MACRO is a large area detector designed to search for rare phenomena in the cosmic radiation (GUT monopoles or supermassive charged penetrating particles), to study the penetrating cosmic ray muons, to detect neutrino bursts originated by gravitational stellar collapses in the galaxy and to perform a survey of cosmic point sources of high energy neutrinos. The detector, located at a depth of about 3,600 meters of water equivalent in the INFN Gran Sasso Laboratory (LNGS), has an acceptance of about 10,000 m[sup 2]sr for an isotropic flux of particles. It consists of plastic streamer tubes, liquid scintillation counters and track-etch detectors arranged in a modular structure, the basic element called ''supermodule'' having dimensions 12 x 12 x 5 m[sup 3]. Presently 6 supermodules are operative and have been taking data since June 1991. Here an acquisition system based on a network (Ethernet/DECNET) of KAV30 VAX processors is described. KAV30 is a VME single board computer based around rt-Vax 300 and running in VAXELN, a Digital Equipment software product for the development of dedicated, real time systems for VAX processors. A central VAX running under the VAX/VMS operating system is used as file server and as an interface of the acquisition system with respect to the user's world.
