This paper describes the hydrogen-line interferometer system at the National Radio Astronomy Observatory. The system consists of telescopes, receivers, a data acquisition program, and a reduction program. The reduction program uses a random-access data base which stores both the interferometer data and the synthesized maps. The calibration, mapping, and display of the data are described in detail
