and the carpet was green.
