Lear Siegler

Lear-Siegler is an American corporation which has produced a multitude of goods for a very broad range of fields. Chiefly to our interests, they produced display terminals during the 1970s. Most famous of these is the ADM-3A, a terminal of good quality and low cost which became a "de facto" standard. Lear-Siegler continues to produce technological products, if not computer terminals themselves anymore.
