One of the first widely-accepted memory lighting control systems, installed primarily in very large theatres, opera houses, and high-profile TV studios. Made by Thorn in England, and sold in the US by Kliegl. See also http://www.controlbooth.com/wiki/Collaborative+Articles:Memory+Lighting+Control+Systems+History.

The Q-File was also the impetus behind the creation of ETC's first console: the Mega-Cue. When Bill and Fred Foster looked at a Q-file and heard the price, they said "That's ridiculous--we could build one for $5000." And so they did. [See also the post at http://www.controlbooth.com/forums/lighting-electrics/13924-call-q-file.html#post136640 .] It was introduced in a hotel room in Washington, DC at the 1977 USITT conference, where they showed it to manufacturers who might want to build and sell it. The problem came from Kliegl Bros.: the Fosters got gazumped by the introduction of Gordon Pearlman and Steve Carlson's Kliegl Performer. However, it could be argued that, in the end, the Fosters had the last laugh [as Kliegl began a long downhill slide, eventually ceasing operations in 1991].
