Abstract: MULTI is a general purpose, high speed, high energy physics
interface to data acquisition and data investigation system that
runs on PDP-11 and VAX architecture.  This paper describes the
latest version of MULTI, which runs under RSX-11M version 4.1 and
supports a modular approach to the separate tasks that interface
to it, allowing the same system to be used in single CPU test beam
experiments as well as multiple interconnected CPU, large scale
experiments.  MULTI uses CAMAC (IEE-583) for control and
monitoring of an experiment, and is written in FORTRAN 77
assembler.  The design of this version, which simplified the
interface between tasks, and eliminated the need for a hard to
maintain homegrown I/O system is also discussed.
